Gli effetti collaterali del trattamento per animali domestici Revolution

 di amanda il 09 gen 2013 |

Only those who truly care about their families health, search for posts and articles like this one, which highlight the symptoms and potential side effects of different pet treatments. Which is why I know that tu are a kind and compassionate person, who only wants the best for every member of your family.
 
E sapere questo mi rende orgoglioso di scrivere un blog sugli effetti collaterali di Revolution per cani e gatti , perché so che lo utilizzerai per confrontare altri prodotti antiparassitari per animali domestici, in modo da assicurarti di ottenere la massima qualità di deterrente per i parassiti del tuo animale domestico. a disposizione.
 
Prevenzione parassita Springer Spaniel inglese
 
Con Revolution Blue dalla tua parte, il tuo gatto non avrà un prurito che non puoi graffiare. Sarai libero di sontuoso gattino con la quantità eccessiva di attenzione a cui si è abituato senza preoccupazioni o moderazione. Quindi, ferma quella coda dalle contrazioni e mantieni quella pelle dal prurito con Revolution Blue.
 
Muscle Weakness/In-Coordination - In 1% of clinical trials, some pets experienced extreme muscle weakness which lead to difficulty standing or walking. This can happen if your pet gets too large of a dose, or if they have a natural undiagnosed allergy to anything in the treatment. If this happens, your pet will need to see a vet right away. Because of this risk, it is always best to try any new pet treatments in the morning, so that if any adverse reactions appear, you will have plenty of time to get your pet into a vet within the same day.
 
Rapid Breathing/Panting - Because Revolution enters the blood stream, it can sometimes have a negative effect on your pets heart. In a small minority of pets, this can cause hypertension, which can lead to stroke or heart attach. If you notice these your pet is panting excessively or breathing very rapidly, take them into the near vet as soon as possible.
 
Muscle Tremors - If you notice that your pet is shaking uncontrollably or experiencing heavy muscle tremors, call your vet and schedule an appointment for as soon as possible.
 
Skin Burning - Out of 1743 animals tested, less than 2% had an adverse reaction that caused their skin to burn after application of any chemical pet treatments. If you notice that your pets skin appears is covered in a rash, peeling or your pet seems to be in great discomfort around the application site, you will want to take them into a vet right away.
 
 
 
La maggior parte di queste reazioni si verificano raramente in 5 animali su 100, il che significa che è improbabile che l'animale abbia una reazione grave. Sebbene sia armato con questa conoscenza, ti aiuta a prenderti cura di loro se capita di far parte del 5%.
 
E ora che abbiamo superato le parti più difficili di questa discussione, esaminiamo gli effetti collaterali più comuni e alcuni modi in cui puoi aiutare il tuo animale domestico ad affrontarli, mentre il trattamento li allevia dai parassiti.
 
Temporary Hair Loss - More often then not, this happens with animals who already have sensitive skin, and with most of those cases, the sensitive pet is even more in need of pest treatment than pets who are not so sensitive. Though because the pet has sensitive skin, they will sometimes lose some of the fur around the site where you put the treatment. So long as they do not appear to have been burned, they should regrow the hair within a week or two at most.
 
Digestive Upset - Diarrhea, vomiting and stomach upset are the most common digestive side effects. They can cause your dog or cat to not want to eat or play for a little while until their body has processed the parasiticide. You can help them through these side effects by making sure they drink plenty of fresh distilled water, which will help keep them hydrated and help them process the treatments more easily.
 
Hyperactivity - When Rivoluzione enters your pets bloodstream through their skin, it can sometimes cause them to have an elevated heart beat, as their body deals with the treatments reactions. This will make them anxious, as they will not be sure about what is happening to them, and that is usually what causes the hyper activity. You can help keep them calm by giving them their treatment in a dark and quiet room, and then staying with them for at least 30-45 minutes after the treatment.
 
Drowsiness - On the other side of the coin, some dogs and cats have seen the alter-reaction to hyperactivity, which is Drowsiness or letargo. As their body gives into the process of the pest treatments, they might need to sleep while the battle between bugs and love, wages on. If your animal finds themselves with this reaction, the best thing you can do is to help them get comfortable, and then check on them from time to time, to make sure they are still able to get up, walk around a bit and drink some water.
 
sbavando - It is recommended that every pet who gets a dose of Rivoluzione, gets it right between their shoulder blades, to prevent them from ingesting the medication. That being said, we all know that our pets have a way of reaching the spot, no matter how crafty you try to be, and that means that there is still a chance that they might ingest the treatment.
 
Quando ciò accade, molto spesso provoca un'eccessiva sbavatura mentre il loro corpo lavora per ottenere il sapore e le sostanze chimiche dalla bocca. Puoi aiutare il tuo animale domestico offrendo loro molta acqua fresca da bere.
 



In most cases, the worst you're going to see is a displeased cat or anxious dog, whom are not very happy to have been treated, but who will be very happy in an hour or so, as they are finally flea and parasite free again.

Questi sintomi sono esclusivi di Revolution o sono gli stessi per tutti i trattamenti di fuga? Lo chiedo perché è necessario un trattamento di fuga efficace. Ho provato quelli "naturali" inutilmente e un veterinario olistico mi ha detto che non esiste un'alternativa efficace.

My dog, now 8 years old, started having seizures every couple of weeks when he was 5 years and we traced it to starting "Revolution" as his flea and tick control medicine. Do not use this medicine if your dog develops "idiopathic epilepsy" meaning that a cause of the epilepsy cannot be determined: the cause is Revolution. We are now using the edible pill "Trifexis" and he has been seizure free for about 9 months now.

My cats are indoor cats. However, every couple of years I find a flea on one of them. I believe that flea eggs can be tracked indoors on the soles of shoes. Usually one dose of Advantage takes care of the problem. This year, my vet was out of Advantage so I bought Revolution. It was the first time I ever used it. When I gave it to my cats, one of them immediately started trying to lick it off. The other cat sat there, motionless, with a stunned look on his face. Later I figured out why: REVOLUTION WAS BURNING MY CATS’ SKIN.

The next day I saw that one of my cats lost his fur where I applied the Revolution. His skin in that area was red and he didn’t want me to touch it, meaning, it HURT. He LOST FUR from the harsh chemicals in Pfizer’s Revolution. I was very upset. I shudder to think—if this is the FDA-approved version available to the world and it is so caustic that it burns fur off of cats and causes such enormous problems as people are describing on this site, then what did the studies do to the poor laboratory animals they did animal testing on?

I will never EVER use this product again!

Please stop pouring chemicals on your pet. Check out this great book: “Homeopathic Care for Cat & Dogs” by Don Hamilton, DVM. It contains natural remedies for many pet conditions and has many suggestions for flea control with no side effects.

After this ORDEAL, I bathed my cat, who had licked all her Revolution off, in order to drown the fleas. It was a much better solution than toxic poisonous pharmaceuticals. Reason: 1) it worked 2) my cat did not suffer 3) it was free.

I've used revolution before & I never noticed an issue, but today was different. Very different. I applied the revolution in between Kitty-kitty's shoulder blades & shortly after is when it happened. Now, Kitty is not necessarily a "nice" cat, so her response was an indicator something was wrong. I came into the room & noticed her laying on her back with her legs curled up in the air. Initially, I thought Oh, how sweet. Then, I noticed she had vomit around her mouth, down her cheek, on the top of her head, & all over the sheets. I'm pretty sure she had a seizure. I scooped her up & cleaned her off & she just let me. She started purring & even let me cuddle her. She's been laying in the same spot for hours & each time I check on her she allows me to pet her much longer than she typically would. She's definitely not feeling well & im positive it's from the revolution.

Any animal can have a reaction to any medicine or vaccine. For example I have never had an issues with flea meds but my dog gets sick with diarrhea after getting the bordatella vaccine. Any time you give your pet a med make sure it's on a weekday so you can bring them to the vet if need be and make sure you will be around for 2 hours to watch them. It sounds like alot but that's just my advice. Also never split doses. Seems some people here who have had bad reactions try to split doses or give too much. Only give the smallest amount needed and only give every 30 days. He'll I'll even go 5 weeks sometimes before I give another dose. In addition don't give meds right after vaccines when your pets immune system is compromised. I also don't think people put two and two together after going to the vet to get flea meds but their pets probably just had vaccines too.

If anyone out there has an older pet and the vet wants you to use Revolution or any other flea medication on them, please don't and if you have please stop. I have had several CKD cats and even if a small portion of a topical flea med was given they all had a worsening of their kidney related symptoms for some time. Even if your cat has good kidneys that can change fast with toxic chemicals so do not chance it. Go and get capstar and use it once a week for a few weeks then every two weeks. The cat may scratch and get upset because the fleas bite when they are dying but it is not so hard on their system.

Cats generally live to be 19 or 20 years old if not using flea medication on a regular basis. Mine all have, but finally I used Revolution on them when they had bad fleas and both got Cancer at 19 and 20 years of age. Of course I can't draw a straight line to the revolution, which does kill fleas, but it's a prime suspect. If your cat is vomiting afterward, has sore patch from it and especially if convulsing, take immediately to a vet even if you have to pay from a credit card and go into debt temporarily.

I have had three different male cats get cancer and die. The common denominator was I used Revolution on two of them and Frontline on one. The cat I did NOT use a topical solution on lived to be 18. I'm connecting cancer to topical anti-flea solutions.

This is pretty typical results for all flea treatments. Whilst they can differ slightly depending on the different main ingredient. You'll find they all have a very small portion of animals reacting in similar ways. It's just like some people react to Penicillin even though it's the most common old school antibiotic ever used http://www.drugs.com/sfx/penicillin-side-effects.html.
A general statement but the post was mainly to help people be aware of any possible side effects so they can take action.

I have 4 different breeds of dogs,
3 of whom show no side effects of Revolution, I got a Beagle in the month of Nov 4yrs old, clean bill of health, in April started to give Revolution to the beagle and couple days later had his first siezure that I know about, called previous owner - never any history of seizures.
I did not put two and two together until the 3 time I gave him revolution, and always about 2-3 days after he has a seizure, I actually even skipped a month of no medicine and no seizure.

I read up on the internet and in some cases - Yes, there have been incidents of reported seizure. I am going to contact the company that makes this in inform them of my findings. Btw the beagle is still healthy afterward, vet says nothing I can do for the seizures, just be there for your dog. No more Revolution for my pup.

So same thing with my little chihuahua- I had been using nexguard & heart guard for 4 years at half doses since she threw up after front line topical. Then on get last visit the tech at north shore refused to sell me those Meds for her saying they were toxic & she should be on revolution. I refused since they had been selling me next guard and heart guard for four years. He was insistent it even went to the back and said that's what the vet said also.
I didn't push the matter and just put the revolution but I used up the rest of her next guard and heart guard and finally gave her the revolution application Friday night and made sure to really get it in between her shoulder blades against the skin. Sunday morning we went played in the park and I came home and I heard her Bells on her collar jingling in the other room & thought she was playing.
After about two minutes I want to see what she was playing for so long and she was seizuring on the floor- it was horrible -she was foaming at the mouth- it was heartbreaking. It took a lot of keppra, phenobarbital & Valium for a full 12 hours to get her stop having seizures -& the first vet discounted revolution when I mentioned that as the only different thing in her routine.
The third vet that took over her care -did her blood work & everything was normal - t4, liver ( close to moral), etc...he said it was possible that the revolution caused this & to never use it again. we r going to slowly wean her off the phenobarbital over a few weeks to make sure she doesn't have seizures again. But I can not stress enough how odd it is that so many people complain about their dog & seizures after revolution & yet it doesn't come up as a main side effect... Makes you wonder...

I have a dog I used it on just one time same problem, except he has continued to have seizures. He has had 3 now. Did your dog wean off the anti seizure med ok, anymore seizures after that? I have read the meds are lifelong. My other choice is MRI cost is about $3,500.00

My 2.5 Boxer collapsed lastnight. I applied Revolution on him the night before. My vet ASSURED ME it was safe and very rare side effects. I thought I lost my dog last night as he collapsed. Thankfully he came back and rushed him to the hospital. They couldn't find what was wrong I feel very strongly that this pesticide is the cause to his violent health change. :(
Of course vets won't push the possible side effects. These drug companies are in buisness with them and heart worm prevention is a million dollar buisness

We have been using revolution on our inside rescue dog and now she’s having seizures, in bad pain, lethargic, etc. How can we get this poison off the market? We had a Pomeranian years ago that went through the same problem but didn’t understand why? But we understand clearly that Revolution is poison to our fur babies!

