Comfortis Tablets Orange (For Dogs 18.1 - 27kg, For Cats 2.8 - 5.4kg)

I wish I could rate it negative 5 – Within hours my old cat was given 1/2 tablet, he was not able to move - experienced symptoms of ataxia. We took him to our vet and numerous tests were done but all came negative. He was put on steroids and initially improved but never fully recovered and died within a few months. Had I known what I have learnt since, I would have never given… Read more

Comfortis to him of course. I would have not taken him to the vet either and instead I should have applied chemical detox drops about which I only found out when it was too late.

Killed my cat not the fleas – This is a highly poisonous product, was given by the vet to use on both of my cats, one of which vomited immediately, the other was unable to breathe 3 hours later and passed away. Now one is left without his friend forever. Show details

Killed fleas and my cat – We’ve given our 11y/o cat Comfortis two times in years past. Last night we gave him a dose. He went from healthy, happy and normal to dead in 8 hours. Show details

DO NOT USE THIS PRODUCT – Gave Comfortis to my darling girl and within a few hours she passed away. Just wish I had read these reviews beforehand. I will regret this for the rest of my life. How can such a toxic product be in the market?  Show details

Makes cats sick – Makes cats sick. They vomit every time. Sometimes within an hour, sometimes later. But every time. Cats hate it. They do not chew it like a snack. Not worth high cost. Ineffective. Company is indifferent to concerns. Took a lot of information, but refuses to do anything. Thus, wasting my time as well. Show details

A Game Changer – I read a lot of reviews and researched this product for hours. I was worried about the side effects and the horror stories of people losing their pets after taking a single dose. I have two Siamese cats, one is two years old, agile, powerful and weighing in at 12 lbs., the other guy is 9 months and easer to control, he weighs 7 pounds. The little… Read more

guy contacted fleas at the vet during his neutering and eventually I had a full infestation in my house. I tried a number of products, advantage drops, flea collars, Adams cat flea spray, Raid Carpet/Upholstery spray, Ortho Flea indoor home spray. I bombed my house and used other products including home remedies. I watched a couple of videos on how to give your cat a pill and it took me about 20 seconds to administer, even the big guy made it easy for me. There were absolutely no side effects, I guess I got lucky. I flea combed both cats 4 hours later and found several dead fleas under their fur and a few in plane sight. I found throughout the next several days one or two dead fleas on the cats and the areas where they hang out and sleep. I found no living fleas and eventually no dead fleas in my house. I continued to treat the house emphasizing on getting rid of flea eggs and the other stages of the flea cycle. The bottom line is that for my cats this product worked as advertised and my cats handled the drug well. I won the war!

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... Show details

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… Read more

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… Read more

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.

Product is brilliant – Ive been using this for 7yrs. Was previously know as panoramis. My dog never has fleas or worms. Never had side affects. Digests it well. It last longer than a month. I use it every 6-7 weeks. Show details

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.

Flea free finally! – My three cats and my house had a heavy flea infestation after the recent weird Melbourne weather, they exploded everywhere, gross! We'd been using revolution and I've always found it hard to spot-dose correctly so the poor cats were probably missing out. They were stressed and sick with flea problems 10 days after their last revolution dose. I… Read more ·  1

asked the vet and used Comfortis. I made sure they had a full meal with the tablet crushed in it and they chowed it down. After about an hour a 3 hour long, 3 cat grooming frenzy beganbaa the fleas started dying, but there was no vomiting or any other distress shown by the cats. The next day I flea bombed the house too using a Raid bomb and washed all their bedding, and mine! I noticed that evening that where the cats had been sleeping stayed clean, no flea dirt scratched out, just a few dead fleas. Three days later the cats are flea free, relaxed as only cats can be, shiny coats and appetites are back. It's been truly great and being aware we've had that infestation I'm keeping an eye out because I know sometimes it takes a a few cycles to really break the flea cycles but so far the house is clear of them and so are the cats. Just for reference the cats weigh 2.8kg, 3.3kg and 3.8kg respectively and they each had a full tablet.

Dangerous product – 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.

FANTASTIC FOR MY KELPIE – Worked a treat on my dogs fleas, the fell right off him within the first hour after taking it. No side effects. My kelpie loves is and eats the chew right out of my hand (he isn't easy to trick with tablets normally either). Would recommend.

