Les effets secondaires du traitement des puces Avantage

Crédit d'image
Il est vrai, honnêtement, Jon Snow, vous ne pouvez pas arrêter vos animaux de compagnie bien-aimé de puces et de poux tout simplement en les enveloppant dans du coton ... manteaux qui est. Oh brave, beau, idiot Jon Snow.

Heureusement pour Jon et le reste d'entre nous, le traitement de pointe [[[Avantage]] est facilement disponible. Il peut être utilisé chez les chiens, âgés de 7 semaines ou plus, et les chats de 8 semaines ou plus, ainsi que des lapins et des furets. Il est également sécuritaire pour les animaux enceintes et allaitantes. Assurez-vous de parler à votre vétérinaire si votre animal de compagnie est en médicaments, si d'autres pesticides sont déjà utilisés, ou si votre animal de compagnie est sous-pondéré, âgé ou débilité.

Avantage fonctionne comme un paralytique pour tuer rapidement les puces adultes et les larves (pas les oeufs) et donc casse le cycle de vie des ennemis les plus haïs de nos animaux de compagnie.

Une fois appliqué, le système nerveux des puces et des poux est attaqué. Ils sont paralysés et ne meurent que quelques minutes pour entrer en contact avec Advantage - ils n'ont même pas à mordre votre animal de compagnie pour être affecté. Les puces cesseront de mordre dans les cinq minutes suivant la demande et seront morts dans les 20 minutes de contact. Advantage tue 98 à 100% des puces existantes dans les 12 heures suivant l'application et détruit 99% des larves de puces dans les environs de l'animal.

Avantage est facile à utiliser et reste efficace pendant un mois. Il est même imperméable à l'eau donc fonctionnera toujours après le bain, la natation, la flaque étendue ou le roulement de boue (vous savez qui vous êtes!) Ou pour les amoureux de temps humide, la tempête chassant des animaux de compagnie.

Il est appliqué à travers le manteau à la peau du chien ou du chat et se propage à travers la couche huileuse de la peau. Il existe une gamme de dosages disponibles qui dépendent du poids de votre animal de compagnie. Assurez-vous d'acheter la dose correcte pour votre animal de compagnie et que toutes les directions sont suivies avec précision. Peser votre animal de compagnie ou demander à votre vétérinaire de les peser - ne pas simplement deviner et appliquer la dose que vous pensez est correct.

L'avantage est un traitement externe et ne doit pas entrer dans les yeux ou la bouche de l'animal. Pour les petits et moyens chiens, il est placé hors de lécher sur le dos entre les omoplates et pour un chat à la base du crâne. Pour les gros chiens de plus de 25 kg, la dose est répartie entre les omoplates, à l'arrière entre les hanches et à un autre point au milieu.

Comme pour tout traitement médical, il peut y avoir une petite portion d'animaux ayant des sensibilités individuelles. Surveillez toujours votre animal immédiatement après l'application et pendant quelques jours après. S'il ya des signes d'une réaction indésirable ou si la santé de votre animal se détériore, consulter un vétérinaire immédiatement.

Perte de cheveux et irritations cutanées
Une légère irritation de la peau est fréquente sur le site d'application, surtout si c'est le premier traitement de votre animal. Le raffermissement ou l'aspect humide des cheveux, des démangeaisons, une rougeur ou une peau rosâtre peuvent se produire mais ce sont des effets secondaires temporaires. Occasionnellement la perte de cheveux se produit également. Il s'agit généralement d'un one-off et les cheveux vont repousser en 1-2 semaines. Si la perte de cheveux se propage ou ne se développe pas alors consulter votre vétérinaire.

Les animaux avec la peau sensible peuvent développer des plaies qui peuvent saigner si rayé, fendu ou ouvert et puis devenir infectés. Vérifiez le site d'application régulièrement et si ces symptômes se produisent visitez votre vétérinaire.

Odeur médicinale
Une faible incidence des propriétaires ont remarqué que leur animal a une odeur de type médical après le traitement. Ce n'est pas dangereux ou nuisible et ne durera que quelques jours à une semaine après l'application.

Contact avec les yeux
Si votre animal de compagnie parvient à obtenir le traitement dans leurs yeux, rincer les yeux immédiatement avec beaucoup d'eau et consulter votre vétérinaire.