Gave my Chihuahua a higher dose this time is what they gave me cause he gained a few pounds and he was panting all day in a cool car while I was driving. This was unusual for him, he is sleepy quite a bit, he is after 3 days still itchy, I found 2 fleas on him last night. This stuff is expensive for 4-5 drops of liquid. I think too much of my dog to give it to him again even tho he has had it before. No more resolution.

Since applying this product, my otherwise healthy cat has vomited once and subsequently developed extreme lethargy, anorexia and fever. He is an inside cat and never goes outside. Took him to the Vet who totally ignored the possible connection between Revolution and my cat's symptomatology. Blood work showed only slightly decreased lymphocytes; everything else normal. Cat is dehydrated and fluids have been subcutaneously administered twice now. Cat still is not eating or drinking and sleeps all the time. For an otherwise healthy 6 year old cat, the connection between Revolution and his symptoms is too strong to ignore. I will not be using Revolution again and will not take my cat back to this particular Vet. Have no idea how long these symptoms last and the websites I have looked at do not address the issue, just as the Vet did not.

Did your cat get better? How long did it take? I gave my cat Revolution 4 weeks ago and almost 3weeks ago and he started with a fever and being lethargic. It was the 1st time I had given him Revolution so I am not sure if there is a connection or not.

My adult cat who never goes outside was weighed by a vet tech - at 27.1 pounds and so was given the large AND a kitten dose of revolution. Experienced EXACTLY same symptoms you all have listed...terrible sneezing fits then lethargy, respiratory distress, fever, won't eat and won't use the litter box. At the vet we found that the tech weighed him wrong and he only weighed 15 pounds so OVERDOSE of revolution as well as adverse reaction. Vet thinks it is respirqtory infection and not related to revolution. But after internet research it is most definitely due to the revolution. I have to do subcataneous fluids at home, taking lysine anti-virals and had a shot of antibiotics yesterday. I am livid. Visiting vet today - they will treat but I will not pay due to their malpractice. Scott - follow up please with what happened to your pet.

Hi there, did your kitty get better and how soon? I just treated my 3 months old kitten with revolution, and he vomited last night. He doesn't show other unusual behaviour yet, other than drinking more than usual, but I started reading the forums and began to freak out about possible side effects. I keep wondering how quickly would they develop and how soon would they subside.

Cats need to eat or their kidneys begin to shut down! Take your poor kitty to another vet if he hasn't eaten in more than 48 hrs.... that could be life threatening. And a reputable vet will recognize your cat had an adverse reaction and clinically treat it as such....

I am having a problem with my persion cat. I started using Revolution on him about 1 - 2 years ago. Since then he has had sneezing fits, runny nose, and weight loss. I just took him to the vet, after going to several that just said wipe his nose, and he did blood tests and nothing wrong and also diabetes test and that came back ok. He got a steroid shot and allergy shot last week and the sneezing has let up but coming back a little. I gave him Revolution about a month ago and due again. I am just wondering if this is not the cause of this. I will not be giving him the Revolution. Sounds like a link to his problems. Thanks for posting this.

If he sneezes a lot he could have feline herpes. It sounds weird, but that's what my mom's cat had. He just needs meds sprinkled on top of his wet food twice a day. He likes the taste, so it is an easy fix. Don't worry, they can't be transferred to humans.

Any time you have doctors, whether vets or the kind for humans, selling a product for which they most likely receive a perk or outright payment, there is a huge temptation to ignore the side effects of a medication they are involved with selling. It's the same problem for doctors for humans. These doctors are reimbursed for chemotherapy and/or radiation. These treatments for cancer are the only ones for which doctors are directly reimbursed. I know someone who had cancer, refused chemo and radiation, but did have cancer tumors surgically removed and is cancer free seven years later.

Although Revolution can cause side affects, its proboaly the most safest method out their. Ive seen alot worst side affects. It really depends on the pets reaction to any of it. If their allergic to certain ones then bad things can happen. I don't suggest Hartz, Seargents or sentry at allll!!!! I have 4 cats and have applied to a others aswell, and no allergic reaction with revolution at all.

Gave revolution to my 9 week old kitten. He’s fine. Eating and playing like normal and it’s been 3 days. I know there’s risks in a lot of medications but natural products just don’t work and I am not sleeping in a bed or house with fleas. I love our animals but using chemicals is the only thing that works for us (regarding fleas) and all animals are healthy and happy. Our cat who just passed away of old age was 21 years old. I don’t think for majority of pets these medications are a death sentence as some would have you believe. Many pets use them and have zero reaction. If your animals does have a reaction obvioulsy stop using it.

I am a professional petsitter/animal care person and whenever I have seen revolution applied to elderly cats it is basically a death sentence. I had in my care some young, 3 years old, purebreds, a Bengal and a Havana Brown. Both developed urinary problems. The Havana seriously but he seemed to be predisposed. I notice they advise "distilled" water which is lower in mineral content--to prevent urinary crystals I suppose, which means they know this is a problem and already an issue with certain breeds of male cats especially. And I've seen Revolution used on indoor cats which are not exposed to heart worm risk!

I advise organic flea control and Frontline or Advantage only if absolutely necessary. This stuff only works the first week, so flea hygiene is absolutely necessary whether you use toxic assist or not. Sunlight or UV light kills eggs and larvae in 30 seconds of exposure. Flea traps work! See my blog on organic flea control at http://wholepetmind.wordpress.com/

L'anno scorso ho usato Revolution di un Maine Coon Mix di 8 anni o un grande pelo lungo domestico a pelo lungo che sembrava un Maine Coon. Ho avuto una morte improvvisa solo dopo aver iniziato a usare Revolution l'anno scorso. Quest'anno mi sono detto che se vedrò di nuovo qualcosa del genere dopo averlo usato lo saprò. Beh, l'ho usato una volta in estate. Poi il mio gatto di oltre 10 anni è diventato più letargico e ha avuto cambiamenti di personalità, ma non ci ho pensato molto perché era così vago e sembrava ok. Ma poi giaceva sul pavimento morto. Era 15 libbre, molto grande e muscoloso e non malato. Era un gatto domestico. Sono malato per questo e mi sto picchiando. La sera prima l'ho visto sbavare un po' ma poi sembrava ok. Vorrei averlo preso più sul serio. Penso che faccia qualcosa al cuore in alcuni gatti e potrebbero volerci anche un paio di mesi per uccidere il gatto. Uso pochissimi medicinali per le pulci. Ho letto che in alcuni casi potrebbe aumentare la pressione sanguigna e forse causare danni al cuore. Ho anche usato una porzione di una dose su un gatto con insufficienza renale cronica di 15 anni e questo ha reso i suoi reni più difficili per un po', ma poi è migliorata un po' per un po' e alla fine l'ho fatta sopprimere. I veterinari si sono comportati come se la medicina delle pulci fosse ciò di cui aveva bisogno. Le ho messo solo poche gocce sulla schiena e l'ha colpita molto. Ad ogni modo, cosa ne pensi della possibilità che causi infarti e/o insufficienza un paio di mesi dopo l'applicazione? Sono sicuro che ci sono gatti là fuori che hanno un'insufficienza cardiaca prima. Questi sono i primi due anni che uso Revolution. Ho sempre avuto gatti per 35 anni e questi sono i primi due anni che ho avuto attacchi di cuore. Se quello che penso è vero, tanti gatti stanno morendo di malattie cardiache che non sono nemmeno riconosciute come correlate alla droga. Sono passato dalla prima linea perché non funzionava più così bene e perché penso che provochi il cancro negli animali domestici. Sembrava che i miei gatti fossero morti di cancro più di quanto avrebbero dovuto quando l'ho usato. Sbaglio a pensare questo alla Rivoluzione?

I switched from MultiAdvantage to Revolution mainly due to price...having 12 cats to treat. Never had a reaction on any of the cats with the Advantage. The vet gave me two large doses of Revolution for dogs along with a syringe marked for a cat dose. I used the Revolution for two months on my cats and now my 12 year old Maine Coon cat is dying. Taken him twice to the vet and all they did was give him a shot for pain and one to stimulate his appetite. I failed to notice the change in his usual Tigger self and now feel it was due to the use of Revolution. All my cats are strictly indoor cats but one who only goes outside when I am at home and outside with her. None of the other cats have shown adverse reactions but I am not going to take any more chances. The death of Tigger is just too much...he was my best bud!

Check ehere you applied it first. If there is an slkerguc reaction the area you applied it will be red and irritated and your dog will have little bumps called hives. However if your dog also has fleas the revolution will start killing them making them twitch around and that can also be why your dog is itchy.

I applied the small dose Revolution to my 10 yr. old Yorkie one week ago. The day after I applied it her little 8lb body looked swollen and she seems to be in pain when she walks. She has always had allergies and will cough up drainage but since applying the Revolution her cough is different, almost painful for her and more often than normal. She shakes a lot like she does when she is in pain. It has been a week since I applied the Revolution and she is still having same issues. Has this happened to anyone's little angel and if so what can I do to help her?

Hi Kim, I know you wrote your message some time ago but how did it end up with your Yorkie? Are you still using the product? I'm considering purchasing Revolution for my 13yr old Yorkie she very small (just under 2kg in weight) and has a problem with ear mites, it's supposed to work on mites. I don't like the idea of applying poison to her skin and waiting for side effects but the mites are bothering her and need to go!

Hi Karen, I know your post is 2 yrs.old, but wondering how it turned out -- I have 3# chi and Vet. wants her put on Revolution and I'm afraid of it.
She scratches her ears a lot, but the Vet said "she's OK" -- I see no drainage or "dirt" but she scratches her ears a lot -- how did you determine your dog had mites? I did put my dog on Rev. one month - she still scratches - and I'm considering not putting it on again.
any help appreciated - joy

I have given my dog 2 doses prior to the one yesterday he was fine with first two. Yesterday I applied revolution to my 84 lb golden retriever and his fur was stiff he was panting terrible and shaking his head from side to side. Rushed to vet who said he was having a reaction this was 6 hrs after first applied. Vet said wash area with soap and water and he gave him prednisone and cortisone shot. Now dog has to be on prednisone for 2weeks. Has anyone else's dog gone through this?

Dan, my 16 lb Miniature Pinscher is having a similar reaction to your dog after I gave him a dose of Revolution a week ago. He has had constant head tremors for the entire week. How is your dog doing now? Did he recover?

È una REAZIONE ALLERGICA. Che tu ci creda o no, gli animali possono avere reazioni allergiche 2 farmaci proprio come fanno gli umani. Basta lavarlo via con il sapone per piatti Dawn e acqua tiepida e puoi dare anche Benadryl per evitare di dover andare dal veterinario e avere un conto pesante per una reazione allergica che può essere facilmente curata a casa

It's not medication. Medicine treats the patient. It's a pesticide that targets a parasite. It's a tough decision - get rid of the fleas to prevent possible disease but at risk of causing harm to your pet. And no one really explains the chances of disease vs pesticide reaction. Though the fleas can get so bad that it can definitely be a quality of life issue for everyone in the family. Natural remedies can be just as dangerous since many are essential oils that cats can't break down in the body, meaning they are toxic to their organs. There's got to be a better way. Right now topical treatments are a necessary evil. I usually wait until there is evidence of fleas then treat my cats.

Our 7 mo. old puppy has had Revolution since his first treatment with the breeder efore we brought him home at 8 weeks, He is now 23 lbs and the Revolution dosage is for 20.1-40 lb. dogs. we gave him the reatment and he has been lethargic, panting and just plain mopey, dopey and listless...I'm hoping today is a better day.
what do y'all do about the large difference in weights for the RX?

Ho messo Revolution su 2 dei miei gatti 2 settimane fa. Uno sembra a posto. L'altro ha una vasta area di capelli sul fianco e sulla pancia che apparentemente è stata masticata/leccata ??? spento. Questa è la seconda volta che le succede. Il primo è stato quando abbiamo introdotto un nuovo gatto in casa. Ho pensato che fosse una reazione nervosa. Ora, sospetto che possa avere qualcosa a che fare con Revolution. La caduta dei capelli non è vicina a dove è andata l'applicazione del farmaco. Non ho intenzione di utilizzare nuovamente il prodotto.