My cat is TERRIBLY sick! – I got this from my vet for both of my cats a few days ago. My 4-year-old, female, 10-lb. cat seems fine. However, I gave the dosage directed for my 14-year-old, female, 10 lb. cat, and things have turned out very badly. She immediately started losing control of her bladder and urinating all over the couch. She is weak, disoriented, and cannot jump… Read more

up or down from the places she normally lays. While walking, she struggles to not fall over. She is still eating and drinking. When I took her to the litter box last night, she used it, but then stayed there and slept in the litter box all night. I think she knows she cannot control her bladder, because cats are so intuitive and clean when it comes to toilet habits. I don't really know what to do, and I am praying this does not get worse. I feel TERRIBLE that I did not research this before giving it to her, as there are SO MANY warnings here from other cat owners. Don't use this product!

Did exactly what it stated it would – I have a 9 month old Sibirian Husky and i have tried multipul different drops for fleas on my fur baby and it just didn't work! The fleas were getting so bad i could see them when ever i looked at him. Then he got fixed and the vet noticed how bad they were so she suggested Comfortis as it was what she used for her dogs. Within the first half hour… Read more

he started figgiting a bit then with in the next few hours dead fleas just dropped off of him! Heaps of them! the next morning we woke up and inspected him really well and couldn't find any except for the tonne on the bed where he slept. Its been a week and and there are still a small few of them around in the carpet but once they land on him they are found dead shortly after. Im very happy with the outcome, the packet warns that occationally it can cause vomiting in the forst couple of days but we never had that problem. I suggest if you are looking for something that works and the drops don't, then try this stuff!

I was very skeptical of putting this into my dog's body especially after readinf some of these comments but Im not sure if they are legitament and if so they may have just been unlucky.

Minor risk for big results – We have used Comfortis on our kelpie X and couldn't be happier having no side effects whatsoever. We had tried Frontline+ with no results at all, if anything there were more fleas in the following days after applying the Frontline+. We then decided to change to Comfortis after much researching and we're delighted when dead fleas were falling off… Read more

him within hours of his first dose. Six months later with no follow up and he is still completely flea & itch free. As this product can have a bad interaction with other medications in a small percentage of animals it's worth doing the research first to be sure your pet will not be affected. It is also extremely important that Comfortis is taken with a full meal. All things considered I think Comfortis is definitely the best bang for your buck (Bravecto is apparently great too but is very very expensive). My research showed animals who react badly (although only a tiny percentage) are usually are due to incorrect dosing/application, a certain gene found in herding species which can be tested for before use or the result of other drug interactions. Best of luck.

Best Flea Meds... ever... I love this product – I have used this product for 5 years with my small dog... She is about 12 lbs. I have used once a month for over 5 years, I have her Vet check her blood work from year to year so I know she is in perfect health. I have never had any trouble with this medication and highly recommend it!

The taste is the only issue – Okay have used this product several times works great. Only issue the taste. My cats and brothers dog hate it. It's great for dogs as you can stuff it in some food and they will eat it. Cats however won't touch it. I have to get the Vet to stick it down their throats. Works well but they seriously need to fix the taste. That's the… Read more

only issue.

As for the stories of sickness and death I have used this product a few times on my three cats and my my mum's dog all were fine never an issue.

My mate used it on his two dogs were fine so I'm not sure if the comments are legit or just trying to scare people.

Perhaps they like another brand won't to tarnish others not sure I've never had an issue nor the people who use it.

My cat vomits if she has it – My cat absolutely hates this stuff. I have even given 1/2 tablet with food and within 10 minutes she vomits. I phoned the company and they said to give it another attempt the next month and if she reacted the same they would refund my money. Well I have received no reply to my message on their answering machine.

Great for killing fleas but side effects very worrying – Gave my dog comfortis at 9 pm and by 2am extremely lethargic and her body was trembling. She held her head upwards and kept it in that position also she stretched her paws in the air and held them there as if she was playing statues. After a couple of hours the trembling stopped and also the strangely held limbs. Great for fleas but I won't risk it again.

Love it – Love this product. My dog has a bad reaction to flea bites so this fast acting product is great. She has never taken the tablet without it being hiden in food and no noticable reactions after taking it.

The only effective flea treatment i've found – Last year my cats and dog were rampant with fleas, despite using Frontline, Advocate and a range of natural products and household flea bombs. I finally tried Comfortis and have they have all been virtually scratch free ever since. None of my pets have had any adverse health reactions thankfully, something I was very worried about given the… Read more

potential side effects, they'e all been fine (the smaller cat does seem a little more sleepy but this soon wears off).