Effets secondaires rares et graves
Les effets secondaires graves sont rares, habituellement seulement survenant chez les animaux ayant des sensibilités individuelles ou des allergies aux ingrédients actifs du produit ou sont le résultat de l' ingestion accidentelle ou une erreur dans l'utilisation des signes produit.Les devrait être perceptible rapidement et en toutes circonstances, immédiate Une attention vétérinaire est nécessaire si vous remarquez l'un des suivants:

Perte de apetite, augmentation de la soif, des vomissements, la diarrhée ou la bave - Rappelez - vous d'appliquer Advantage comme indiqué, hors de la portée de la bouche de votre animal de compagnie. Le produit a un goût amer qui devrait décourager le léchage et l'ingestion. Si suffisamment est ingéré, il peut causer des maux d'estomac et perte d'appétit. Vomissements, diarrhée, excès de salivation, bave et augmentation de la soif indiquent une ingestion excessive ou une réaction indésirable.

Dilatation des pupilles, irritation des yeux ou augmentation de la production de larmes

Difficultés respiratoires, ataxie (problèmes de mouvements), trébuchements, tremblements ou convulsions

Sommeil anormal, léthargie ou non réactivité

Comportement impair, dépression ou hyperactivité

Comme mentionné, les réactions sévères sont considérées comme très rares avec Advantage lorsqu'elles sont appliquées selon les instructions. En cas de précaution supplémentaire, il est préférable d'observer et de séparer les animaux traités pendant 30 à 60 minutes afin de ne pas lécher leur propre site d'application ou celui d'autres animaux. Sinon, Advantage est un traitement extrêmement simple et efficace pour vous assurer que votre animal de compagnie bien-aimé ne devient pas une vie de grande hauteur pour les puces et les poux.

if i feel like my cat is having a reaction, can i wash the area?

Nancy Christie07 juin 2018Reply

Nous avons utilisé Advantage Multi sur notre Chesapeake Bay Retruever, autrement en bonne santé, pour lutter contre les puces. Dans les 12 heures, il était couvert de points chauds et dans les 24 heures, il était aveugle et désorienté. Notre vétérinaire dit de ne jamais utiliser ce produit à nouveau. Et maintenant?? Mon cher chien est maintenant aveugle. Mon conseil est, si vous aimez votre chien ne pas utiliser cet Advantage Multi. C'est du poison à plus de puces. Oh et ai-je mentionné que cela cause des problèmes de reproduction? Voilà pour mon programme d'élevage maintenant. Il était la fin d'une ligne et maintenant c'est fini. Pas de chasse, pas de natation. Nous apprendrons à travailler avec son aveuglement. Cette entreprise doit cesser de fabriquer ce produit.

Hi, I am not using Advantage mullti but just Advantage on my dog, do you think this is ok?

Rebecca Smith13 juin 2018Reply

Je l'ai utilisé sur mon chat siamois 1 an, plus jamais. Il avait une perte de cheveux au site d'application. Les cheveux repoussés, lui ont donné une deuxième application des mois plus tard. Il a eu une réaction sévère, bave, léthargique, tremblements de la mâchoire. Tout s'est passé 4 à 5 jours après l'application de l'Advantage II. On m'a dit que si je l'essayais de nouveau, mon Mac pécieux mourrait.

Charles Edward14 juin 2018Reply

Mon chihuahua a une réaction extrême à l'avantage multi administré il y a 2 jours. Gonflement des yeux, irritation de l'oreille, inclinaison de la tête, diarrhée, léthargie, tremblements, respiration rapide. Ce n'est pas la première fois qu'il a une réaction mais c'est abominablement terrifiant. Je ne donnerai plus aucun de mes chiens, y compris mes deux autres ce poison. Nous sommes prêts à l'emmener chez les vétérinaires d'urgence, appelés et avoir tout arrangé Incase sa respiration devient rapide encore ce soir. Il dort maintenant et nous prions pour qu'il s'use juste demain. Ce produit est 100% toxique. Ne croyez pas ce que quelqu'un vous dit, même les vétérinaires. Mon pauvre petit copain est victime de ce stratagème de marketing toxique. Je ne leur donnerai plus jamais cette merde et je dirai à chaque personne que je connais ce que cela a causé à mon chien.
Ne donnez pas l'avantage multi à n'importe quel animal, période.

