Made both my cats very sick and damaged their livers – Gave both my cats this product once,to be sure I bought the lowest dose. My smallest cat vomited started shaking became really withdrawn had diarrhoea. My other cat vomited and howled in pain took both to the vet as they didn’t settle and remained unwell,both had many tests and the verdict was that these pills caused liver damage.my small cat had… Read more

diarrhoea daily for months. The cats were well before. Now both are on special diets because of the damage. Stay away from this.

Comfortis nearly killed my dog – This pill sent my dog into actue liver failure. It’s a miracle she survived. Not recommended. This is poisonous stuff.

Complaint – My little Maltese was well, I would never recommend this product it made my dog really ill, vomiting constantly, I had to take him to the vet and he is still ill today, Do not give this product to your pet, should come with a warning, I purchased the product from the vet as well, thinking I was giving him the best care, I then had to pay the vets… Read more

bill today, Disgusting, would never ever recommend this product. Look for a more pet friendly product..

Not yet sure if this is a good product-Who the heck makes these Tablets this size – Who the heck makes these Tablets? size of tablet vs size of cats mouth, had to break it in to four bit and feed it to my cat, tablets don't have break lines. It doesn't appear to have worked in 30 minutes like they said but my old wise cat did disappear 10 minutes after eating it so I wonder if he threw it back up. The cost for 3 tablets… Read more

is outrageous and found that only vets sell them in pkts of 6.

After reading other reviews I have to wonder why my new vet recommended this brand?

Will go back to the other brand where it is placed on cats neck next time and given the other reviews will not re use

Dog vomited 1.5 hours after dosing. Adverse events associated with dosing – My Chihuahua cross age about 12 weighs 3.9 kg. Healthy, active qualified therapy dog used to have Panaromis tablet monthly. Changed to Comfortis Plus by company changing product available. Vomited her stomach contents 1.5 hours after dosing (according to the product advice sheet) with tablet in her morning food. No diarrhoea and she did her usual… Read more

morning 1km park and street walk with her usual delight. I fed her as usual that evening 12 hours later. No vomiting and normal bowel action after that meal which was exactly the same as the morning meal with the addition of raw chicken necks from my supplier of chicken that is for human consumption.

Redosed her this morning as above and she vomited again. No diarrhoea. The vomiting is associated with the dosing.

I will not be using this or any other product from, or connected with Elanco. It is too expensive to waste money on a product that is ineffective due to adverse reaction to dosage.

I note with concern the deaths reported on this site after using this product. I will be contacting my Veterinary practitioner and discussing these events with her.

I note that the product formula has allegedly not changed from Panaromis to Comfortis Plus.

My dog has no intestinal abnormality. Kidney and liver function normal. She eats a consistent raw food diet with a reputable commercial product.

Recently seen by her Vet who examined her and commented "she is a strong healthy little Dog". Also recently seen by the ophthalmic specialist Vet for her second annual review of her Dry Eye condition. She produces tears and was again pronounced healthy.

Warning!!!! Do not use on cats!!! – Terrible!!!! Do not use for cats!! Our once perfectly happy healthy cat is now very skinny! She wont eat , shes vomiting and very lethargic and weak!! I cry just looking at her absolutely heartbreaking!!!! I thought she was dying! Never seen her so sick before! Do not use!!!! I've given her milk mixed with water and she is so keen to drink it but she is that weak she struggling to drink!

Cat was terribly ill – On Friday night I gave my 4.3kg two year old domestic cat Comfortis. He became very distressed and started panting with his tongue out. He made a strange choking sound as he breathed. I immediately took him to a vet hospital and the vet gave him an antihistamine injection and recommended I take him to vet hospital if his health degenerated… Read more

overnight. He was floppy and panting most of the night but eventually managed to sleep. He slept most of the weekend and didn't eat very much. He is slowly recovering but I won't be repeating that scary experience.

Scared for my cat – I gave this product to my cat last night for the first time after our local vet recommended it yesterday. The vet did not advise me of any possible side effects. Today the cat is very sleepy, floppy, lethargic. I AM SCARED>>>>> I wish I was advised of these side effects prior or read site. I'm terrified.

Killed my cat within 18 hours do not use! – My healthy 18 month cat had fleas. Took this pill and died 36 hours later. We found him dead in the basement. DO not use!!!!!

My beautiful friendly loving cat died from pancreatitis and organ failure within 1 week of taking th – Pancreatitis, diabetes and death within 1 week. Otherwise healthy cat. Vet believes the tablet shocked her little system so badly it caused her organs to shut down.

my dog had a seizure – Was using this product for a long while and it killed fleas great until one day my dog had a seizure, I raced him to the vet and they had asked if he had been given flea tablet which I replied yes Comfortis and he said that would have been the cause. I've stopped using it and try alternate natural treatments.

Not Happy! – Our maltese/silky cross has been on Comfortis (pink) for approximately three years. Over the last few months, the product has not worked. Took her to the vet as she has a flee allergy and had become very lethargic. As well as having flees, she had pancreatitis. She is home from the vet, but she is not herself and becomes very agitated. Clearly she… Read more

is still not 100% well, has lost weight and is not the dog she used to be. I know of two other people whose dogs are on this product and have the same problems. Reading this review web site there seems to be a lot of people having problems with Comfortis. As there seems to be many problems, am wondering if the company should do some research on their product.

Fleas are dropping off – Gave comfort is to my 2 cats this morning, the fleas are dropping and dying real fast. 3 year old cat doesn't seem to phased by it, but my 10 month old was panting like a dog, and seemed very agitated. He has calmed down now though, other than that the product works great.

severe health warning This drug causes liver toxicity for older dogs – My 13 year old male maltese terrier was given Comfortis tab and the fleas disappeared within the day. 2 weeks later he appeared to have a seizure and was quite unsteady on his feet later. He became lethargic and exhausted on mild exertion. he slept alot .I took him to the vet twice in the same day as he became increasingly breathless and… Read more

aggitated. Tobys liver function tests showed to be 5 times the normal. That night he died. He was a very healthy and active dog and had no health issues before giving him the comfortis. I warn people to be very cautious when treating older small dogs with this obviously toxic chemical.

Kills fleas! – A product that actually does as described on the box. It killed all the fleas within 24 hours and they only returned a month later. We tried many other products before this one and none worked from collars to powders to spot-ons and pills. None worked. This did.

does not work – My dog has flea allergies and has a big overreaction to flea bites scratching and cursing himself raw. Our vet recommended comforts since it worked well for others. It did nothing. I didn't see a reduction in fleas or his scratching at all.
