Have used this product for over a year and my dog is still affected by fleas. Have taken him to the vet and they also recommended this brand but it doesn't seem to be working.

Caused loss of muscle control in cat

published

My cat was given this at the vet after Frontline had become ineffective. Later that evening she was unable to walk or stand, falling over on one side, with tremors of her whole body. After taking her to an emergency vet and returning home, she was not able to walk or stand without falling over until the following day, and slept for the entire next day. It took her a few days to recover. One of the vets had seen a similar reaction before. I would not recommend this product - a chemical that can produce these sort of neurological side effects is dangerous.

Killed My Sweet Cat

published

As today marks a year since my cat passed away from this drug, I reccomend NOT ever using this. This drug caused my cat to become lethargic for days, then he began to lose movement. It caused permanent nerve damage, eventually resulting in paralysis and death. This was after the 3rd use. He bounced back the first two times. Read reviews and do not use this medication!!!

I gave my Lhasa poodle mix one tab in June. It’s now November and I haven’t seen any fleas! I read an article about waiting to see if fleas appear then to give another tab. Needless to say one dose lasted 5 months.
My dog is always chasing squirrels and jumping in the open waters. She Was completely infested until I gave her this magic dose of amazingness.
I was scared at first after reading reviews and kept one eye open all night to watch her reaction to it. I’m pleased with this

Healthy 16 month old cat died after giving comfortis

published

I have used comfortis for about 3 years now on my GSD and 3 cats. After giving them a dose the usual vomiting would occur but they were always fine.
2 nights ago I gave all the animals a comfortis, I always follow directions and am super careful!! They had the comfortis at 7:30pm and in the army hours of the following morning my healthy, strong fit as a fiddle 18 month old cat was dead. He looked as though he had curled up and gone to sleep but he didn't wake up. This product is so dangerous and NOT worth the risk. Please be cautious and think twice about using this product.

Made both our cats very sick

published

Administered to our two cats, both young and healthy. Both began vomiting a few hours later, which continued intermittently for the next 24 hours. One was lethargic, sick, and refused to eat for over a week afterwards. Would not use again.

Cat had a Very adverse reaction

published

Dont use it

published

Dosed two perfectly healthy 8 year old cats. One is dead, the other sick and vomiting for two days. Our cat died two days after the pill after being
off her food lethargic, then died. The other exactly the same symptoms but got better after 3 days.
I want to see this product withdrawn, or see the CEO eat the prescribed dose. I wish I had seen the terrible reviews before giving it to our pets. Now the kids pet is gone, and the product is still being sold.

My Poor Pup

My 1 yr old Yorkie mix has been vomiting ever since I gave him his pill. He won't eat, so I'm not sure how to settle his stomach. Poor thing...

Never use this product causes paralysis and many other serious side effects

published

My healthy 8 year old cat had a severe reaction to this drug which caused massive vomiting and paralysis for 3 days. We had to seek emergency veterinary attention as we thought our beloved pet was going to die. I am going to take this further and after liasing with other work colleagues who are in the medical profession they had similar stories after administration of this medication to their cats and dogs. A terrible ordeal for myself and other family members to encounter.

Hope my review will save lives.

Our 9lb cat given 1/2 tablet of Comfortis

published

Love It!

published

My ten pound Pomeranian scratches so badly if he gets one flea, I feel sorry for him. I have used Comfortis for years and it lasts more than 30 days. I give him another dose when he starts to scratch or if I see a flea. I make sure he has eaten a full meal before I give him the dose. He won't eat the pill so I cover it in cheese or canned food and down it goes.

I gave my chihuahua comfortis but There are cats around my house and they have fleas, then when she goes around the cats she gets fleas again. Will the comfortis continue to kill these fleas?

My advice is to use Wondercide flea spray. It is natural and it works. To stop the root of the reproduction of fleas use a non-toxic powder that dehydrates the fleas, treat the area front and backyard, inside of the house, if you live in the U.S. Flea busters sprays for you and guarantee it for one year.

My Maine Coon X male cat who turns sixteen this coming Monday has been on Comfortis for the past six months with no ill effects till today. He didn't vomit but has been extremely lethargic and is absolutely not interested in food. Yesterday he was eating like his usual self, very well. I don't think that I should buy this product again. What do others think?

Hi Marg, I have a Birman who will be 17 later this month, but I have never given her Comfortis, and I don't want to because of her age, and I am worried that because it is taken orally that she will have a bad reaction due to her age. Instead, I gave her Frontline a few days ago, without any problem, and it has no smell, but in the past I have given her Advantage (which does smell) and she became lethargic and hid in the wardrobe, distressed, trying to lick it off, twitching her skin, and not happy. So for two years I didn't give her anything. She is mostly indoors anyway, but I have two dogs, one who can tolerate Comfortis and it works so well. The spot treatment didn't work for her and she suffered from flea allergy, but the Comfortis has been great for her. She has been on it for two years but I don't give her a full tablet, only 3/4s. The other dog, a 13 yo poodle had seizures 24 hours after giving him Comfortis, even though he also has been on it for a couple of years. The only thing I did differently was that I gave him the full tablet instead of 3/4s. That was last month. This month I tried him again on Comfortis but on a half dosage and he didn't suffer any ill effects. i hope your cat will be okay. It may be that he will be better off with a lower dosage due to his age and health.

Thankyou very much Corinee. I hadn't thought of a reduced dose and after the reaction to my boys last pill he definitely won't be having any more. I don't care what the vet thinks.....Charlie Brown has always been a 24/7 inside cat and hadn't had fleas before. The only reason he had fleas was my son visited with his dog and even though it wasn't evident that she had fleas she must have. He's since admitted that she does. I will buy some Frontline to keep on hand. I have extreme chemical sensitivities and the smell of the Comfortis made me want to puke.
Thankyou again
Marg

I think my cat may have a bad reaction to comfortis. It seems to give her this horrible cough and makes her lose her appetite. Has anyone seen this reaction before? She has lost a lot of weight.

Nope never and I've used it for while
But my advice is to cease using it
Your cat could be allergic to one of its ingredients
Take him to a vet explain it to them
I doubt it's life threatening its most likely an allergic reaction