My cat has had a very similar reaction, and I have wondered if it was because of the Revolution. She has been to the vet several times. Flea and environmental allergies have been ruled out. The vet does want to do a food trial to see if she is allergic to a particular food. With no change in her diet since she was a kitten, what I have noticed is this happens, her hair begins to grow back, then with the next treatment she goes through the same thing again. I am hoping someone will address this issue as I am sure Vicky would love an answer as much as I do!

My cat is also losing hair and seems to be. Over grooming and itchy since giving stronghold blue (same as revolution) 3 weeks ago. Since this is a monthly treatment, I'm hoping things start getting better at the end of the month. I'm not giving him this again.

Vicki if the hair loss os NOT near the location of the revolution then its obviously and apparently NOT from the Revolution. Hair loss at the site can happen and as long as the skin isnt red or inflamed they will be fine and the hair will grow back. But hair loss happens right where you apply the dose..not in a completely different spot on the animal. Lol

Are you sure about that, Maureen? I adopted a stray cat who has lung worms and the Vet gave a dose of Revolution between his shoulder blades, and told me to give him another dose higher up on his neck 2 days later. Not only does he have hair loss at the two sites, but also a big patch missing on the side of his neck and on his side. None of the spots are red or itchy, I have not seen him scratch at all yet has 4 bald spots. Just wondering if you are some kind of expert or that's just your assumption. My Vet says it IS from the Revolution.

Ho fatto la rivoluzione della mia gatta di 6 mesi tre giorni fa.. poche ore dopo aver somministrato il medicinale antipulci, ha iniziato a vomitare ogni dove e poi non voleva mangiare, quando beveva acqua, vomitava.. Dopo due giorni ho preso. la sua schiena dal veterinario. Hanno lavato il sito di applicazione, le hanno somministrato una flebo, un'iniezione per la nausea e un'altra iniezione.. hanno detto di portarla a casa e vedere se qualcosa cambia rispetto alla norma. Ora sta mangiando, ma dopo continua a vomitare. Quindi ovviamente ora vogliono che torni per radiografie e analisi del sangue. La mia gatta xenia è sana e ancora giocherellona..non riesce a far andare giù nulla. Non userò MAI più la rivoluzione.

My 12 year old Himalayan never had trouble with frontline, advantage, revolution, in his history but now that he is on daily med for thyroid problems, and I gave him revolution yesterday, today he is not eating and is lethargic. I washed the site as advised by the vet. I am worried that he inadvertently ingested some of the liquid because the brush became contaminated as I brush his neck then brush his chest. His hair is so long he needs constant brushing. I immediately put the brushes in soapy water now and will never use revolution again!!!

I applied Revolution two my year old cats for the first time. The cat that goes outdoors often had no reactions. The cat that stays indoors possible had a reaction. I didn't put two and two together until after the fact. A few days after the application she acted sick. We found vomit (presumably the sick cat) and she laid around with no energy acting sick. She drank water and ate food but just laid in one spot all day. a few days later when she started to act well i noticed a big scab on her neck around where i put the application (it could have been the exact spot but i really do not remember). what would be a good alternative Med for heartworm?

I applied Revolution to both of my cats twice. They are both 1 year old. The first time I applied the revolution on them, the male had developed cold-like symptoms with sneezing, watering eyes and nose but I figured it was probably from the vaccination he received through his nose while at the vet. The second time I gave Revolution to both of my cats, the cats both fought as hard as possible to not have it applied to them. The day after I applied it to the male, he developed a bald spot in the exact same spot behind his neck/between his should blades that the Advantage was applied. This spot was white at first, then turned bright red, then bloody and eventually scabbed and would keep on going through bloody and scabby phases.The spot kept itching him for weeks and he eventually developed another bald spot next to the original one. It was terrible because for weeks the scab would get scratched off and then become a bloody bald spot and took a long time to heal. He seems to be much better now but I was scarred that the bloody spot would eventually get infected due to his consistent scratching. Now I need to find a new flea medication that he doesn't have such a painful and irritating allergic reaction to.

I put revolution on my 2 cats in Aug. 5 weeks later they were itching again so I tried advantage 11. A day after the advantage I found scabs on my cats where I had put the revolution! I had no idea both my babies were burned from the revolution! I put it between the shoulder blades as directed & that's where they both were burned. The advantage is suppose to go at the base of the skull. It was fine with no recactions. I will never use revolution again. I'm sick about what happened to them

Ho comprato Revolution e l'ho applicato ai miei due gatti per la prima volta la scorsa settimana. Uno dei miei gatti ha 15 anni e l'altro ha 8 anni. Entrambi sono molto sani per la loro età e hanno all'incirca lo stesso peso: dai o prendi una sterlina o due. Ho usato la dose raccomandata su entrambi i gatti la stessa notte. È passata una settimana da quella notte e ho notato due reazioni molto diverse da ogni gatto. Il mio gatto di 15 anni si comporta benissimo - nessun sintomo di alcun tipo. Il mio bambino di 8 anni, d'altra parte, si è comportato in modo molto letargico da quando è successo. Ho notato un punto calvo in cui è stata applicata anche l'applicazione, quindi ho chiamato il mio veterinario. Ha detto che potrebbe essere un effetto collaterale e portarlo dentro, ma costerebbe $ 44. Ho speso più di $ 100 per la medicina delle pulci che lo ha fatto ammalare ... le ho detto che avrei aspettato un altro paio di giorni e avrei visto come si comporta. Finora non l'ho visto vomitare o avere convulsioni. Si comporta solo in modo molto letargico... in realtà non fa altro che sdraiarsi e dormire tutto il giorno. Inoltre non mangia vicino quanto fa normalmente. Ho comprato del cibo morbido per cercare di farlo mangiare, poiché mangiano principalmente cibo duro. Mangia, ma solo piccole porzioni. La scorsa notte sono andato nella mia stanza e lui era sdraiato sotto il letto - non lo fa mai. Non sono sicuro di cosa fare... odio vederlo così e mi preoccupa. Ho letto i commenti e molte persone hanno detto che il veterinario non ha fatto la differenza. Non so se dovrei continuare a vedere come si comporta e sperare che migliori, o andare dal veterinario. So che non lo userò mai più su di lui. Per favore, per chiunque abbia avuto a che fare con questo... quanto tempo ci vuole prima che il gatto guarisca? Qualsiasi altra intuizione sarebbe molto apprezzata!!!

Uso Revolution per i miei due cani e 7 gatti da molti anni senza problemi. Prima di questo, abbiamo utilizzato il vantaggio perché ho lavorato con i documenti come mamma adottiva e il vantaggio è molto più facile da acquistare, dividere e utilizzare su animali più giovani. Ma ho sempre scoperto che gli animali diventavano leggermente letargici con l'avvge... E la sua aspettativa di vita diminuisce ogni volta che l'animale nuota o viene fatto il bagno. Generalmente, con la rivoluzione, è la pulce/zecca/verme più sicura disponibile, purché venga applicata correttamente e non sulla pelle rotta. Se il tuo animale ha cattive pulci e si è graffiato - il componente del vettore - una piccola quantità di alcol può causare irritazione alla pelle e il pelo cadrà. Probabilmente, l'animale si stava graffiando e all'inizio aveva un'irritazione cutanea sottostante.... È difficile vedere le piccole eruzioni cutanee finché non si irritano e poi vedi possibili croste e perdita di capelli che guariranno finché rimani su una buona pulce rimediare e non essere reinfestato :). Ho scoperto che se c'è una reazione alla rivoluzione - è entro poche ore dall'assorbimento del medicinale - poiché entro 2 ore è sicuro toccare il tuo animale domestico. Se sono trascorsi giorni o settimane - potresti confondere i farmaci - il vantaggio può essere lavato via in qualsiasi momento e renderlo meno efficace. I marchi topici del negozio di animali (sul collo) non dovrebbero MAI essere acquistati - e so che le persone si arrabbieranno con me e diranno che funziona senza effetti collaterali per loro (ottimo per loro) ma ottieni sempre trattamenti per le pulci dal tuo veterinario. E infine, semplicemente, i sintomi possono essere il risultato dell'assenza di pulci. Anemia, graffi e croste da vecchi morsi mentre guariscono. Immagina di avere migliaia di queste creature su di te che succhiano il tuo sangue e sangue più piccolo senza animali? saresti stanco anche tu!!! Infine, la rivoluzione è efficace al 99% nell'uccidere pulci, larve e uova sugli animali e nell'ambiente il vantaggio uccide solo gli adulti delle pulci che MORDISCONO il tuo bambino in modo che continuino a soffrire mentre ti sbarazzi delle pulci. Tu fai i conti. La rivoluzione è un buon prodotto: il vantaggio è un'ottima seconda scelta. Mai comprare dal negozio di animali non è la stessa cosa! E sì, ci sono sempre delle eccezioni, proprio come una persona può essere allergica alla penicillina: un cane può essere sensibile a un rimedio contro le pulci ma non scartarlo al primo tentativo. Il tuo primo mese potrebbe essere una reazione al morso delle pulci o un errore di applicazione: chiedi aiuto al tuo veterinario. Buona fortuna e amore a tutti i cuccioli di pelo là fuori!!!!

I gave revolution to my 1yr old cat about month and a half ago and he developed a staggering walk and does not hold his tail up. I am hoping that he will get better as it ears off he walks a tad bit better looks like a raccoon sometimes he has no control over pooping and peeing. His sister was given it at 9 months old she started having seizures and had to be put to sleep I ask at that time if it was the revolution or the vaccine she was given the vet said no but I had not been having problems with her like that and the day before at her appointment was told how healthy she look. Does anyone know when and if this will wear off or is his condition permanent?

Ho dato il mio Maine Coon Revolution di 13 anni e mezzo il sabato. 11 aprile. Sembrava stare bene quella notte. Ho lavorato tutto il fine settimana ma sono venuto a controllare i miei gatti diverse volte. Sono tornato a casa lunedì mattina e devo partire per un'emergenza familiare. Non l'ho notato comportarsi in modo strano, ma era mattina presto e stava dormendo. Sono tornato a casa giovedì sera e barcollava con le zampe posteriori. Semplicemente non sembravano funzionare. Lo portò dal veterinario, gli fu detto che aveva un disco danneggiato e forse problemi neurologici. È costantemente peggiorato. Non mangerei né berrei. Ho provato a dargli fluidi subq, ma ha perso ogni sensibilità alle zampe anteriori e poi le gambe posteriori hanno fallito. Ho dovuto tenerlo nella lettiera. Diversi viaggi dal veterinario per radiografie e analisi del sangue e gli è stato detto che avrebbe potuto avere un ictus e stava lanciando coaguli. Ho dovuto farlo addormentare il 12 maggio, non riusciva a tenere la testa alta e non sentiva affatto le zampe. Stava bene prima che provassi quella dose di Revolution. Ho sempre usato Avantage, ma il mio veterinario ha detto che l'hanno lasciato cadere perché erano la stessa cosa e non volevano portarli entrambi. Non ho fatto la connessione prima, ma ora ho iniziato a chiedermi se fosse quella dose di Rivoluzione. Non lo userò più sugli altri miei gatti anche se non sembravano essere stati influenzati da quella prima dose. Non posso correre questo rischio.

Ho bisogno di chiarire il mio post. Era venerdì 11 aprile 2015, non sabato. Inoltre, al mio gatto è stata somministrata un'iniezione di prednisone. Quando l'ho portato indietro qualche settimana dopo, non stava migliorando, gli è stato somministrato prednisone per via endovenosa e mandato a casa con prednisone liquido per 10 giorni e a giorni alterni per altri 10 giorni. Inutile dire che non ha aiutato e le successive visite veterinarie non hanno aiutato. Fu addormentato il 12 maggio.

Experienced the same effect of Revolution on my 12 year old Maine Coon, Tigger. I didn't make the connection to Revolution until I looked on my dry erase board as to when I applied it to my cats. I had always used MultiAdvantage but it gets expensive when treating 12 cats! The vet said I could get two large canine doses and use a metered syringe for the cats...I have only used Revolution twice and now realize that is when Tigger's usual behavior changed. He stopped jumping into the bed at night, stopped playing, laid around a lot more. I just realized it too late.