What about Advantage, not Advantage multi please? Advantage multi has two ingredients, Advantage only one, Imedacloprid.

Charles14 juin 2018Reply

After our experience we don’t use any of these things on our dogs. Never again.
There are holistic versions made of essential oils we have instead. We will never use these toxic medicines in our dogs ever again. Lesson learned.

Elisabet Sigurdsson14 juin 2018Reply

I applied it to both my dog's just the normal one the terrier is okay but my Bull dog is now having a reaction it's really scary, I won't be using it again

Call your vet but ours said we can give a little bit of Benadryl to stop the allergic reaction. Don’t ever use this poison again it’s not necessary!

Le traitement anti-puces Advantage II Cat est dangereux. J'ai utilisé le produit sur mon chat correctement .... pour le poids correct petit chat, première application à 5 ans, chat d'intérieur, pas de chien à la maison aussi à lécher, appliqué à l'arrière du cou, était un chat sain, séparé des autres 2 les chats jusqu'à sec Cela lui a causé une intoxication au pyriproxyfène ... des convulsions, une paralysie partielle due à des convulsions, une léthargie, un léchage et une perte d'appétit. Les crises n'ont pas pu être maîtrisées. Notez que je l'ai également baignée dans un savon à vaisselle doux lorsque les symptômes sont apparus. Je devais la mettre en sommeil. Le fabricant de Advantage II, Bayer, ne reconnaîtrait pas les problèmes, mais vous trouverez des cas similaires sur le Web. Advantage II n'est pas une option de traitement des puces sûre (et n'a pas fonctionné).

TMorga31 août 2018Reply

I adopted a new kitty. Put advantage II on her, she has a huge bald spot. This was 4 days ago. I will not use it again.

Brenda31 août 2018Reply

Same. Placed it on my cat and next day his fur fell off around medication site. Not using this again!

Pésima experiencia con ese producto , le dio alergia a mi mascota, sacudiendo las orejas todo el tiempo, no puede dormir ni comer , le aplicaron un corticoide y no le ha servido , deben prohibir esa porquería.

Nous avons utilisé l'avantage sur notre Jack Russell il y a 4 jours. Le jour où je l'ai utilisé, elle a commencé à se gratter mais nous avons juste pensé que c'était parce qu'elle avait pris un bain la veille. Elle a maintenant vomi 3 fois ce soir. Ses vomissures sont claires mais il semble y avoir de la mousse ou une substance semblable à du coton au sommet du vomi. C'est un samedi soir, donc notre vétérinaire est fermé et tous les autres aussi. Nous n'habitons pas près d'un vétérinaire qui peut être ouvert. Quelqu'un peut-il me dire ce que nous pourrions faire? En ce moment, elle tremble et frissonne. Merci pour tout conseil que vous pourriez avoir. Au fait, elle a 14 ans et nous lui donnons rarement des traitements contre les puces. Nous travaillions dehors toute la journée lundi et elle voulait être dehors avec nous. Nous avons remarqué qu'elle avait deux puces quand nous sommes entrés dans la maison. Nous avons décidé de l'utiliser et j'aurais aimé que non.

Briana Harden16 sept. 2018Reply

J'ai regardé en ligne pour voir des critiques et / ou des plaintes concernant ce produit. Mon sauvetage BullPei a eu ce 2x et pas plus des deux fois, il a eu des mouches et des kystes énormes comme dans la taille et s'est gratté dans de nombreux endroits. Je me demandais quels autres produits quelqu'un pouvait recommander. Je vous remercie.

My German Shepherd is having a reaction. He's etheric and won't eat and very thirsty. He is my everything! You are selling an unsafe product! I will bring the biggest lawsuit you have ever seen ! My precious boy better be okay..I will never forgive myself for using this! You need to take this off the market now!

Please tell me your dog is ok now after this incident

I used on my cat, "Advantage II", but never again, made the cat crazy, he bit and scratched me. He ran around the house. I called the Vet he told me to wash the cat and watch for foaming of the mouth and seizures. After the washing he seemed to settle down, I do not advise anyone to use this product, it can kill your cat.