The only downside is how difficult it is to get the tablets into the cats crushed up in their food, given that they leave their dinners, swap dinners, and finally the dog will finish off any scraps if unsupervised. So he's definitely gets a full dosage at least!

It's for my bitza – It has worked for the 24 to 28 days for my dog each time. Has had no problems, weighed it so I used the right type for my foxyx which is orange. If you don't weigh the dog or cat it can cause problems I was told my vet. Capstar, front line, ect all seem to have no effects on fleas or bad reactions to my dog. Use the instructions on the boxes for all animals as the recommendations are there for a purpose, is safety of your pet.

My dog is smart! – After reading some of these horror stories, I now understand why my dog refused Comfortis. This is the second season he had it and the first time it seemed to go reasonably well. This time he just would not swallow it and even responded badly to the smell. I finally coated tablet pieces liberally with peanut butter and he swallowed (with suspicion… Read more

as the smell was still there) but he vomited it all out several minutes later.

I won't be using it on him again.

Very Dangerours Russina roulette – I cant recall the color of the packet as comfortis was new, we gave both our fox terriers comfortis. We came back home to find one of the dogs was having a seizure, we thought it was a snake bite, our other foxy was fine. It wasn't a snake bike it was the comfortis. I was just looking at the reviews and thought it pertinent to put my story on… Read more

the review. I made inquiries with the company etc, with no response. I did search the internet and this is simply a poison, I know all flea treatments etc are, but this is dangerous, our dog suffered because of this product. I WILL NEVER TAKE THE RISK WITH THIS PRODUCT EVER AGAIN.

Wanna kill your pet--then give it Comfortis – Three days after giving Comfortis, my dog lost all use of her limbs, her spine was completely paralyzed, her pupils dilated, she could hardly breathe, and by the time we reached the vet, her jaw was locked and she was fading fast. I had given Comfortis to my dog before, although infrequently. She had thrown up, had diarrhea and was lethargic, but… Read more

stupid me, I thought that the product worked so well and that the side effects were minor. I had no idea that it could get this bad, that I was poisoning my dog and Comfortis would eventually kill her. Perhaps healthy, young dogs can withstand the effects better. Perhaps there was something else going on inside my seemingly healthy 8 year old Boston Terrier that I was not aware of. Whatever happened, I can say that Comfortis killed my dog. All these warnings are on the label, except they left out the fact that this is a serious neuro-toxin and can also cause death following the symptoms. Here's what it says on the Comfortis website: For dogs: The most common adverse reaction reported is vomiting. Other adverse reactions reported in decreasing order of frequency are: depression/lethargy, decreased appetite, incoordination, diarrhea, itching, trembling, excessive salivation and seizures. Following concomitant extra-label use of ivermectin with Comfortis, some dogs have experienced the following clinical signs: trembling/twitching, salivation/drooling, seizures, ataxia, mydriasis, blindness and disorientation. They forgot to mention that these clinical signs can kill your pet.

Comfortis kills – Comfortis led to my dog's death!!! Was recommended by vet and my dog was on it for two years!! in June of this year I gave her a monthly dose and four days later she was dead ..three days after the dose she got seizures and was unable to move her legs!! After high vet bills she did not improve.. I took her home.. Loved on her then made a decision… Read more

to put her to sleep.. The saddest day of my life!!! Please do not give this poison to your furbaby!!

Fantastic – This was recommended to us by our Vet. At almost $100 from the Vet, we bought only once, but have bought it on-line since at almost half the price! We can tell when it starts to work as the poor pup (dog), which has been scratching because it has worn off (because we forget to give it to her on the right date) starts scratching even more as the… Read more

fleas start moving around her body, and then - miraculously (well, to us,and probably to her), no more scratching. Fleas all gone, and we have a happy pup. Great product.

Rubbish! Dont Waste Your Money – I asked at petbarn which is the best product to kill fleas on cats and they said Comfortis was so I paid almost $80 for the 6 pack of chewable tablets. It's been 1 week since I treated my cat and he is still covered in fleas. So pissed off! These 5 star ratings on here seem fake to me, don't be fooled.

Fantastic! Best flea product ever! – We just moved house and our indoor cat went under the stairs which led to underneath the house. Being an indoor cat she has never had fleas or ticks. Two days later discovered flea dirt on her white fur and saw fleas running on her head. Bought Comfortis the next day. Haven't seen any fleas since!! Very happy!! Thanks Confortis

Wonderful product – Helped my pup in more ways than one, got rid of the flees and helped with his skin allergies, Havnt found any other product that suited my pups and had the same results.