La mia femmina di 5 anni ha passato tutta l'estate scorsa a scavarsi il naso e le orecchie. Aveva piaghe e croste sul naso, sulle orecchie e persino sulla pancia. Il veterinario ha inviato una biopsia della pelle che stava reagendo. I risultati sono tornati come una reazione allergica. Non ho mai nemmeno pensato che la reazione potesse essere dovuta alla rivoluzione fino a questa primavera quando l'ho usato su di lei per la prima volta (non glielo do in inverno dato che non trascorre molto tempo fuori). Ha resistito fortemente all'applicazione (e non c'era pelle rotta). Sembrava anche molto sensibile quando l'ho toccata lì per il resto della settimana. Così ho iniziato a cercare su Google Revolution e ora intendo starne lontano e vedere se la sua pelle si schiarisce. Sono pronto per qualsiasi cosa olistica: le pulci sono meglio che torturarla con questo farmaco!

I really feel like I should share my story in case anybody is in the same situation. I read this blog, and many others, looking for adverse side effects of Revolution for my 10 week old kitten that we just adopted. She had mites. We took her into a holistic plus conventional vet clinic for a "kitten checkup" after I discovered mites in her ears. She was giving a single spot on applicaton of Revolution (so was my other cat, who had contracted them after just a few days, who is a perfectly healthy 1 year old cat that eats a raw food diet.) My kitten was treated on June 10/2015. After just a couple of days I noticed my precious little kitten had totally stopped eating, only slept, couldn't stand on her feet and was shaking profusely. I let this slide for 1.5 days and then took her to the vet. She wouldn't even smell food that was put in front of her. She would only sit and then lay down when stood up on all fours by me. The vet took her within an hours notice and said she had high fever, dehydration and a 'gassy tummy'. She was treated with a subcutaneous saline solution. We were given a homeopathic remedy of probiotics, aloe vera and slippery elm. That night I thought we were going to lose her. Her hind legs fell limp. She had a blank stare and no coordination. I force fed my kitten the medication I was given by the vet, plus honey water mixture, and a kitten formula that I got from a pet store. I really truly believe that my kitten was poisoned by Revolution. The adverse side effects of .05% of cats in the approved studies were her symptoms exactly. I nursed her with her medicine, milk, and honey water for two days straight, every chance I got, She regained strength in her hind legs. She even ate yesterday and today. I think my little kitten is going to pull through. Please, anybody who thinks their kitten or dog is having an adverse side effect of revolution, tell your vet right away and nurse your poor pet back to health. I read too many stories last night and the night before while I thought my baby kitten was dying in my arms to even consider anything else. PLEASE! treat your pet with saline solition, a probiotic, some kind of electrolyte solution (like honey and water) and force FEED them until they start eating again! This experience was horrific, I prayed and watched my poor kitten for 3 days now all night long and force fed her things that would help. Please, share my story. My kitten is pulling through. If your pet is not puling through try these remedies. I have never posted stuff like this but I feel like my story should be shared and everyone should know the potential risks of Revoluation.

My cat of 9 years has been treated with reveolution a month ago, I took her back and they treated her with cortisone, that did not help much with the swelling and itching and she still has not recovered with hormonal treatment and antibiotics, the surrounding head area from her eyes to her ears and around the neck look like burnt marks and turned into scabs that just does not want to subside with all the treatment and I am desparate to find a solution other
than cortisone treatment. I so think that the compony that produce this product should really go back to the drawingboard as I see a lot of people whos dearest best friend suffer at their neglect. surely somebody has complained to this compony already.

Ho usato Revolution sul mio Shih Tzu di due anni il sabato. 6/20 e domenica pomeriggio era letargica. Lunedì ha iniziato a vomitare tutto il cibo e ha perso alcune feci. Martedì l'ho portata dal veterinario ma non ha scelto di spendere mille dollari solo per fare alcuni test. Quindi è mercoledì ed è ancora molto letargica e non mangia. Le ho fatto bere un po' d'acqua mettendola prima sulle dita e lasciandola leccare in quel modo. Mi sento così male che le sia successo questo. Ora sta vomitando di nuovo dopo quella piccola quantità d'acqua.

We began feeding a cat that just showed up to our house. We noticed it was developing a crusty rash. Similar to what our own cat had a year ago. So we gave this street cat a dose of revolution. Since it worked for our cat. We noticed that it was a bit skinny (under fed). It loved the cat food we gave it for the past days. The following morning, the cat is just laying there in the sun. It will drink very little water. No food. I picked it up and placed it under a shady tree and placed water next to it. I feel HORRIBLE. I wanted to do something good for a street cat that was very friendly. Now I may have just ruined his life.

Ho 12 gatti. Ieri sono andato dal veterinario con un cane allergico ai morsi delle pulci. Il veterinario mi ha suggerito di usare Revolution su tutti i gatti perché stanno principalmente all'aperto e Nexcare sui cani. Su 12 gatti, solo uno ha un problema ed è quello che ha la reazione allergica ai morsi delle pulci insieme al cane. Beve e mangia ma ha vomitato un paio di volte. Ho somministrato tutti i gatti contemporaneamente e 24 ore dopo, sembrano tutti a posto tranne uno. Ho un gatto di 17 anni e uno di 2, quindi è una vasta gamma. Spero che vadano bene perché non ho mai usato questo prodotto.

Salve, abbiamo sempre usato il Drontal per i vermi e il Advantage per le pulci, MAI avuto pulci o vermi da affrontare. Poi ci hanno presentato Milbemax e Revolution, le pulci continuano, NON muoiono e le uova continuano a schiudersi a ondate. Il mio gattino di 6 mesi dopo aver ricevuto Milbemax e Revolution, è malato, letargico, non vuole mangiare, cerca sempre di vomitare, imbavaglia, non vuole giocare, solo dormire. Ha un cattivo equilibrio e a volte cade. Questi sono 2 farmaci cattivi e dovrebbero essere tolti dal mercato, fanno ammalare gli animali e questi farmaci NON FUNZIONANO su pulci o vermi. Non userò MAI più questi farmaci, userò Drontal e Advantage, molto sicuri, NON ho MAI avuto problemi in tutti gli anni in cui abbiamo avuto animali. L'azienda che produce Advantage e Drontal è presente per MEGA! ANNI! ed è un'AZIENDA MOLTO AFFIDABILE! E i farmaci funzionano GRANDI E SICURI! per animali domestici.

I adopted a Pomeranian rescued from a puppy mill in Alabama. I have had Lilly since October 3rd. I noticed that she was shaking her body like she had just had a bath and brought her to the vet two weeks ago where she was treated with Revolution because the vet said she had ear mites. I brought her back to the vet tonight as recommended for a follow-up and they suggested a repeat dose, even though there weren't any live ear mites. I was a little worried since she is 13 pounds and but I let them administer a second dose at about 6:00 pm on Tuesday, December 8th because you have to trust your vet or there is no point going to them. At about 11:30 pm, Lilly's head started shaking back and forth. She didn't seem upset and the only thing I knew that was different was the dose of Revolution. Since my vet was already closed, I called the closest 24 hour animal hospital in the area and they said to watch her tonight and if it didn't stop or if she developed new symptoms, to bring her in or to my vet in the morning. Over the past 2 hours, I did a lot of research and found what she was experiencing is called "idiopathic head tremors" and saw videos of dogs with the same symptoms. The general information I found said to stay calm and the dog would not be upset and to try to distract the dog with toys or treats. I found that these symptoms often occurred after dogs were treated with heart worm medication. It is now after 1:30 am on December 9th and it has been happening on and off for 2 hours and sometimes wakes her up. I would be more alarmed but she even got up and ate while it was happening, and she is now sleeping next to me. I see that several people wrote with the same symptoms so I decided to share this. Thanks!

Sto dando Revolution alla mia gatta di 15 anni ormai da un coupé, ma dopo avergliela data stasera, ha vomitato. Deve essere allattata manualmente ma non è venuta da me per le poppate programmate come fa normalmente. Quando la cerco, mangia il suo cibo umido e beve acqua. La sto ancora guardando per vedere se questo comportamento continua fino a domani. Qualcun altro ha avuto questa esperienza di un gatto che sviluppa improvvisamente una reazione?

I would get her checked out at the vet if I were you. It may be totally unrelated to Revolution. Cats of that age (like my Molly, about 15-16 years old) often develop some form of renal failure which can cause significant changes in their appetite. Especially if it goes hand-in-hand with thyroid issues. Kidney disease, thyroid problems, and diabetes are the trio of old-age problems that nearly all cats are likely to develop, with renal failure being the most common cause of death for elderly kitties. Regardless of if Revolution is the cause of the current symptoms or not, it's probably wise to have her checked for those issues.

I adopted a 6 month old cat last September and over the winter she developed some fleas. She also had some roundworms in her gut, which I discovered when she expelled some worms into the litterbox. It made sense, then, to try one treatment that could deal with both problems.
I had tried a cheaper flea treatment before which hadn't done much of anything (to the fleas OR the cat) but I did notice with the cheap one, that my little Smokey is flexible enough to twist right around and lick whatever you put between her shoulderblades. So when I got the Revolution, I put it in a spot I know she couldn't lick directly: between and slightly behind her ears. She's been totally fine with no reactions to the medicine (aside from freaking out when it was applied, but that was because it was a wet liquid and she hates wet!)
If your kitty is normally very good at contorting into odd positions, then I advise placing your flea medicine higher than the shoulderblades. Some of the symptoms people see could be from kitty accidentally ingesting the medicine when you're not looking!

If you need help treating fleas in the home, I recommend diatomaceous earth. It's a kind of soft rock crumbled into powder form (perfect for all you fans of natural remedies) and has properties that basically turn any insect's exoskeleton into a sieve. Your fleas (and other crawling insects) will die of dehydration as their bodies can no longer retain moisture, and it's one of the few things that works on the robust pupa stage of the flea life cycle.

Been giving my cats Revolution for several years now and have had no issues. Other flea treatments simply do not work. However, my late stepdad's car, who I "inherited", has shown issues with stomach upset. She is OK, but I was wondering if there is a recommended product for senior cats.

Tutti i trattamenti contro le pulci attaccano il sistema nervoso e riproduttivo delle pulci. Se, come con i farmaci per uso umano, un individuo ha una predisposizione affinché quel medicinale causi una reazione neurologica avversa, lo farà. Tieni presente che non è lo stesso per tutti gli animali e tutti i trattamenti contro le pulci, anche le pillole, comportano rischi intrinseci. Informati in anticipo, osserva i segnali e prendi le misure appropriate. Non è solo Revolution che può causare effetti negativi sul tuo animale, ma è anche ogni medicinale o prodotto antipulci disponibile. L'aspirina può causare morti umane, ma le persone la prendono ancora per il mal di testa.

Uso Revolution da anni senza problemi, ma questo mese scorso uno dei miei gatti di 13 anni ha perso i capelli e sembrava essersi bruciato nel punto dell'applicazione. Anche lui è stato letargico. L'ho applicato alla mia gattina di 14 anni la scorsa settimana e sabato mattina abbiamo dovuto metterla giù. Ha iniziato ad avere una respirazione molto affannosa e aveva liquido che circondava i suoi polmoni. Non c'era niente che si potesse fare. Ho detto al veterinario che avevo applicato Revolution una settimana prima, ma lei pensava che non avesse nulla a che fare con questo. Mi sento così in colpa. Penso di aver ucciso la mia dolce ragazza applicando Revolution.

Our new 8 week old kitten that we purchased from the Animal House in Morgantown died 5 hrs after being given revolution. Prior to the treatment she was flea infested and had been treated for worms. The meds for worms seemed to be well tolerated. But her stools were loose and became watery. They firmed up after the worm treatment for a day or so. After the vet checked the stool and saw there were no parasites, we started giving her probiotic which she seemed to tolerate ok. I woke up at 4 am last night and her the kitten calling out downstairs. I found her at the bottom of the stairs and her body was limp. She was still able to focus her eyes on me but her breathing was very shallow. Within 30 mins her eyes glazed over and her breathing was barely perceptible punctuated with sharp breaths and then gasping breaths. I called the emergency vet at 5 am but there was nothing they could recommend I do. I knew we were going to lose her. I stayed with her trying to comfort her and let her know she was not alone. She had her last breath about 6 am. I have never lost a kitten. I have no doubt that there was a connection between her death and the revolution. She had been weakened by her loss of appetite and loose stools. Now I have to tell my daughter who is away at camp. Echo was her kitten. So very sad!