[email protected]18 janv. 2019Reply

How long did this last , my cats are acting crazy

mik18 janv. 2019Reply

Advantage II made my cats very sick, Vet had me wash the cats and watch to make sure they didn't foam at the mouth or go into convulsions. I am so ashamed I didn't know better, I almost lost my best friends. Do not use this product, it can kill an animal. They did continue to salivate for a while but did settle down. I feel so sick from this, Ill never use anything like this again for fleas. I cant imagine if it had killed my pets how I would feel. I live alone with my 2 best friends, I would die inside if anything happened to "my boys".

Rozena07 mars 2019Reply

I use Advantage II with my med sized dog and every time we do a treatment she scratches out of control, won’t eat and seems depressed. I’ve been trying to figure out what it was and have now discovered it is the Advantage II topical flea treatment that we just finished (we had the 6 month supply). I feel so bad for her. She doesn’t even have a flea issue when we don’t use it, I just use it to protect her. I’d rather just stop using it and if we notice flea, then treat. This stuff is poison to my dog.

Veronica 24 mars 2019Reply

We put Advantage multi on our Beagle puppy this morning. Now his pupils are dilated, excessive drewling, depressed, won't eat and wobbles when he walks around. I feel terrible I don't know what to do. Our vet is closed. When I called they said benadryl and go ahead and give him a bath. Praying he makes it through the night and is ok in the morning. I'm so scared. Any suggestions?

Shirl15 avril 2019Reply

I used advantage on two of my jack russels. One was 12 and 14. The 12 yr old was my daughters. We noticed a strong smell from the fkea stuff. We tried to wash it off. She started getting really sick and lathargic. She passed withing 7 days of use. She was up and playing then one day took a turn for the worse. We could not figure out what hapoened to her. I used the same batch on my dog a few weeks later. 5 days after use the same thing happen to him. He could not get up. He could not even out his head up. He could not eat . We thought this was the end for him. Its the weekend. No vet. I have been giving him 10 mg bennydryl around the clock. He is now up and walking and eating like nothing happened. Never again will i trust any toxin on my pets. He is highly alergic to fleas. I thought this would help him. We will find another way to deal with the fleas. It only takes 1 flea for him to have a bad reaction. I think 1 flea is better than being posioned. Maybe, this is the new batch they made because fleas are amused to the old batch. Imagine what they had to do to make something that would kill the fleas. Our poor furbabies are guniea pigs.

Dale03 juin 2019Reply

After moving from a state where there are no fleas to California, ( lots of fleas) I used Advantage 2. Within hours my 6 year old cat "Marshmello" showed signs of a severe reaction: watery eyes, nose, and increased salivation. But the worst part was he lost the use of his back legs ! My vet examined him, and after a series of expensive blood tests stated that everyday cats come in with reactions from using advantage 2, and while the drooling and watery eyes would go away the paralysis might be permanent. It's been 3 months now and my cat is still 95% paralyzed in his back legs. Advantage 2 is a dangerous neurotoxin. DO NOT use this product !

Patty03 juin 2019Reply

So sorry to hear about your cat. My cat is having a bad reacion also and I am fearful.

Dalr03 juin 2019Reply

Patty, I'm so sorry to hear about your fur baby. As for my Marshmallow, after several months, 3 different veterinarians, numerous laboratory tests, $2,000+ in vet bills, he is doing better. the neurotoxins in advantage II caused him irreparable nerve damage, therefore he has been put on phenobarbital to control his seizures. He now has approximately 30% use of his back legs. To control his fleas, we use Comfortis, which is only available by prescription but works wonderfully. Wishing you all the best with your fur baby.

Hello, I used Advantage II (large cat) on my completely healthy cat 11 year old cat and within the next few days he started showing weakness in his hind legs. Still eating, drinking, etc, and doesn't seem to be in pain, but he was no longer able to jump, his back legs completely collapsed on him a few times and he's walking with a strange wobbly gait in only his hind legs. Took him to the vet where he had extensive bloodwork and x-rays. Everything looked normal. its now been about a month of symptoms. It hadn't occurred to me that it could have been the advantage. Does this sound like what happened to marshmello? thanks in advance for any help-- the only this the vet suggested was further testing such as an MRI which would be extremely expensive

Sheryl30 octobre 2019Reply

I have been using Advantage Multi on my 2 cats and dog for over 3 months. I couldn’t figure out what suddenly went wrong with my otherwise health felines. My make lost half his fur and my female was lethargic, seemed depressed and was peeing large amounts of blood. $1500 later and nothing is working, I tried another flea medication in between another antibiotic because the advantage didn’t work anyway and suddenly my cats are back to normal. I never would gave thought this was causing it. My mother’s 2 dogs also became deathly ill and 1 almost passed away after applying the Advantage. Never again !

