Readers Respond: Has your pet ever had a bad reaction to a medication or topical treatment?

Responses: 27

By

Has your pet experienced an adverse reaction to a drug or topical product? There were several reports about Promeris in 2008 and flea and tick products in 2009.

The first thing to do is call your vet as soon as possible. It is a good idea to write down any details you can remember - the time and method of administration, what signs were noted, and what time(s) those signs appeared.

Please report your pet's adverse reaction, either via your veterinarian or yourself. It is important to report these events to provide data and alert other veterinarians, regulating agencies and ultimately, to protect other pets.

frontline

In May 2013 I put frontline on our 12 year old Golden retriever and our 11 year old Great Pyrenees within 3 hours our golden girl threw up 7 times,was totally lethargic looked death warm over,our Great Pyr was fine.I called the vets office immediately told them of the frontline and the heart guard,they told me to get her to the office immediately so I carried her to the car and was at the vets office in less than 20 minutes and they had her in the back washed her off and gave her a shot to protect her organs.Doc did tell me if I did not get her in so quickly she would have died,and stated that she had a severe reaction to the frontline.She still has nerve damage in the spine,if she runs to fast her back legs give out on her,summer was physical therapy swimming in the pool,at first she needed a life jacket but she did better as she went along,but this winter we might have to give her injections to help support her muscle.front line denied all responsibility.

Frontline severe adverse reaction - cats

I've applied Frontline Spot on to my two cats, 13 and 2 years old, both healthy. I applied the ampule as described on instruction sheet, as far as I was able to see, neither of the cats was able to lick it. Both behaved lethargic and showed a lack of appetite next day. While younger cat recovered without any visible consequences within 24 hours, the older took a downfall. He stopped eating, wasn’t able to walk straight, and suffered from pain attacks. Veterinarian diagnosed massive liver damage, cat developed ascites as well. Now, 6 weeks pass, he seems to be recovering his appetite and behaves clinically well, but his prognosis is bad, due to liver damage. Fronline LOT# I used: G21252AS; Exp Mar2014. Date of application ~20-June-2013.

Miscarriage x 2

I am a hobby breeder for 40 years and have been a veterinary nurse for 30 years . I believe I am a responsible breeder and a asset to my community of dog lovers. Last month I bred 2 of my spaniels and wanted to have them flea free during that time so I placed ProMeris on them for their size, ONLY after reading the label and calling the company to verify if this was alright for a pregnant dog, which they said it was. My girls where verified pregnant and at day 45 they BOTH started a horrible miscarriage !! I thought I would have to euthanize them and really worried that I had some hormonal abnormality within my breeding dogs...... Needless to say they are now very healthy as always, BUT no puppies ! I have since then bred my other girls and of course NO flea control !! They are pregnant and happy passing the 50th day ! So, in my opinion, which I value......the only thing I did differently with my 2 other Happy, Healthy breeding dogs was to place ProMeris on them. You tell me....

adverse reactions

I took another of my cats to the vet. She is 18. She was given antibiotics (£42). He recommended frontline flea treatment at the cost of £22 and told me it could only be bought through a vets. He also assured me it was safe as it is used on 2 day old kittens. I have 5 cats and treated them all using the minimal amount, as I really do not like pesticides/chemical use on animals. I told the vet this but he reassured me it was safe. My cat Wesley seemed unwell on Friday, walking with a wobbly gait. I put him in his box on his blanket, he curled up but was not interested in eating or drinking. As I don't drive I started making arrangements for a friend to take us to the vets when I went back to the box he was dead!! Initially I thought well he is old and we buried him. We were all upset but I was even more upset next day when a friend told me her cats fur had dropped out after using the Frontline treatment. I googled information on the product.

Promeris reaction

Shiba Inu 6 years old given May 4, 2012. Lethargic, drooling, stagering, high as a kite! This is her second dose. Gave her a dose w same reaction a year ago- Vet said then after I notified then of the bad reaction first time it was impossible to be from Promeris. Decided to try again - same reaction. I feel like I'm killing my dog-watching her suffer.

Promeris caused tremors

Day 1 I saw mild tremors when my 2 yr old ACD (Blue Heeler) went to bed with us. Didn't think much of it (thought she was dreaming or something), but the next day they were much worse. Vet said that Collie breeds and Heelers were sensitive to the active ingredient... Now we have to pay for injections of the antidote every 4-6 hours! Thanks for a wonderful product Promeris!

Severe reaction to frontline for cats

I am currently abroad and my boyfriend gave our cat his frontline which we have used on several occasions. This time he has had a severe reaction to it. He is having respiratory problems amongst other things. My boyfriend washed it off within 2 hours of applying it, when he noticed the change in him. It's been 48 hours, within that time he has been to the vets twice and received steroid and antibiotic treatments. Has anyone else's cat had respiratory problems and recovered. I'm so scared and just hoping he will get better asap. My boyfriend said he has drank water and been to the toilet since but now I'm worried about kidney damage/failure.

Promeris Fried my Dog

I used Promeris once in January and then in February. The second month I used this product it Fried my Labs back. So bad, that after $600 in vet bills and 4 visits so far, she still has severe burns and scabs that will not heal. The vet says it was due to Promeris. I called the manufacturer and they seemed indifferent about the side effects. I advise NO ONE use this product on their family pet. The company denies it is from their product and refuses to accept any financial responsibility. They are a bad company and should be taken off the market. My poor dogs suffers every day because of PROMERIS. BAD BAD Product, Buyer Beware !!!

promeris

My 14 year old dog had a convulsion 24 hours after the first dose of Promeris, which I measured and dosed her by weight. My 4 other dogs had no problems at all. I didn't think it was due to the Promeris until the second time it happened after a second dose a month later, again a convulsion 24 hours after dosing, this time the convulsion was much worse, The vet told me he didn't think it could be the Promeris as I had been so careful about the dose, and that more likely she had a brain tumour. She is fine now, well and happy.I will never give it to her again!!!

Bad reaction to Frontline Plus

My moms dog became very anxious and twitchy after having the flea and tick collar on him for about 3 weeks. His appetite is diminished and he is now constantly thirsty and dehydrated. He is not his normal happy go lucky self. After reading everything about Frontline Plus I took the collar off of him and gave him some Benadryl. I will see how he recovers from this. I will not ever, ever put this on him again.
