We gave Comfortis to our cat yesterday morning and we found him dead this morning. He was healthy and only four years old. He was the best cat ever and we are heartbroken.

KILLED MY BELOVED CAT!!
Just three days ago, I gave my cat the second round of this medication, exactly a month to the date. 4 hours later she is contorting on the floor, unable to breath and died within minutes in the car on the way to the emergency vet. I am heartbroken and distraught. Our family has been torn apart by this 100% preventable tragedy. Please, trust the reviews and do not buy this product. Do not risk their lives. I will forever regret and hate myself for making her take something I thought was going to help but instead ended her life.

Too poisonous for my cat
We gave our cat comfortis, never again. She was really lethargic for 2 days and her fur was dull straight away and still is. She also has been acting weird since, I almost think it's affected her brain... It's been a week and she still has fleas...

DO NOT USE EVER
My 1 year old 24lb cat and my 8 month old 10lb kitten both were administered one tablet each by my husband and I, my oldest immediately started to swell up in his whole face. It was swollen by day 2 like he had been stung by a bee and had an allergic reaction about the size of a cantelope. Considering his weight should have been double the dose I gave him according to the package I am glad I wanted to try one for now & see if it works fine and I'm sure if I would have givin the correct dose he wouldn't be alive. Less then a week later his neck ...looked like he had been attacked by a huge dog (he hadn't been attacked by anything) it had spread from his face down to his torso. It was a 6in by 3in bloody & raw, deep gash. As he couldnt stop scratching it , the fleas would have been way less of a problem from the beginning to have dealt with myself. Now a month later along with a lot of bandaging and benedril to not only stop his itching but to sedate him in order to keep him from injuring his self even more, he finally had his hair grown back and I just now thought to read reviews before trying one more time but NEVER will I EVER give them this lethal and obviously dangerous "medication" again. I will bathe them everyday and use a flea comb likeni initially did with my husband taking turns every night if that means I can keep them from going though the horrific nightmare we have all gone through these past 4 weeks ever again. And yes little man was perfectly fine but just because it wasn't showing on his skin I'm well aware of the damage it could have done to his insides and I dont care if it did nothing this one time after seeing these horrendous reviews and the hours I've spent keeping kitty Cobain (the older cat) basically wrapped up like it's winter with literal baby clothes to keep his bandages on in this florida heat I'm sure over a long period of time something horrible would have happened to Mink too. Please find other means of insecticides to relieve your pets itching this will only make your problems escalate far beyond necisary in order to keep flealess pets.

Avoid at all costs
Within 30 minutes of giving our cat half a Comfortis tablet she was running
round the house, unable to breath, her eyes were starring and she kept
falling over. We immediately rushed to the vets where they put her on a drip
and gave her steroids. Later that evening she was transferred to an animal
hospital and monitored overnight. It took 3 to 4 days to recover but she has
been left totally deaf. I cannot understand why this drug is on the market
and being sold by vets.

Thought our dog was going to die!!
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!

NEVER EVER USE THIS PRODUCT
my dog had wobbles and was paralyzed day after taking this, with a 60kg dog this was product that killed him, he could never walk again, don't risk using it, use any other product, this should be removed from all shops.
Purchased for $50.00.
No star if I could
Can't coordinate his limbs and walking is like he is drunk all in less than 12 hours for the dose which was administered in accordance with the instructions.

Still has Fleas
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
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
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!!!

DANGEROUS PRODUCT!!! DONT GIVE THIS TO YOUR DOGS!
Gave my 30kg Rottweiler the Comfortis plus brown with her dinner. The next morning she wasn’t herself her nature was that of a HEAVILY SEDATED DOG! Rushed her to the vet.... extremely bad reaction to this oral treatment. While she was sick I researched and saw all these reviews! I am so so so thankful that my girl pulled through her blood tests where great and I’ve dropped in her urine sample this morning. Will be doing another blood test in 4 weeks time to check again. I honestly thought my dog was going to die. Most awful & scariest thing I’ve ever seen with a pet. THIS STUFF SHOULD BE ILLEGAL ITS POISON!
Comfortis does not work any more.
I bought comfortess for my dogs.it has been several days now.they still have fleas.i have 3 skye terriers that weigh around 27 lbs. A mixed breed that weigh around the same. 2 salukis that weigh around 40 or cfc50 lbs at the most. I am not pleased.
almost killed my cats
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 :(
Our two year old Border Collie had a seizure the day after taking his first and last oral flea product known as Comfortis...he remained epileptic for about 4 years and now hasnt had a seizure for nearly 2 years, we put him on a raw food diet with golden paste and he has had acupuncture...we believe this might have saved him.
Heathy 58kg male dog. Bloody Diarrhoea and lethargy for a week after taking comfortis plus. Had no problem with it before it was rebranded (previously panoramas). I’m glad I only gave him the one tablet and didn’t top up to his full weight after reading these reviews. Have thrown the rest out and spoken to vet about the side effects, vet suggested I change to something else. I’ve also been warned against Bravecto
My dog died within 4 days of ingesting this poison
Two healthy dogs, 47kg female and 54kg male, gave tablet Wednesday and female throwing up within a couple of hours, vomiting and lethargic for two days and rushed her to vet on third day too weak to stay upright. Diagnosed with acute Liver failure, on drip for day and a half and had a seizure, liver, pancreas, failed, glucose levels extremely low, internal bleeding, bloody vomiting and diarrhoea, PTS four days after ingesting this supposedly safe poison. Thank God the male was only a bit lethargic for a couple of days and seems ok.
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.
Healthy 16 month old cat died after giving comfortis
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.
Questions & Answers
My 13 lb. dog had 1/2 comfortis pill 2weeks ago. Can I give her a sentinel pill (her usual monthly flea tick and heart worm med) now?
price for comfortis orage 6 pak?
I was given a litter of 6 to 7 week old kittens. The person said she crushed up the smallest size comforts for kittens (4.1lbs or 14 weeks) and have each kitten (5 of them) a small amount. Should I panic or will they be ok?
Elanco Comfortis can cause severe reactions when it comes to flea prevention
Elanco Comfortis is made to prevent flea infestations in both cats and dogs who are 14 weeks and older. Elanco states that the product starts killing fleas in 30 minutes, allowing you to ‘simply treat and play.’
It’s important to note that for several reviewers, administering this medication to their pet caused concerning side effects such as illness and even death. This sometimes happened the first time a tablet was given, and when pets were young and healthy.
Even though some flea medications may be vet-recommended, adverse reactions are a very real possibility with these tablets.
Other reviewers who gave Elanco Comfortis positive reviews did so because their pets didn’t experience any negative side effects.
A number of these positive reviews were written in relation to pets who suffered from an existing flea infestation - rather than flea prevention. However it can be hard to predict a reaction, so it’s advisable that the medication is given to pets with caution and careful monitoring.