Shanta Swain30 octobre 2019Reply

Just adopted a little 5 year old poodle 4 days ago from city adoption site. She was spaded, and given all her medicines including advantage plus all within 9 days. Alot of meds for a 6 pound dog. Today she had 2 seizures, and she walks a little funny. The vet said she thinks the seizures maybe just epilepsy. But when I looked at the meds she received I saw the advantage plus. Never to use this stuff again, it is poison to their system!

I used advantage on my 17 month old bengal and I believe it has made him sick. He became very lethargic, high fever, no appetite. I took him to the vet and all of his lab work came back normal. I have read about advantage causing issues in other pets. I know that he didn't ingest any of the formula. I purchased the 4 pack for large cats as he did weight 12.5 pounds. He has lost some of that weight now.

Hello! I just applied the advantage II kitten on one of my kitties and the large cat on two of them. Unfortunately I read these after I applied it but don't feel comfortable with them using it, so I washed off the area with dawn soap within 30 minutes after I applied it, should my cats be okay?

Ashley 27 sept. 2020Reply

Hi, I work at an animal hospital and im noticing a lot of clients here upset about the medicines they have been giving their pets. I just want to point out that while it IS a risk to put any of these products on your pets, it is no more of a risk individually as us buying medicine to treat our own ailments. Do some research before chosing a flea prevention. All dogs are different, just like people. Some may react terribly and some may have no issues arrise. At my hospital, we have VERY FEW patients who cannot take certain preventatives and we quickly find the solution because without these treatments, these babies can become so infested that it leads to Anemia and often organ failure, followed by death. Ticks can cause a multitude of diseases and disorders as well that also lead to death. To be honest, every day we all do things, take things, and eat things that could potentially kill or harm us. So, while it is terribly unfortunate to hear that some of your babies have had such a horrible experience, I do want to point out that our babies do need some of these options for protection. Please follow the rules and guidelines and watch the precautions. Some medications are better or worse than others. I do believe we, as a race of "intelligence", we could do SO much better for our furry kin.

Freddie27 sept. 2020Reply

My dog has been treated with every. other. treatment. on. the. market. I've worked in pet stores for half a decade, I have unlimited access to every product, and I vet him regularly and have used every prescription product, including sulfur baths. This shampoo, knowing the ludicrous number of complaints, is a last resort.

But I've got 3 acres in the country, and I woke up, walked to the kitchen, and my feet were covered in blood from all the ticks he brought in the house the night before, WITH treatment. He has gotten ehrlichia once, already. I had to try it.

If he has seizures and dies tonight, it will be far more humane than what he has gone through over the past four years with nonstop irritation and organ damage from ineffectual medicines and diseases brought by vermin. I would welcome it as an end to his suffering. But it isn't gonna happen.

Because I also know the public. Especially pet owners. They will crap their own pants and try to shove it in the mouths of anyone who disputes a word of their testimony because ThEy kNoW WhAt'S bEsT fOr ThEiR BaBiEs. They let them eat the polyester filling from a toy and then blame the stomach discomfort on a brand of food the vet recommended.

Every pet owner is a Karen. Ignore the bad reviews.

I put advantage on my healthy 12 year old cat . He developed huge cost like bumps on his neck and he lost fur all around his ears and at the area I applied it to on the back of his neck . I washed him w dawn soap but the damage is done . I feel so horrible for putting that poison on him . Never again . He’s miserable and I feel horrible for doing that to him . I did call a vet and they said 1/2 dose of children’s Benadryl . That seemed to help a little bit . Poor kitty king George . I hope he gets back to normal soon

Alejandra07 Nov 2020Reply

This is the third time using on one of my kittens and I found this site because I had googled side effects. I think she might of gotten some on her paw and licked a little bit of it. Washed the paw out and am now monitoring her. No big side effects after the first two applications and I have another kitten who also didn't get any side effects with both his applications. After reading all these comments I am freaking out. I've never had an issue with the prior two applications and actually saw a lot of good reviews for advantage II for small cats. Really hoping my baby won't have any major side effects.