I have used Revolution for years. My previous dog developed lymphoma and died. I did not connect it to the Revolution treatments.
My 3 year old collie cross started having episodes when we played ball last summer. I believed it to be heat exhaustion. Then she started having seizures. All the bloodwork was normal. I don't give her the Revolution over the winter and she had no episodes.
I gave her the first dose 2 weeks ago and she has already had 3 episodes of staggering, panting and on 1 occasion fainted.
I will not be using Revolution again and will see if these episodes stop.

Ho preso i miei 11 anni. gatto maschio da controllare mentre andava alla padella del gatto spesso n seduto lì con piccole quantità di urina quando andava, quindi pensava che potesse avere un blocco urinario, calcoli, o? Hanno testato la sua urina e hanno detto che aveva un'infezione del tratto urinario, quindi gli hanno fatto un'iniezione di antibiotici. Hanno anche suggerito un trattamento Revolution mentre non aveva molte pulci ma mostrava la forfora delle pulci. Ho usato il vantaggio negli ultimi mesi, ma molti dicono che le pulci ne sono diventate immuni. Dopo alcuni giorni a casa era sdraiato e nascosto, poi ha smesso di mangiare. Pensavo stesse solo guarendo dall'infezione delle vie urinarie, ma poi ha iniziato a starnutire cosa che non aveva mai fatto prima e ha persino smesso di bere acqua e stava diventando debole e svogliato. Per farla breve, l'ho riportato dal veterinario ma ha iniziato a fallire ancora di più e ho dovuto farlo addormentare. Penso che la Rivoluzione lo abbia colpito in modo negativo, oltre al fatto che aveva già un'infezione alle vie urinarie. Anche il mio altro maschio di 16 anni ha avuto la rivoluzione dal veterinario mentre era lì per un controllo e sta bene, nessuna reazione negativa. Ho sentito parlare bene e male di Revolution e alcune delle storie ti spaventerebbero dall'usare qualsiasi cosa. La cosa migliore è discuterne con il veterinario e considerare la salute di base dell'animale e, o, altri problemi prima di introdurre un nuovo prodotto per le pulci. Pulisci l'ambiente e prova a pettinarti e pulirlo spesso. Inoltre, se riesci a infilare l'aglio nel cibo aiuta a respingere le pulci, così come alcune formule di aromaterapia per uno spritz naturale sul pelo e per curare la lettiera. Fai attenzione, poiché alcuni oli possono anche essere dannosi, quindi fai i compiti prima dell'uso. Ogni animale è diverso, proprio come noi umani reagiamo tutti in modo diverso a vari farmaci e trattamenti. Ricerca in anticipo per dare al tuo animale domestico tutte le buone possibilità di ottenere un buon risultato. Se lo meritano. Spero che questo sia stato utile in qualche modo.

I gave Revolution to my kittens after seeing worms in their stool. I have 2 kittens both from different parents, female 7 month old and male 4 months old. My vet suggested Revolution couple of times, and I said I will do my research and let you know. Finally because of the round worm discovery I decided to go with it after I had done my research and knew more about the product then the person selling it to me. I applied as instructed also watched video on youtube. Both of them didn't like it for first 30 mins kept trying to reach it to lick it and scratch it, however I had to keep them separate as well so they would not lick it off each other. After an hour or so they were back to normal. I have not noticed any behavioural change, except my 4 month old male has upset stomach and can't imagine that tiny thing can fart such a pungent smell. Its been a week, went back to Vet to for his follow up shots, and Vet suggested to give them Second dose of revolution after a week to make sure all the worms have been killed,
O-o ???
I wasn't sure if this has been done before, but something about that doesn't feel right to me, my regular Vet is on vacation will wait for his opinion. In my personal opinion we as pet owner are emotional about our pets, which are source of income for vets. They may seem like they care for animals and are animal lovers, maybe that once drove them to become a vet but its not why they are still vets, I mean they don't ask if we could do tests, no no no they tell you we are going to do all these useless tests and charge you for every tiny little thing... I don't mind spending money if it is worth it, but most of the time, they are just after making extra buck at the cost of your pets life. The way they handle them, the way they are giving them medicines without any second thought. As human body goes through up and downs, we sometimes require medicine and sometimes don't, our bodies can recover from few things, same with animals they have been living for long time as well, they know their bodies and have natural instincts. The way these vet describe one small decease is like it will be end of entire cat nation. My kittens never scratch themselves, but started to after visit to Vet, its like you car need a bulb change after it came from mechanic it needs 5 more things fixed.
Will keep you posted if there is any change in their behaviour or health, but I won't be applying it twice, its not like antibiotics that you take double dose first time.

p.s. I don't think pet owners should pay out of their pocket for their pets allergic reaction to the meds especially when it leaves them with pain or worse.

Good Luck

My vet recommended resolution for my 8 week old kitten and then a second dose 2 weeks later. My kitten ended up not being able to eat or drink and had mouth ulcers. He ended up on pain medication and an antibiotic. The vet does not think its from the revolution. They wont ever admit to that! Revolution is neurological and very dangerous, there is no antidote. I dont know if my kitten will make it or not. Oh the vet also said it could ne the breed of my cat thats csusing the sickness! What an insult to my intelligence.

Oh man this is why I don't believe these Vets or Doctors(speaking from personal experience). I hope your kitty feels better soon, I know they do say they have tested it on different cat breeds but few might be allergic to it, if they have tested on the cats wouldn't they know which breed is allergic to it.
I never called my other Vet, something about giving 2 doses in a month, just didn't set right with me. They were ok after one dose, although the area where I applied the medicine had very pungent smell after day or two. I checked their skin and it was okay there was no rash or anything but only on one(male) of them it smelled weird.

They can't blame Revolution just like our doctors they do also get incentives to sell their drugs more then others, now a day its all about money not about health.

Keep us posted about your kitten.

Good luck

I took my cat to the vet yesterday, she had what appeared to be "flea droppings" (little black specs that turn red when they hit water) but no active fleas. I can't find any in the house either, so the vet suggested a precautionary Revolution treatment. I wish I would have done research before I agreed. Since then she has been very lethargic.
I woke up last night to her sleeping on a pillow.. face down...I couldn't hear or feel her breathing. I freaked out and had to shake her awake, she then tried to purr after a while and started coughing like she was trying to get a hairball out. The following morning she refuses to eat or drink and just lies on the floor. I am very nervous after reading this forum!
I called the vet and they told me that lethargy is not a side affect of this drug...which is clearly NOT true. She also has fur and skin discoloration. This treatment is NOT WORTH WHAT HAPPENS TO YOUR PET!!

If after administering flea medication or if your pet acts differently after bathed in a flea and/or medicated shampoo BATHE them immediately with dish soap. Blue Dawn dish soap is preferred but any will do to remove the product and rinse your pet thoroughly. Rinse them twice as long as you normally would. If you gave your pet an oral medication and they are acting differently please contact your veterinarian immediately.

Avevo un gatto molto sano, usciva raramente e se lo faceva era solo nel cortile. Abbiamo avuto un problema con Flees, stavo usando Advantage che sembrava helo ma il veterinario ha consigliato le rivoluzioni. In questo momento abbiamo avuto 2 gatti e un cane che erano tutti su di esso. Una volta passati a Revolution, il mio gatto ha avuto una reazione cutanea che non ho notato subito, quindi ho smesso di usarlo su tutti i miei animali domestici. Il mio gatto ha iniziato a comportarsi in modo diverso e ha avuto enormi noduli sul collo, vicino a dove è stato somministrato il medicinale, si scopre che aveva avuto un linfoma che si dice sia vicino ad altri gatti o fuori. Trovo che fosse nella stessa area della Rivoluzione, potrebbe essere questo che ha causato questo? Non lo so, ma ho dovuto metterla giù il mese scorso e non posso fare a meno di chiedermi. Mi manca il mio gattino però

Its straight up poison. Two of my dogs started having seizures after we switched to Revolution instead of Heartguard. It was a delayed response and the seizures were a couple months later. The blood work came back normal and they were labeled as idiopathic epilepsy. Didn't give it to them for a few years after that and they never had seizures again. This year we gave it to them once at the end of heartworm season and sure enough both had seizures a couple months later. Coincidence? I don't think so! This is a neurotoxin and not all dogs have the ability to rid it from the system without suffering side effects (immediate or delayed).

A stray was mauled by a dog owner who doesn;'t leash.Took stray to my vet, he had to have surgery so he stayed there a week. I mentioned flea problem with my kitties at home. Vet recommended Revlution. I gave one kitty her dose, 5 days later, I got another four kitties their dose. The first kitty was lethargic until day 5 when her kidney was giving out, per a vet visit. He said feline leukemia. I put her down after a wonderful afternoon doing all things she loved. Been 3 days since I dosed the four kitties. ALL are lethargic, will not eat, walk, purr, or give me lovings. They best be ok or I will be having a serious convo with my vet. $850 later and possible 5 dead kitties. Will definitely be getting copy of the bloodwork papers on my one kitty who went to heaven on 8/15/17. I love you, forever, Mocha.

The STRAY CAT who had jaw surgery was in a week, so he didn't get a dose of Revolution.

HE IS THE ONLY ONE ACTING NORMAL.

I had been dosing my dog, Sadie, with Revolution since she was 6 months old. In June, 2016 she had her first episode. She lost coordination, couldn't walk, stiffened, then her head began to shake back and forth, she shook from head to toe. After about 2-3 minutes she returned to normal, but she threw up. She had another episode about 2 weeks later, then nothing for 6 months. Then it started again, about once a month. When I took her to the vet, the doctor said she needed to start anti-seizure meds. We both agreed to give it one more month. The following month I gave her the Revolution dose, and she had an episode about 5 hours later. And that's when it hit me. Could it be the Revolution? I spoke to her doctor, and he told me to stop the Revolution. She had a very mild episode about one month following her last dose of Revolution, and hasn't had one since. The moral to this story is, it took ME to figure out that Revolution was causing these episodes. Her doctor said that she is the first case he has seen with this reaction to Revolution. I hesitated to put her on anti-seizure meds because these meds become a life time commitment, and they only treat the symptom. After reading all the entries to this blog, I see that many dogs and cats have horrible reactions to this drug. It should be outlawed.

My lab sharpei mix dog started using Revolution when he was about 5. No problems for 5 years, but this month, starting about a day after I administered his monthly treatment, he had a seizure, grand mal type, legs paralyzed, back reverse arch and stiff. He's had at least 4 more this week. His health has been great, generally, but also just recently he started having trouble climbing stairs, and his energy level is down drastically. I suspected the Revolution, and after reading of similar symptoms here, now I see the pattern, and will never give him another dose. I hope he can recover from this episode.

Like many others my cats have experience discomfort when having Revolution applied (burning, itch, hyperactivity) but I feel like I need to share as I see the effects reaching new highs.. A few months back my three indoor cats were all getting a monthly dose of Revolution (because, who wants fleas right?!) but I stopped due to the prolonged sensitivity and itch it would give one of my cats. Also, one morning a few days after applying Revolution to the cats I woke up with acne-like bumps all over my face and upper body. Nothing I have ever experienced before and that night my "itchy" cat had slept up against my neck - so I stopped Revolution thinking it might have caused this reaction to my skin. Fast forward 6 months, randomly I find one flea on one of my cats and no matter how much I brush I find nothing more than one. So I treat the house with peppermint spray, give all three a Capstar and a dose of Revolution. The itch and jumpiness sets in immediately. However, this time one of my cats doesn't stop scratching. Two months later she is still itching and has big pieces of dander all over her black fur. She even is scratching so much she starts bleeding under her chin. At the same time, I start to develop eczema/acne symptoms again and have to see my dermatologist again. This thing is poisonous to cats AND humans and you will never get the vet to admit that (I tried!)! It's their bread and butter!

