PetMeds® Comfortis Flea Control: Potential Side Effects

 
Filed under Dr. Dym's Vet Blog
Did you know that not all flea control products for dogs are applied to the skin? Many pet owners prefer oral administration of external parasiticides to avoid exposure of themselves to topical pesticides, which is why some dog owners prefer the ease of administering a chewable tablet such as Comfortis. Comfortis can control fleas up to one month on dogs, but it does not kill ticks

Comfortis kills fleas within 30 minutes and lasts for up to one month. In my experience common client concerns include lack of efficacy against other external parasites such as ticks, as well as the need for written prescription from the veterinarian.

One of my concerns with Comfortis is the occasional wide range of side effects including vomiting and/or diarrhea and various neurological reactions ranging from incoordination, trembling, and seizures.  It’s for these reasons that I generally prefer using other flea and tick products in my practice such as Frontline Plus or Advantage II.

However, clients do report mostly high satisfaction with this product, with the exception of these occasionally severe side effects.  It is also important to still treat the environment for fleas, as well as incorporate additional measure to help control other parasites such as ticks if using Comfortis.

    Within a few hours of giving dog medicine she became very lethargic. Normally she is very active and plays constantly but not after this. She just laid around for about 24 hours finally started getting some energy back slowly. Wow bad bad smell and horrible breath to go along with this medicine which lasted about 3 days. The worst thing I have ever smelled. Will NOT be using this again.

    I gave our German Shepherd Comfortis tonight. Just returned from the Emergency Vet. Within a half an hour after eating the medicine, her back legs went out. She couldn’t walk. I’m sick over this. I’m praying she will be better \in the next couple days\ as the emergency vet said, as the meds get out of her system. They had to sedate her to do X-rays because we thought she’d broken her leg or her hips were in trouble. So, it remains to be seen. No…nothing broken, hips fine. Coincidence? I think not. I’m certain it was the COMFORTIS. Maybe she’s one in a hundred who gets serious side effects, but she’s one in a million to me and I am broken-hearted that she trusts me and I gave her this poison.

    Our dog was only 6 when he did last year from liver failure. We had him on Comfortis for most of his life. Has there been any association between Comfortis and liver problems? Our last dog (different breed) lived to 14 and we were giving him frontline.

    The Comfortis worked great as we live in a hot climate that produces both fleas and ticks. But before getting another dog, I’d like to have some answers to why our dog died at a relatively young age.

    No, not this time. We are very careful with our pets. My dog was running for a frisbee before she at this pill…perfect health. Had just had a physical recently. Three years old…in her prime. 15-20 minutes after eating this pill, her legs gave out! ABSOLUTELY NO QUESTION AT ALL. It wore off, thank goodness. Company realized issue. Reports were made to FDA. Company was concerned and helped pay emergency bills, etc. They realize this is a severe possible side effect, but I didn’t. My fault, as the consumer…I didn’t research it enough.

    I gave my dog comfotis and she immediately started scratching and her skin was very red. i thought she had got into something in the yard so i treated the entire yard with weed killer and pesticdes. She still has the same problem only worse. Took her to the vet today and they say it’s her thyroid. Didnt have any problems until she started taking this. Have you seen any side effects such as thyroid during use of comfortis?

    I am using Comfortis for the 2nd month with no side affects, but limited success. I increased the dosage the 2nd month, because my dog is borderline 40 lbs, still no side affects, but she is still scratching and chewing, however, not as much. I have never had a flea problem until this year and am trying to vacuum and keep the house free of any larvae, eggs, that may be inside. Still
    the scratching and chewing is driving us, both, nuts.
    Any suggestions on anything I can put down in the house and bedding to help kill any fleas that may are hatching after I started treating her? Or should I try a topical flea killer on the dog instead of the Comfortis?

    [Reply]

    Dr. Michael Dym, VMD veterinarian Reply:

    I would try oral program and capstar from 1800petmeds. Also consider flea busters for home which you can find on line.

Other dog is extremely lethargic and won’t eat. If they do live thru this, I will NEVER use it again and if they don’t make it… I wish I could sue. I am furious and scared.

    My older dog was given comfortis on Dec 28th after dinner.

    He started throwing up at 2:45am Saturday morning.

    He is so sick right now, and we can’t seem to make him feel any better.

    Have been to the vet 3 times in 3 days…sub q fluids, cerenia
    Homeopathy, etc.
    His liver & kidney #’s are normal waiting on pancreatitis

    Hoping he will turn around…but I am worried sick myself.

    It’s been 48 hours, and its not getting any better.

    Dr. Michael Dym, VMD veterinarian Reply:

    HI Holly: Sorry to hear of your dog’s problems after comfortis. Probably best to consider IV fluids at vet office for a few days until symptoms calm down. What type of homeopathy was given? You may want to consult with a classical homeopath, which prescribes remedies based on constitutional symptoms. To learn more see http://www.doctordym.com

    I gave my 14 year old AmStaff her first dose of Comfortis almost 24 hours ago and I am happy to report that she did not have any visible side effects and even better than that, she doesn’t have any fleas! When we lived in NY Frontline was all that was needed and it was moreso for ticks. I had never seen a flea before moving to FL. Frontline, baths and herbal remedies were to no avail. Comfortis seems to be working like a charm.

    I used Comfortis for my 3 German Shepherds. Loved it at first, no fleas whatsoever. After a few months of taking it, all three started having seizures. They all started to refuse to eat it. Took them off the Comfortis, and it took 6-8 months before they quit having the seizures. Now just trying to find something that will keep the fleas away. Going to try the Seresto Collar. Hope it works as well.