UPDATE: washed the area out with mild soap and water and made sure to dry it off. Kitty was fine afterwards. My other cat feel asleep belly up and it dried up on it's own. No side effects both applications on other cat. They are both 7 month old kittens and I used Advantage II for small cats. I don't think I will continue using it although I didn't have major side effects as many people stated here. I will probably look into maybe a flea collar or some other type of flea treatment.

Used advantage on my 15 month old cat 4 days ago ever since she wont go near me she is very edgy and not eating properly she walks around with wide eyes like she's scared hopefully this will wear off and she'll be ok, i wish I knew how this would affect her there should be a warning about how dangerous this treatment is for animals.

I switched to advanced 2 and noticed the next day my cat had diarrhea and it was so bad he couldn’t make it to his liter box now I have him shut in my bathroom now for three weeks and still having accidents but not as bad it’s a good thing I’ve noticed or everything would been ruined so never again on advantage 2!!

Matthew Stark 03 Fév 2021Reply

Advantage is nasty... period! I've had to use this product because it's effective but it hurts the hell out of my cats. It burns their skin and the fumes from the alcohol content causes them both to squint. I feel like the meanest person in the world for having to use it on them.
They are indoor cats 24/7 but a neighbour in my apartment building allows her indoor/outdoor cat to wander the halls. He sits outside my door daily. I'm at a crossroad. I've tried all natural means and nothing has worked. The manager of the building doesn't care about this matter.
So, if anyone knows of something else that's harmless except to the fleas please inform me.
Anything from Hartz is an absolute no! I'm surprised that they're still still selling their flea collars. As for Bayer, the makers of Advantage, well that's another whole ball of evil.

It is horrible what my Jaq has been going through, he was the perfect guy. on June 12 he had is 1st dose of the season and has scratched his neck to the point of bleeding. it is now 3 wks later and he has started scratching and bleeding again. Bathing is Not an option. I feel horrible that i allowed my good boy to be tortured like this!
Why is this garbage on the market. DO NOT SUBJECT UR FUR BABY TO THIS!!!!

My previous comment was definitely not directed to this site. It was pointed at Bayer the makers of Advantage.
I'm very thankful for this site, Petbucket for allow me to express my feelings of anger towards this product.
I get frustrated and write from the top of my head. I should self edit, yes.

Hi, I recently put advantage on my 10 1/2 year old cat and he had 5 seizures in the slave of 40 minutes , I took him to the out of hours vets and they gave him an anti allergy injection which helped for 5 days and now today on the 6th day he has had 3 more seizures and idk what to do he’s been to the vets 3 times and is going again tomorrow in just under 14 hours, he is now asleep but since I’ve given him his file treatment he has been drooling from the mouth, he wobbly and then falls on his side and twitches, his breathing is also now heavy. It is so horrible to see and I just want him better, has anyone got any ideas if it isn’t the flea treatment, would be appreciated

What if you have two dogs. They play a mouth each other, they will get the others back so what can be done to make this safe? Multi use pills are out due to seizures.

Used the Advantage II for Ferrets on both my ferrets. Never had any reactions or anything. Just like humans that take any medicine, pets taking medicine comes with a risk. Whether that be flea treatment, pain treatment or anything really.

Just used Advantage Plus on our Carin terrier X and he has extremely bad chemical burns.
Called the company and was given a case # "in case the vet wants to know the active ingredients " He is miserable, we bathed him in Dawn dish soap then gave him 50mg of Benadryl also but Rx burn cream on the spots and had to put a shirt on him to make him stop scratching the burn spots. I am completely shocked at what this has done to him. There is no recourse if I take him to the Vet it's all on me....Ya I am not happy to say the least. Not sure what else to give him to calm him down and stop the itching.

Cat freaking out. I used it on my siamese cat and within hours she started to have iritic behavior! I am on day 2 of trying to detox her with Chlorine Dioxide (MMS). She sleeps a lot and wants to be very very close to me. Hides under and sheet or blanket she can and twitches one of her ears. Other times she stares at a blank wall w/o blinking. Its like she has completely lost it at times. Never EVER again will I put those chemicals on her body -- that is if she makes it out of this :(

I've used Advantage Spot On for years and my cats have been fine until their latest application. It appears to have turned my cats neck blue!
Luckily he seems to be okay in himself but I can't see anything about this online.