PLEASE EVERYONE, stop putting these poisons on your animals. All your pets symptoms are definitely from the flea medication. My vet applied revolution on my perfectly healthy 5 yr. old cat (3 applications) and now my cat is having an allergic and neurological reaction , hyper, agitation, running fits , licking biting , scratching, and losing his fur .
I will never give him any chemicals again. I'm using only natural alternatives going forward, and now I'm detoxing him with a all natural liver cleanse and probiotic and fish oil.

My vet insisted on giving my perfectly healthy cat revolution. 24 hours later same adverse reactions as all of the above people experienced only my poor sweet Ava developed Ataxia, a side effect stated on Revolution's insert. I would find her laying in her litter box as if she tried to go to the bathroom but then couldn't get herself out. The few times I saw her walk - or attempted to - she would take one or two steps and fall over to her side. She lost feeling in her front limbs - I applied the Revolution between her shoulder blades - so its a definite correlation as to why her front limbs lost feeling and she couldn't walk. One week later I found myself at the vet and there was nothing I or the vet could do but euthanize her. JUST two weeks before this incident and never being on Revolution, she had bloodwork, urine analysis, etc. performed and it all came back as perfectly healthy. So why did I have to put her down one week after applying Revolution? It was and is still - the worst event of my life and very difficult to understand and/or deal with. A medication that is supposed to help our animals yet it kills them. I'll never use these types of medications again on my 1 remaining cat and three dogs.

I was worried my kitten had ringworm, and applied the Revolution near what was probably broken skin. It burned her skin deeply, Turing it leathery and still, after which it peeled off almost completely. On the earliest spots her fur is finally returning - but don’t apply near broken skin. She hasn’t had any other bad symptoms thank god, but it’s been weeks and she still has a big bald spot.

My mom's 1 1/2 year old cat was given Revolution a week ago and is now severely anemic and lethargic, won't eat. It is so sad. She is rushing him into the emergency vet now for blood transfusion. So sad the vets won't even consider it being the Revolution, obviously they get a kickback. So my mom has spent well over a thousand dollars with no answer and not knowing if her cat will make it. I am sickened by these pharmaceutical companies.

We just went through a real ordeal with our 2 babies - 10 months old and 9 years old (felines). The little one was treated 3 times, despite us trying to convince the vet it was not working. The older one was treated once and was sick for about 2 weeks. Severely sick and lethargic.
CHANGED VETS, CHANGED MEDICATION - all mite free and healthy now.
Nothing good can be named Revolution.

I feel like I need to comment because I have been using Revolution on both of my cats for years and have never had a problem. Recently, I've found it doesn't work as effectively as before and that's why I was looking it up. But as to any side effects, none. It also used to work better than any other product at getting rid of fleas.

Hi,
Have been splitting dose of bigger vials of Revolution for dogs between my three chihuahua's for several years. Have seen no ill effects, but I agree, something has changed with the formula. Tucker just came from the groomer and was loaded with fleas. I had noted a lot of scratching going on even though they are not due for another dose for another week. Now, I wonder if they have not been protected from heartworms as well.

A lot of these comments and there is so much confusion! I work for a vet for 20 years and they are not trying to push drugs for your pet. First, Revolution is a drug not a chemical, advantage and Frontline and topical products for flea and tick prevention are all insecticide based. They do not enter the bloodstream they stay in the top layer of the skin. Revolution is a heartworm preventative, a single parasitical drug that goes on to kill fleas for the next 30 days. It enters the bloodstream like any drug does. Of course some animals just like some people will have side effects from certain drugs. Have you not heard the commercials on TV followed by a Litany of possible side effects? The important thing is to be aware, and also know there are a wide variety of drugs available to address heartworm. If a animal has a reaction to one type of drug it's advised to use a different type of heartworm drug. Also keep in mind that heartworm is fatal. Heartworm disease is also a very expensive to treat and monthly heartworm prevention is always the better option. So if you feel your vet is trying to push medications on your pet, realize your vet is actually trying to save your pet from getting heartworm disease! Keep in mind that topical flea products sold over the counter are governed by the EPA Not the FDA. Always ask your veterinarian for the best topical flea treatment, veterinarians are knowledgeable about topical flea products that are effective and studied to be safe versus those that are on the Shelf at any Walmart I may not have any safety studies associated with them. Again, pets are individuals as people are individuals, and your pet may fall into the 1% or 2% of the population that may have a specific reaction.

Did anyone have a dog where their nose went from black to pink? This all happened after I applied the one and only treatment to my 1 and 1/2 year old spayed female small dog. I read all the other causes for this, but since the day after Revolution treatment, I noticed the pink on her previously very black nose. Waiting to see if it goes back to black. It's been about a month now.

I reluctantly put this on my large cat. The does was even a hair less than recommended. It burned him. He now has scabs and a half dollar sized bald spot. Shiny bald. It doesn't look like it will grow back. He was a true beauty before Revolution. This is a terrible scar. It even seemed to melt some surrounding fur. It is breaking my heart.

Vet switched us from Frontline to Revolution on 5 year old Border Collie. After 3 months dog started having seizures once a day. After we researched this on the internet we saw many complaints about this product. Bathed the dog with Dawn dish soap to get as much residual product off as we could. Seizures became less frequent and less severe after about 3 weeks. Changed treatment to Seresto collar for fleas/ticks and back to Iverheart Plus for heartworm. As soon as the supply runs out our other Collie is going off this product as well. If you have never witnessed a dog having a bad seizure, you won't want to chance using this product at the recommended dosage. It literally sent my wife off crying to our bedroom on more than one occasion.

I gave my Ragdoll cat Revolution about 1.5 weeks ago. Since then he has lost all the fur on the underside of his leg. Now he is throwing up, lethargic and won’t eat or drink. This happened once before and he had $500 worth of tests to figure out what was wrong, but they couldn’t find anything. Now I know - it’s the Revolution. This product should be taken off the market and someone should sue this company for poisoning our pets.

I have read the anecdotal comments about Revolution, but have not read one post that actually proved Revolution caused any harm. I have used this product for more than 10 years on five different breeds from toy to mastiff size. I have never had a reaction on any of my pets. Like all products, its very important to use the correct dose and to apply it in the area instructed so the pet can't lick it off. Especially cats! It is applied at the base of the neck in front of the shoulder blades, for the express purpose of the pet not being able to lick it. Also not to be used on sick, debilitated or underweight animals. Tests on cats....In safety studies, Revolution was applied at 1, 3, 5, and 10 times the recommended dose to six-week-old kittens with no adverse effects. In dogs... It was administered at 1, 3, 5, and 10 times the recommended dose to six-week-old puppies, and no adverse reactions were observed. Keep in mind this is not just a flea prevention product. It is also a heartworm preventative. Before using the pet should be clear of heartworm, and NO other heartworm product should be used. The active ingredient is a semi-synthetic ivermectin, which has been safely used by Vets on pets, and farmers on cattle, pigs, horses etc, for decades.

You can give me your info till you are blue in the face and I’m going to sit here and stare at the nerve!! I AM a biologist. I took my 14 yr old cat to a new vet to have a check up. Her blood test came back so perfect he was surprised. He had me put her on revolution even though she’s an inside cat. Within a few hours some of her hair where he applied it was GONE and the patch of hairlessness became two patches and grew in emptiness over 24 hours. Sorry but these pharma jerks that create these things could really give a you know what about the pets. I workin biotech in a company that makes test strips for diseases and I see the shoddy work that can happen. I will not give my cat this poison.

If Revolution was not responsible for seizures in my border collie, (see above post) please explain why the dog has not had repetitive seizures since we have changed treatment. It is indeed Revolution that caused seizures in this particular animal. No further seizures have been noted since the product has been discontinued, no other changes were made in diet or other meds given prior or after Revolution. Revolution is to some animals as Penicillin is to some people. This is not anecdotal, it is fact. There is no other variable that could have created this issue that is known to us. While our other Collie appears to tolerate Revolution we have reduced the dosage to about 1/2 application. Who knows what other unseen damage may be occurring at the organ level. As I previously posted as soon as this product is gone we are changing our product to the aforementioned products.
Chances are probably 1 in 10 maybe a bit more your cat or dog will experience issues with this product, when you consider the amount of cats and dogs using this product that's a hell of a lot of sick animals. By the way how much were you paid to post that? Or are you Zoetis? And no I'm not here plugging Seresto or Iverheart but I'll be damned if I'm going to knowingly apply a product that causes harm to one of our dogs.

Both my cat and my dog had a reaction to Revolution. My dog recovered after three days of vomiting, diarrhea, lethargy and stiffness in his hind end. My cat has suffered severe consequences. She had a week of not eating so I was able to give her subcutaneous fluids and force feeding. She didn’t want to move, she was very lethargic and strange stiffness again in her hind end. She finally recovered but then lost the function of her left hind leg completely. She will live but is now disabled. I have had many animals over the years including fostering many rescues and used many flea treatments but never had this reaction until using this product. Reading the studies on Revolution side effects it does talk about some animals having adverse effects. Selamectin is the active ingredient and is a neurotoxin which attacks the central nervous system, it is not meant to cross the brain blood barrier in mammals but does in fleas, etc. Unfortunately it looks like it will in some mammals, namely our pets, and causes the same poisoning as it does to fleas! There is no antidote but supportive care will give our pets the best chance to recover. Obviously I will not be using this poison again on my animals, I do understand that many pets are okay but after seeing the suffering it caused mine I won’t risk it on the others.

REVOLUTION plus almost killed my cat!!! Do not use this horrible deadly medicine the company who makes it Zoetis won’t take responsibility at all!! Said reaction must occur within 24 hours - not true!!! My 3 year old healthy perfect cat got revolution plus at her vet appt and 5 days later she started have a grand Mal seizure that night!!!! Her entire body was convulsing she was foaming horribly at the mouth like a volcano of foam coming from her mouth and then her body started thrashing violently everywhere -her head banging against the floor over and over- I was screaming and crying thinking my cat was dying. I rushed her to the emergency vet since it was 11pm. They sent us home and said if she had more seizures in the next few hours she would have to be admitted to hospital. She had two more seizures about an hour after we saw the vet. She has been on anti seizure meds and anti biotics since due to this horrible Revolution drug. No one warned me of these horrible side effects!!!! My cat will never be the same. She has suffered torment and I am traumatized from this all.

I have 3 cats, ages 2 1/2 yrs. 4 1/2 yr, and 5 1/2 Yr .The youngest and oldest both have medical problems with severe constipation, resulting in the young one having surgery for spinal stenosis. The oldest has inflammatory bowel disease. so has a compromised immune system. For the first time I gave all three Revolution Plus II even though they are strickly indoor cats. The oldest one is very lethargic and just lays there, has vomited, and had a small amount of bloody diarrhea. He has been 3 days since he has eaten, even his favorite treats. I know after a short time they can get fatty liver after a short time without food. It has to be the Revolution. The youngest is showing milder symptoms so THE WILL NEVER, EVER receive that medication again. Even 2% chance of side effects is too much.

Our 18 year old cat couldn't stand up one morning and the vet diagnosed a blood clot in her legs and wanted to put her to sleep. Luckily, we took her home instead. She started getting better and didn't have a blood clot, but a few days later she had a seizure. I had switched her to Revolution Plus two months earlier and I believe that is what caused the seizure and trouble standing. She still has some trouble with her back legs, but is much better after not using Revolution Plus any longer. Despite two FDA reports to the contrary, the vet office claims that Revolution Plus is safe!

My two dogs had mites, I had tried all the holistic remedies. The Vet prescribed Revolution. The next day the 15 yo 8 lb Yorkie was having diarrhea and the 7 lb 5 yo one was vomiting. I called the manufacturer. They said that was very unusual but should not last very long. It now has been 5 days, the diarrhea is minimal and is intermittent loose stool, The vomiting is only at night and is yellow foam. He has a good appetite. The Vet said just watch him. He doesn't need to see him as long as he is eating and drinking. This doesn't make sense to me. Did not happen before the Revolution. Side Effects from it. I won't be using it again.

I applied Revolution to my adult dogs. My one Bichon didn’t look well and started to tremble of sickness. Vomiting several times yellow bile at first. Then it progressed to vomiting blood. Drinking a lot of water then vomiting blood and water. Scary. We had stepped away for a few minutes and came back to a smelly bloody splash of blood on the floor that we think came from her bum. So scary and she was in dire condition. Decided to give Metronidazole as it reduces inflammation and controls diarrhea. It works quickly and within a few hours the blood had stopped but still vomiting the water. Gave second dose and by morning she was a new dog. Thank goodness. Will continue for 7 days. Thank god I had Metronidazole on hand.
She will never get Revolution again. Two vets didn’t think it was revolution and said it had be something else. I know it was revolution. Apparently they r in denial.

