About 4 hrs after giving our dog a dose he became lethargic and the third eye was coming down on his eyes. He could only walk slowly and just stared into space! Luckily after a few hours he has improved but we were extremely worried and had no doubt that this product caused this!

This product works to eradicate fleas and my cat Loves the smell of the product but on a full tummy, he wants water immediately after consuming it and vomits 24 hours after administering the tablet and will do so for 3 days straight and be very ginger and sooky. He suffers from feline paresthesia and during these days it is more pronounced like the Comfortis affects his central nervous system. I won’t administer again. It’s one of the only products on the market that works for him but makes him so ill. I can’t touch him during this phase because his nerves are hypersensitive and he bites unless I am super super gentle.

I read the directions very well, fed my cats gave them the medication for fleas, its smells awful, and one cat could not breath rushed, the other was vomiting worst, stuff not well tolerated in cats at all, thankfully the vet gave my one very sick cat IV meds, the other cat was just vomiting and did not stop for like 4 hours, but the other cat had to stay on anti histamines for over a week, I am lucky he lived :(

Treated 3 dogs, each after a meal. Within 1 hr, all 3 were puking all over the house. Now, I'm worried about other effects, plus seeing $66.00 spewed all over the floor.

My dog has always had a problem with being itchy, however Panoramis was brilliant and controlled this very, very well. Then it had a name change, while bizarrely supposedly bring the same formula, but my dog isn't getting anywhere near the same relief. Really unhappy, this stuff is controlling fleas, but absolutely not controlling the general itching she has had since she was s puppy. Far as I'm concerned they've changed the formula to save money and given us an inferior product. On eBay original Panoramis is selling for $300 plus, proof that people are seeking out the original product.

Don’t know how this gets such bad reviews .

This tablet is awesome . Works so friggin fast and my cat Lionel is flea free so bloody quickly .
When he had fleas he’s constantly wet with all the washing, after his treatment he’s back me dry and can actually sleep.

Don’t foot around with the tablet. Cut into 3 and shove down their throat

We treated our 8 year old mini schnauzer with this product with his evening meal. The next morning he had blood in his stools. The Vet suggested to observe him as he was still active and eating. He had blood in his stools for 2 days then thankfully back to normal. I won’t risk using this again it was very worrying to see that blood.

I was recommended a scaled-down dose of Comfortis by a holistic pet practitioner, for my extremely flea infested and agitated golden retriever pup. it worked in 1 hour and has provided amazing relief to our girl. Side effects include joy, relief, sleep, and comfort as the brand name suggests. While I still hate using poisons on my dog, I couldn't watch her distress any longer, and I think a scaled down dose will give you all the benefits without possible negative side effects. I highly recommend Comfortis (in a scaled down dose).

Our first two male rescue cats refused to eat these pills, even when hidden in food. Tried forcing it and I'm sure it resulted in one developing kidney and urethral issues and he had to be put down.
Or other 2 rescue females will eat anything but one got very bloated on this medication and vomited a lot. She's now not eating very much at all.
Damn you elanco. This product should be recalled.

Within 10 minutes the fleas were dead or almost. I love Comfortis. It was easy to treat my dog and it lasts the full 30 days. We had no side effects. I cant say anything negative. Excellent product. Thank you.

I used it for first time on my 13 year old and cat and he has been vomiting every since. Kitten is okay, he is 1.5 years old but after reading comments some cats have died would never use this product again

Beware..... my boy only had quarter of the tablet & vomited so much up after 1hr after giving it to him. Now after researching, this is common.....stay away from comfortis. This was the new chewable confortis green.

We gave Comfortis to our 8 year old, 14 pound cat. Within four hours she was dead. Do not give this product to your cat until you do your own research. This product is killing cats. I am sorry, Lilly. So sorry

I have been using Comfortis for over 7 years on my 11 year old schnoodle after my trusted vet recommended them. He has never had any problems or side effects. We had a major flea problem that would not go away. It was so bad at one stage that his stomach was covered with fleas and we were getting bitten as well. I tried other flea treatments that just didn't work. I have never seen a flea on him in 7 years.

I use it on my older cavaliers that I don't use for breeding, found it to be good but don't like products they have to digest but with nothing else working i have had to use it, would never use on my cat.

I like it for my dogs it works well

I have two 12 year old dogs Iv been using comfort