Vet gave to our 4 month old English bulldog, applied it late last night and 12 hours later he’s in a coma, thought he was just sleeping til I tried to wake him up to feed and he was just limp, then as I tried waking him he’d begin seizing and go limp right away. Currently at the vet but please please avoid this poison. We are sooo upset. Should have researched it but just assumed the vet prescribed it so figured it was safe for a perfectly healthy pup. This shouldn’t be an option for any animal.

My cat almost died...still in observation at the vet..he has suffered terrible fits of shaking...cannot walk, crying, fits and total misery. Please don't use Advantage if you love your pet, it's poison, expect nerve damage and kidney failure.

This product is horrible
I used this on my 9 year old Jack Russell on Thursday night when I woke up Friday morning he throat was so swollen he has burns on his skin. Hives all over his back and the rest of his skin red raw. I was petrified.
My 8 year old Jack Russell has sores on his skin too and not eaten his dinner since.
I’m so sorry to read all these stories.
I will never ever use it again!

I administered Advantage multi on my two 3 year old pups and senior dog on Friday night.On Saturday one of the pups was not eating and lethargic. He also had diarrhea. On Sunday, he drank some water and vomited. He seemed to be getting better until I came home from work Monday and he had died. I’ll never use it again.

Hi my vet issued advantage flea treatment for my lop eared 18month old rabbit on Tuesday although he didn’t have fleas he had a very small sore at the side of his eye, he’s a house rabbit, within 18hrs my rabbit started to fall over, I took him straight back to the vet and he said it could be E cuniculi which is fatal, and completely dismissed my concern it could be the flea treatment, we are now in day 3 and he is getting worse, I don’t know what to do, please can anyone give me advise

Gave my puppy the correct dosage of advantage flea treatment and 48 hours later he suddenly won't settle to go to bed and has had diarrhoea, he did it in his cage for the first time ever . Wonder if this is a coincidence or a reaction?

Take him to the vet, he is having a bad reaction to the medication

Gave my mastiff Advantage multi and 5 hours later, he could no longer walk. He is at the emergency vet now- they said he was also partially blind Praying 🙏 that they can save him and get this poison out of him.

I have used Advantage Multi on both of my cats for three months now and both cats have developed this horrible odor that they did not have before I started using it. One cat is nine years old, the other is three. Has anyone else noticed a smell with their cat?

One of my cats started drooling really bad about an hour after treatment, but it only lasted a few minutes and she drank water and it cleared up. I have been monitoring her and she seems to be her normal self since. Another adult male lost his hair and has irritation at the site where Advantag II was applied. Should I not give them Advantage any longer, or maybe for a couple of treatments use the kitten dose even though they are adults?

My 12 year old otherwise healthy cat within hours started vomiting, next day lethargic & won’t eat or drink. Day 2 loss of motor function, stumbling & hissing. Unfortunately it is the weekend & ER vets are far away & too expensive honestly. I am thinking & preparing for the worst. I am heartbroken. He was/is my best friend. So sad big pharmaceutical can get away with this. Pure poison. Watching my pet slowly slip away is torture. I realize this product works for many, but I will certainly seek a homeopathic flea treatment for any future pets I may own. If I ever decide to own another pet. Very angry/sad
Grieving.

Does an *unopened* tube of Bayer advantage canine ever $/xpire or lose effectiveness with age

Advantage II: just administered 3rd application following the summer months to my Siamese. A day later he's scratching and grooming obsessively. A few days later I notice massive hair loss all over his body like hot spots, however, no discoloration nor inflammation. The hair loss continues. The scratching continues - as the fleas are still alive and well! He's evidently having a bad reaction. Never again! Heartz flea collar did the same as the fur around his neck vanished (but grew back)... Collidal Silver in his water to help him through this, whenever that might be. In the future - DE in his food to deworm, perhaps Revolution...Glad I found this site! They need to put serious warnings on their packaging.

I just used Advantage for cats on my pet Polly. Within 10 minutes she started acting unusual, dashing around my house. Polly was foaming at the mouth so excessive salivation. I was extremely worried and tried to round here up for an emergency Vet trip, but the symptoms subsided within five to ten minutes. I have used Advantage in the past without incident, but I guess she has become sensitized. I am researching alternatives.

I was wondering if this medication can cause dogs to have moles grow on their body in different places.

Advantage killed my cat! My dog is now sick and am praying for God to heal him in Jesus Name!!