    Most oral pesticides such as comfortis are fine to use in most dogs. In sensitive breeds, chronic pesticide use may be linked with chronic diseases, although hard to prove.

    oh my gosh, I just thought my dog was going to die. she has never had a seizure in her life and I gave her one of these comfortis pills this morning for the first time and she just now had a huge seizure. I really thought she was going to die. and now she can’t hardly get up or stand up. I have been crying my eyes out and I just feel terrible. she also peed all over the floor. it seemed like she was never going to come out of it. I hope she can walk tomorrow. terrible just terrible.

    I have had my Senior Doxie on Comfortis for three years and all year long. i see the relief that my dog gets in a short period of time and she stops scratching and chewing. i have not seen any bad side effects with this oral medication. it is far worse to expose the dog to flea shampoo and then a toxic flea collar and still see fleas. my vet sells me the pills and matches the doseage to her weight. i reccoment this to dog owners.

    Waching your dog have a siezure is frightening. They cannot tell us that they feel odd, or their stomach is upset.
    My spelling was terrible from my last posting. Dogs and cats bring fleas into the house and we carry them in on our shoes. The key I think is to stay on top of them from the start. My dog got fleas after I kept a friends dog with me for four days while the owners went to a cutting horse competition. Harley had fleas and I did not think about it. I let him sleep in my bed with me and my dog. After I returned Harley I spotted the fleas on my dog. I did the flea shampoo thing and did not know Comfortis existed. My neighbor came over and we sat on the floor picking fleas off of my dog and dropped them in a cup of water. Fleas cannot swim so they sank to the bottom of the water cup. I am looking for a natural flea spray that I can use on my dog and on my bed. Any ideas?

    I just purchased Trifexis, it’s a monthly tablet dogs/cats take to kill fleas, protect the heart and kills any intestine worms. Gave both my dogs this last night, checked them this morning and the fleas are DEAD!!! Amazing product. You have to be careful with the others because they kill the flea larva but not the flea…the flea will continue laying eggs and you will never get rid of them. Trifexis is expensive but well worth it.

    The first few times that I pilled my Doxie Gretchen with Comfortis she gobbled the tablet down like a starved animal. I had to start asking her to do something for her “treat” and that lasted..a while. I progressed to wrapping the pill in cheese. as she watched. That worked once. I bought liver sausage and stuck her pill in that for a few months. It has gotten to the point that her and I struggle to get the pill in her mouth and I hope she swallows it. She gets a real treat if I do not see her hack the pill up onto the floor! I have wormed a horse with less trouble. I end up all sweaty and my hair sticking up. She is 15 years old and thinks she is Alpha to the planet. What gives?

    [Reply]

    Dr. Michael Dym, VMD veterinarian Reply:

    I am concerned that her body may be reacting to the comfortis pill when I see a pattern like this, especially in a breed like a doxie which is very sensitive to drugs, chemicals, vaccines, etc. She is probably learning through repetitive doses that she does not feel so well after taking it, which can be seen with any pesticide in elder animals. Maybe consider an alternative flea control product in pet this age, even a natural option like flea free from 1800petmeds.

    I have seen rare neurological reactions to any of the oral or topical pesticides. hard to say if seizure disorder was caused by product or just a pre existing tendency was already there. Best to see vet for exam and evaluation to see if anticonvulsant meds may help. Also could consult with a homeopathic vet to try and raise level of health over time.

    My senoor Doxie does well on Comfortis however I am wondering if she is building up a tolerance to the drug. I find a flea or two on her. i purchased flea busters and should get it in a few days. I also purchased an organic flea powder that can be used on my dog and her bedding. She starts her day with a benedryl type pill that gives her relief from the itching. My Vet says that she is allergic to the flea bites. I have a topical spray that I use to stop her itching in one area. I am interested in massage therapy for my senior doxie….just because I love her. BTW flea collars are highly toxic!

    I gave my 4yr old Chihuahua her first dose of Comfortis @ 4 pm yesterday. She got rather hyper and paranoid … She followed me everywhere. She also ate a lot. Instructions said give with a full meal but she kept eating afterward. Today she had a small normal consistency poop, and this evening some diarrhea. Otherwise she is active and happy. I hope it works since she gets FAD really bad every year when it gets warm and we have to go to the vet for Simplicef and Temeril-P.

    when in southern california, vet prescribed Comfortis for 10 lb and 15 lb chihuahua mixes. i was amazed how much they scratched soon after application, and was told it was the fleas coming out of their skin… already dead… and that this would kill adults and larvae and eggs alike. i put the pill at the back of their tongues and held their muzzles shut until i knew they’d swallow it… pretty easy with the learned technique, and very clean.
    … since then have moved to the mountains of arizona, where vet prescribes topical Frontline. i’m not sold on this product. just returned from visit to the beach in so cal, and came home with poor itchy pup. an oatmeal bath has not eased his discomfort.
    … it’s been only 2 or 3 weeks since last application of Frontline. i’m here to order Comfortis once again. i’ve never experienced side effects mentioned by others (my sincere sympathy), and have visible results within hours of dose… even though it’s a bit disconcerting to see them scratch like crazy for a while.

    Add me to the list of having a dog who quite likely had an adverse reaction to Comfortis. My 13 year old Border Collie had severe vomiting and tremors approximately 5 days after receiving Comfortis. The tremors became uncontrollable and progressed to the point where she could not walk. We really thought we were going to lose her. After rushing her to the ER to be stabilized and monitored, along with a follow-up consult with a neurologist, we were unable to make a positive dx. The one new factor in her life was Comfortis. After taking her off Comfortis, she is now completely normal 3 months post the tremors/neurologic episode. Was I informed by the neurologist of a possible connection to Comfortis? Nope, he only wanted to do a spinal tap and an MIR….Positive conclusion? Nope. Will I ever give her Comfortis again. H NO!!!