I have a 41/2 year old poodle. He has been on Revolution for 4 yrs. I have noticed him change dramatically. He throws up yellow foamy liquid, he lay's around all day until the end of the day. He doesn't want to drink or eat until around 7:00p.m. His stool looks like it is encased in dried blood more and more. Cody has been a hyper dog. I've had poodles before but they were never that hyper. Also he can't take the heat or cold. I thought it was just him. Now all he wants to do is sleep and that is not like him. I have been saving money to take him to the vet because this is going on day after day. It started off slow but its getting worst. Since Cody was a year old he's had a sensitive stomach. He on Hill's I/D. and I thought his spitting up was because of that. As I read all the different comments I'm beginning to wonder if its the revolution. All of the things I mentioned was in the insert of the box of revolution. I going to stop the Revolution to see if he improves. I'm still taking him to the vet to make sure he isn't bleeding internally. Has anyone had their dog or cat with these symptoms?

I had cats when I was young and they lived a long time and were healthy. In recent years I have had three. Two died young. One was only six when she began to hide and then developed unexplained seizures. The second was practically a kitten when she first had a severe vomiting problem, recovered, and then later wasted away rapidly (and seemed to have abdominal pain). The guess was lymphoma but we didn't have money to do an autopsy. She was very healthy until she suddenly became ill. She had been an indoor cat until we got her. The third cat is still alive but is only two years old. These three cats were on Revolution monthly. The third, the only one still living, is on the Plus. Her fur falls out where it's applied. I'm starting to think that it's not my fault that I can't keep a cat alive anymore and that it's the Revolution that's the problem.

Yes I have even had them in female cats after giving revolution. EVERYONE, just use Capstar. If you use it enough and the right way, you won't have fleas. Start with twice a week, then once a week for a month. IN the summer give it about every two weeks and in the winter about once a month. It will break the flea life cycle and no more eggs will be laid to hatch later. It is much more safe than any of those topical poisons. IT will make your pet itch as the fleas crawl and die, but it is NOT a reaction to the meds, but a reaction to fleas dying. The vets want to sell you the expensive stuff. It is a big money maker for them. Also makes them more money when people bring their sick pets caused by topical flea meds, in order to treat them.

Yes. It's our first time using Revolutuon Plus and two of my cats after their second dose (30 days they had dose 2) have a urinary tract infection (UTI). I have never had a cat with a UTI.
One cat is on antibiotics now after a ton of tests that diagnosed him with a UTI. We say him yowling in the litter box. I pray he will be ok because my other cat died a week ago.
My cat sadly had to be put down and it broke my heart. He was diagnosed with diabetes a few weeks ago and we already had him on RP before we knew. He then stopped eating or drinking, was vomiting. We took him to the pet hospital and they diagnosed uti (2 weeks after second dose of revolution plus). I dont know it it related but TWO cats with UTIs? Vet said UTIs are not contagious. My cat got worse and on the 3rd day of hospitalization he had a stroke and we put him down. I'm scared about the revolution plus. The vet didnt think it was the medicine because it sisnt happen right after the dose but I dont know.
I'm scared because I have other cats on the medication right now also.
In addition to the loss of my cat, fear and worry the vet bills were thousands.

I took my 5 1/2 y.o cat to the vet last week, Wednesday 9/9/20, checked out as a healthy cat no fleas. Vet recommended Revolution and had me buy a six month supply, he said I would save money. Saturday I noticed my cat was pulling out large amounts of hair, scratching / itching and he began to develop a bald spot where the medication was applied. Tonight the spot is larger. My only regret is not researching this before the vet administed this poison. ☹. Will be calling the vet in the morning.

Our poor cat is enduring some real Frankenstein-type stuff at this moment, scared and frustrated I searched the subject of "Revolution chemical burn cats" and this is the only thing that shows up, besides a Reddit post, that IS LAYING IT ALL OUT THERE about the TRUTH in regard to this treatment that I will now only refer to as "the poison".
We have three cats that have been given this, seasonally, for years.
This year, January 2020, I began my routine of applying to all three but only had two doses in my pack, so I split between them. We have one cat, Teeny, that is like a dog in that she wants to go out and hang all day. She's the reason everyone gets dosed, and is now the reason they will never be again!
We're on the coast, in South Georgia, so I wasn't sure when I began to see Teenys hair in little tufts, what was going on. She gets into scrapes w all types of wildlife and goes to vet, gets treated w antibiotics or stitches, stays inside, subjects us to her teenage temperament, heals and goes at it again. This year, however, everything was different. She started to walk a little wobbly and that spot on her back just kept looking worse. She started staying really close to the house when outside, I feel now it was lethargy, and began vomiting frequently yet not with any regularity. That spot was turning really dark pink under and the tufts were looking more like clumps. Her coat is white, so we really could monitor the progression of the situation easily. I told my husband that I suspected this was possibly an irritation from the poison aka Revolution.
One day she came running in and had an inch long gash on her back very close to the spot. I immediately thought, "she was rubbing up against something, scratching her back and the whatever was sharp enough that it cut her". This was January. My vet stitched her up and she donned her dredded soft surgical collar. *please note, I put this on her the opposite direction of a hard collar, like a cape, not a halo.
It was healing well, when she, through her soft collar, scratched the stitches out of her back! I was distraught and she was a mess. Back to vet to now get staples! This poor cat was so irritated (the spot was underneath the soft collar, mind you) that she couldn't readily scratch for relief, yet she somehow managed to dig (or chew) out 2 of the staples! The vet replaced them and she was now in a hard (halo) collar, PLUS the soft one to protect the wound, and receiving Prednisone for the itching and antibiotic shots for infection! FINALLY after 5 weeks, she was healed....until she comes in for treats one day and I'll be damned if she finally, now, scratched a huge HOLE into her back precisely where the 'spot' was located!
It has been now, 6 MONTHS that my poor girl has been STRICTLY INDOORS and WEARING A FKNG COLLAR because every time this heals, she completely rips it open scratching herself. I am SICK that I actually caused this, I did this to our baby!
I called my vet in tears last week because she was nearly healed completely, AGAIN...and has opened the small scab back up. It's continually a raw, bleeding wound that exposes her muscle between her shoulder blades. I asked our vet how long would she force an animal of hers to endure this? She said, "okay lets do another round of Prednisone and oral antibiotics and see how it looks, in a couple of weeks and If she's still going at it, I will excise the entire spot and stitch it all up and hopefully that will be the fix". Like, seriously???
I am so beyond frustrated and upset and literally would like to know IF ANYONE has endured any of this behavior from their babies? Also, WHAT WOULD YOU PERSONALLY DO at this point? Excise and stitch?? I mean, I'm certain Teenys hair will never grow back there, the skin is so thin and when it does heal there are visible small veins just under the surface of thin, stressed, skin just begging to heal. It's so pitiful.
FK you, Zoetis & Pfizer!!!

The vet suggested Revolution as a precaution for my senior cat. I gave it to him 2 weeks ago and he has not been the same since. Very stiff, staggers when he walks, lethargic, loss of appetite. I don’t think he will recover—it’s been 2 weeks. He is miserable. I am so sad.

I genuinely don't know what to do. My cats have been on revolution for 3 years now. We don't treat them year-round, but during the warmer months. My cat just had a seizure this night. He first urinated a little, started meowing very loud as if he was shouting, ran off to a corner, started scratching at the carpet, and then he began to have a very violent seizure with tremoring, head shaking, jaw moving, foaming at the mouth, and unconsciousness. It lasted for about two minutes, and afterwards he was very calm, seeking attention, and purring. I am glad to know that he wasn't hurt from the seizure, but it was a terrible sight to witness. Looking back, it is very possible that he could've had a seizure prior. There was another instance where he urinated, meowed loudly and ran off. Then, he came back and had a lot of saliva/foam at the mouth. I didn't see what happened, but comparing it to tonight, he very well could've hat a seizure. I have another cat who threw up tonight a few minutes later. She throws up every once in a while.

I am wondering if there is any link to this odd behavior and the Revolution. I haven't notice anything weird until these past few months. I am going to take my cat to the vet soon and see if there is anything wrong with him. If he comes back as healthy, then I think I will stop giving my cats the Revolution for a while and see if any symptoms come up again.

Does anyone know of any other flea/worm preventatives that are much safer? Or is it fine to forgo any preventative treatments altogether? My father never gave his cats anything or took them to the vet growing up, and they all lived to be old, so I am wondering if cats are better off without the risk of modern medicine? I hate to think like this because I'd like to think that innovation is for the better, but I hate to see my cats be put in possible danger from rare side-effects.

I've been giving Revolution to my 2 cats during flea season for the past few years. Recently I noticed that the cats seem to get really itchy in the week before their next dose is due. I assumed it was fleas starting to make their comeback as the Revolution lost strength. About a month ago I rescued a cat and brought him into our household. He hasn't been treated for fleas and shows no signs of scratching or chewing. I came on here to see if anyone else had noticed itchiness just before the next dose is due. After reading what everyone else has had to say there isn't a chance that I'll put that stuff anywhere near my cats again. Perhaps my two older ones will gain back some energy and enthusiasm once they've been off it for a few months.

I applied Revolution at the right dose to my 10 month old Maine Coon. He started staggering and walking funny.
$1000 of tests have thrown no light. Although he comes from a reputable breeder that tests for genetic issues we are still waiting for a genetic lab’s results on more tests. He seems a bit better and has started jumping on bed but still he does not move normally. I have used Revolution before with no problems but this time I have to blame it. Will follow up with end results.

Revolution Plus killed my cat. Gave it to for the last 6 months. Did not make the connection when she would throw. Gave it to her as usual. She threw up that evening, and the next day all of a sudden her legs would not work. Brought her to the ER, and had to have her put down. Do not use this product on your cat!

Bad reaction to Revolution Plus after 1st dose topically on 5 year old Chihuahua mix.1st day shook his head and scratched his neck.2nd day about 48hr started trembling constantly, hiding, anxious, seemed weak walking and wouldn’t jump or cling steps. Ate if encouraged. Total behavior change. Worst at about 60-72 hrs. 2 visits to emergency vets, vitals normal, no fever no obvious injury. Normal labs. As owner I check the box of heart worm Med and realized the changed Med Revolution was new and the best explanation. We have a case# with the manufacturer though the vet. Day five the symptoms are less frequent and less severe with some times of being norma, but I wish her back to his playful self, We are hoping and praying for a full recovery. I will try to post again with an update.

The vet pushed me to put this on my 4 month old pomeranian puppy and since then (2 weeks and half ago) he has been lethargic, heavy breathing, vomit once, small appetite, and less potty (poo). The vet never told me there would be side effects and this could be life threatening for my little guy ESPICIALLY when he's coughing and he might have kennel cough. Does anyone know if this could kill him after 2 weeks of it given or is it passed? Im pretty worried and when I contact my vet they don't get back to me......

I applied revolution on my cat on 2 separate occassions both times he had a violent seizure. I didn't realize the cause until the second seizure because there was a 1 month lapse of not getting medicine with no seizure that month. Took my pet to vet and told them what happened but they denied my theory that the Revolution gave this adverse reaction. I'm presently watching over him. He is not quite himself. Praying this pass. I will never use medicine again. Is there anyway we can hold the manufacturer & vets for pushing this poison for profit? Is their any way to get this out my cat system? Please HELP!

My 5 year old cat had his first seizure back in January about 3 weeks after his revolution treatments. He’s been on Revolution for about 5 years now. After the January seizure we took him to the ER and his regular vet. All bloodwork came back normal. Skipped a month of Revolution and no seizures. Gave him on the Revolution again a little over 2 weeks ago and he just had a another seizure. The vets didn’t think there was a connection. I’m thinking it’s from the Revolution. I’m stopping it immediately. He’s an indoor cat that sits in the screened in porch but he will now have to stay inside. I’d rather take the chance of fleas than see him having seizures. They must have changed something in the formula. This stuff is poison!

We used Revolution on one of our cats who just saw the vet that week of a good health checkup, he saw the doctor on a Wednesday and he also got all of his update on his vaccines, so we waited until Sunday morning to give him this flea medication, by the evening of Sunday he suffered from something and died in my arms. We believe it was the flea medication but we have no proof but will never use this med any more

Revolution has been proved to be safe for dogs and cats that are already receiving vaccines, anthelmintics, antiparasitics, steroids, collars, shampoos and antibiotics. Still every medicinces don't suits to every animals need to take a vet recommondation as they understand all about your pet better.

Clay in a pets food is a good idea. "Sacred Clay" is one of the better brands cause it so fine. Clay will absorb, heavy metals, chemicals or radiation and animals normally eat dirt with their catch. Yet house hold pets are starved their minerals from soil. Grass is essential to supply to and Diatomicious Earth is the best flea treatment and way cheaper!

I used this on my cat and two days later noticed he was having trouble standing up and within the next 24 hours he was completely paralyzed except for his head. The ver I got the meds from of course said that it could not be caused by the meds and sent me to an emergency clinic that charged me a fortune and told me they did not know what was going on with my cat but that it definitely wasn’t caused by the flea meds. They put my cat on a lot of other medication that did not help at all. Finally I went to a third vet that was willing to say that it was a classic case of toxicity caused by the Revolution. He told me to stop giving my cat all the other meds the emergency clinic put him in and just let the flea medicine work it’s way out of his system. I did that and within a few days my cat started walking again and has made a full recovery. But he was completely paralyzed from the neck down for over a week. If your cat experiences something similar, just keep giving them wet food and water (I used a syringe for water) and give it time to work out of the cats system. Please don’t have your cat put to sleep.

Thank you for giving me hope. I'm terrified right now with how my poor pup is behaving. He's so ill and miserable. I took my dog to the vet last night because of the Revolution flea meds I put on his neck - but like you, the vet acted like it's something other than that. They run all the tests, tell you it could be this or that, but it's really toxicity from the flea meds. Stop covering up for big pharma!!!

Never happened before. I was also painting in my garage when it happened and the dog was with me.... My vet without any doubt there was no link between revolution and seizure.

I gave my 19 month old Irish Terrier Revolution three days ago and he's listless, has no appetite, vomited, running a temperature, stiff joints. I called Revolution (phone number on box) and the rep said that some of his side effects can happen. I do not think that any medication that could potentially kill or cause health issues should be given to our animals. Shame on big pharma and shame on the medical profession for acting like this isn't a big deal. My dog was happy and joyful the day I put that toxic medicine on his neck. He's been miserable for three solid days. The vet has nothing for him and will not link it to Revolution. Lab work showed elevated white cells (his body trying to fight off toxins) and his abdominal x-rays were normal. Shame on all of these people.

I had used Revolution since my 9 year old cats were kittens. 5 year hiatus in which I used generic brands from BJs, etc.. No problems. This year I used Advantage Gold and they both had diarrhea for close to a month. Went back to the Revolution and one of them is having severe reactions. Total behavior changes, massive weight loss, listless, etc. Seems to have issues walking (sort of runs to the one space he is occupying as if there is something hot on the floor). Will eat when I encourage it, which I've done consistently. Same with water. I have to initiate that. It's been 3 weeks now and I'm hoping that the poison will leave his system and he will recover. I will NEVER use this product again. Perhaps they changed the formula? Made it stronger? I was always a bit curious about the idea of having poison in their bloodstream for a month at a time. Now it seems obvious that it is a bad idea. It may be because he is 9 years old now, but if age is an issue, it should be clearly stated.

I have 3 cats and this medicine was recommended by my vet. After consulting him about taking my kids for a stroll in the park he said it's best to give them Revolution just to be on the safe side. Heartworms is the biggest danger obviously and this medicine is meant to prevent it. But at what cost? I've read bunch of scientific reports about the researches that have been done and lots of other stuff until I found this article. No way I'm giving them it now. But I do have a question though, should I be at all worried about mosquito bites and heartworm disease if I only wanna occasionally take them to parks and whatnot. Plus they're feline and I've heard heartworms are a whole lot more common in dogs. Besides, we're not planning on going out at dawn, dusk or night, only during daytime though I do know mosquitos are active even during the daytime. I do wanna protect them from heartworms but I definitely don't wanna be putting their health at risk by doing so. If it helps, I'm in Ottawa, Canada. Any advice will be appreciated. Thank you.

I’ve been in tears all day. My beautiful 15 year old cat, Apollo, passed away Monday night. I gave him Revolution plus on Sunday night. He was healthy, active, playful and eating perfectly before I gave him the dose of flea control. I’ve given this flea control to all my cats this year & this is the first time I’ve experienced any reactions. I’m devastated. Didn’t even have the opportunity to help him by getting him to a vet, it happened so quickly after his seizure. I’m still stunned. I’ve been looking online for answers and found this group. I’m truly amazed at all the stories I’ve read & the sadness and heartbreak this drug has caused to so many people and their beloved pets. I feel your pain, I’m sad with you & hope that many of your pets may recover to good health and that the ones who have lost their babies - May your hearts heal soon. I’m so broken and so angry that my baby lost his life in such a tragic way.

I've been using revoltution on my cat for about a year. put revolution on my cat last night and he started immediately having an adverse reaction. he was disoriented, vision impaired, and scared. I got a moist rag and wiped off as much as I could. he was agitated all night. could not get comfortable. this morning I touched him and he hissed at me twice. He never does that. I have a vet appointment soon. They give you a toxin to put on the cat and then you can't get in to see the Dr again when things go wrong. It's frightening. My cat is doing better today. but i am concerned about long term issues.

We applied Revolution to our 4 year old cat 3 nights ago. A few hours later we were awaken by blood curling sounds from our cat. She was swatting at the air, ramming her head into the walls, then started having a seizure. We rushed her to the Vet ER. They sedated her to bathe her to remove the medication. She was vomiting and acting very aggressive. We're now on Day 3 and she is still on IV fluids and can't keep down food. I feel horrible that my pet sick and I can't be there to comfort her. Is my cat gonna die?? They need to discontinue this product if it's hurting pets!!

100% healthy, playful 2yr old female cat. Mobile Vac Dr prescribed Reveloution Plus for weight 11.1-22 lbs to avoid heartworm. Tech weighed my cat and carrier with blanket and Dr told her to estimate the carriers weight and deduct from the total weight. Documentation says my cat weighed in at 11.12 lbs. Administered 1 dose on back of the neck. 2 hr later cat appeared to be in shock, staring into space, not moving. Then lathergic, not eating or drinking. After 48hr began forcing water with honey mixture with dropper several times per day. Began responding positively but very little progress. Ate wet catfood but just a few nibbles. After two more days no progress. Still lathergic, would cry if I picked her up, nibble a bit and sleep. Day 5 worry she wouldnt make it. Appeared to be dying. Call a local vet saw her within an hour. Explained what happened. He said my cat was most likely one of those 5% that has a negitive reaction and not to ever give her again. Said my cat had a fever and if he can get the fever down she should begin eating better. So they injected her with saline solution I believe in the upper back under the skin to rapidly hydrate her and two antibiotic shots. Said take her home and see how she does. Within an hour she was dramitically improved, eating much better alert etc. Next day doing pretty good, but still not 100%, but eating pretty good. Reacted positive to picking her up, but still sleeping more than usual. Dr called me today asked me how she was doing. Said let him know in a couple of days. So looks like she will make it, time will tell if 100% recovery. Lastly on the weight issue, the prescribing doctor I belive should have prescribed the smaller dose as her weight was virtually on the absolute borderline better to error on side of caution, if you will. Also, for those of you out there, check the prescribed dose and weight for accuracy. I belive the dose was too big for her. My vet said there no way to be sure, but told me to never give it too her again. One more thing, he told me never give my cat tylonol or asprin for fever as that could easily kill her.

I have had 3 cats get a horrible disease called cytauxzoonosis Or Bobcat fever. PLEase look it up. If left untreated, it is fatal in 97% of cats who contract it. IF You catch it soon, enough you have a 60% chance that your cat will recover with hospitalization.
Revolution plus is the only flea and tick medicine that can help you fight the Lone Star tick that carries Bobcat fever. My 1st two that got it were totally indoor cats and I feel I must have had a tick on me that dropped off but this disease has killed cats for every single person I know. so whether or not you think that using these drugs on your cat is horrible and you're going to do it naturally, if you live in Texas, Arkansas, Oklahoma, Illinois, or Missouri, You may come up against Bobcat fever and it kills in 3 to 5 days after symptoms start. Hemolytic anemia causes organ failure & your cats cook from inside with fever over 106°

And the treatment & drugs are extremely expensive ranging $1200-2000 with a long hospital stay. I've used Revolution on my cats for over a year with no side effects other than the cats being really peeved at my for applying it.

Hello everyone! Per vet's advice, I applied Revolution to my 14-week old kitten and 3 year old cat. I didn't touch the product while applying, but I apparently got some on me the next day after handling the kitten. The cats are all just fine (slight loss of appetite), but I am not. The next day I awoke with itching palms, progressing to pin pricks over my body, and two days later, I have hives. Taking allergy med Allegra seems to calm it down, and I assume it will eventually go away. Have used Frontline before with no issues, so first time with Revolution. Anybody experienced this, and if so, what can I expect?

I have an overweight cat who we are actively trying to help lose weight. We know it's a slow process. No more than 6 oz a week to prevent fatty liver.

She gets labs checked once a year to check for diabetes, kidney function, thyroid. She had been coughing alot but then would go right back to playing. Shes dropped some weight. Coughing became less and less

We've always used revolution plus with her but lately I've noticed every time we put it on her, she coughs and coughs like crazy again. Is this a sign of heart disease? It sounds like a wet cough. I've had our vet check her out, had a cxr, didn't see anything concerning. I wonder if she had congestive heart failure. Her breathing even sounds wet after the coughing episodes...then she just runs off and plays...its crazy. Her worm test was negative as well.

Thanks,

Revolution Plus made my 9.5 yr old male cat very lethargic and lost his appetite after I gave him this product for days afterwards. Didnt want to be picked up. Didnt want to move. Never again. He was like this for a few days, took him to the Vet and he didnt think it was the Revolution Plus. I told him i was putting in an adverse reaction report with the Zoetis manufacturer, as he has never had a reaction to using this product before. This was the 4th time i had used the product on him , there were 6 pipettes in the box. Not using this product or other flea meds ever again. Its been a week and half since his flea meds. He is still not eating much, but is eating. I am very worried this dose plus the previous three doses has built up toxicity in his system. The manufacturer rang me up the next day and whilst they sounded concerned, didnt really help other than try to give me the normal Revolution product. As if i would put more poison on him in the future. Never again. From now on i am using Diatomaceous earth around and under his bed( not on him ).
I hope he picks up with his eating. The Vet gave me Mirtazapine tablet to give him if his appetite wanes.
Plus I put a Shunjite crystal stone in his water bowl to purify his water.
I hope he pulls through. He is my world. The next few weeks will be critical I think to his long term survival. No more flea meds for him ever again.
Do not use Revolution Plus for your cat.

3 days post application of Revolution spot on my cat I noticed A bald spot where it was applied , plus it had a red raised crust formed over top and was ozzing a serious drainage like an infected burn. Immediately took her to vets where she agreed it was caused from topically applied revolution and administered an injection of prednisone and an injection of an antibiotic. Since then I have read everything I could on consumer reports from folks all over the country...it's scary stuff these drugs for fleas. I'm looking into homeopathic approaches....am hoping to find something in that arena. My heart aches for all the pet owners who have lost their pets to these awful meds.

I’m feeding and trying to take care of some abandoned and feral cats in my neighborhood and although he’ll let me pet him(the cat with the abscess), he definitely won’t let me try to catch him to take them to the vet. This cat has an abscess on his ear. I give him Revolution monthly,, and he’s due for his next dose in a couple of days, so Is that true that it may help with the infection?

Has anybody noticed after applying revolution to their dog that over time as? It built up, they just seemed to get more and more aggressive, to the point that now they bite and are sensitive on their shoulders.?? I am trying to figure out if the revolution has played a part in his progressive aggression which this breeder said none of his dogs have shown signs of aggression ever... I'm at a loss.
