Rated 5 out of 5 by from I love this product. It can be pricey but it's money well spent. If your animal still itches, he may have a skin condition. Antibiotics Will help.

Rated 1 out of 5 by from Causes itchiness this product did in fact get rid of fleas and keep them from coming back. Problem is, now my dog is left with incessant itchiness. I called my vet and apparently this can be a side effect of comfortis. My poor dog. Now the flea itch is gone but she's still itching like she has bugs. Would not buy again. Waste of money. Especially since I had to consult the vet afterwards. Good fir ridding fleas, bad for your furry friends sanity!

Rated 5 out of 5 by from Effective and Safe I have used Comfortus for years and have never seen fleas on the dogs or cats. In addition, none of the pets have ever had an adverse reaction or side effects.

Rated 5 out of 5 by from Wonderful product! After a half hour of taking the medication the fleas died and fell off. Later after going outside I saw another flea dying on her coat and got rid of it. I’m very pleased.

Rated 5 out of 5 by from No more scratching! My Tibetan Terrier was on Frontline, but was scratching so hard that the fur was off his hind legs. At the vet, a flea dropped onto the examining table! Apparently, he is so allergic to flea bites that the Frontline didn't kill the flea fast enough to avoid problems. Comfortis solved his problem on the first dose. Fur grew back! He's been on it for 3 years now, with no problem. HOWEVER - I cut the pill in half, giving half after his food in the morning and the other half at night. That stopped his initial upset stomach from the dose.

Rated 5 out of 5 by from No fleas The pill was easy to give to my 9lb cat because it was fairly small. My 13lb cat was a little struggle and she threw up a few hours after the initial treatment but I think that might of been due to over eating. Cats had eaten kibble for breakfast, 30 min later given flea meds so u feed them wet food after because it says to administer with food. I'll evaluate the next dose with both cats and see what happens. The fleas were killed very quickly and now my cats are happy because they aren't itching anymore. I really like the ease of the oral administration and knowing that there isn't poison on the cats fur that my infant could possibly touxh. Also it's good to know if our little escapee gets out again she won't bring fleas back in the house anymore

Rated 5 out of 5 by from Works great I have been giving my Yorkie Comfortis for years now and have not seen the first flea. I even cut the pill in half and only give it to him every other month!

Rated 5 out of 5 by from It Works! The topical treatments are very difficult to give to my cat. She doesn't like them one little bit, and Revolution stopped working on her. The vet changed her Rx, but it was still topical. So we tried Comfortis. I crushed the tablet and mixed it with her wet food. She ate it right down. Problem solved. No fleas. I'm very happy with the product.

Questions

I give my dog her comfortis regularly and on time but I’m still finding fleas and she is scratching so much?

Asked by: Shoofly
You may have a situation where fleas are being brought into your dog's environment from elsewhere, such as stray animals or wildlife. Check your property and home for unwelcome furry intruders. Also, depending upon how long your dog has been using Comfortis, you may still have hatching eggs and cocooned larva which are getting on your dog for the first time and being killed by the Comfortis. If the fleas you are seeing are small and not the large adults, this is likely the case. Cocooned larva can survive for up to 2 years in the right environment. Your dog may also be scratching from things other than fleas. Dogs suffer from allergies just like we do but scratch instead of sneeze and get watery eyes. Consult your vet for possible allergy testing or treatment. Apoquel and Cytopoint are 2 excellent options for allergy treatment. Good luck!

Is there still Comfortis PLUS? If so, safe for cats?

Asked by: SusieQ
Comfortis Plus is called Trifexis in the United States and it is not labeled for use in cats. If you want to protect your cat from fleas, heartworms and other intestinal and external parasites, there are several options, such as Revolution, Revolution Plus, Advantage Multi or if you like Comfortis, you can add a heartworm preventative such as HeartGard for Cats or Interceptor.

My cat weighs 10 pounds. I crushed and mixed a 270mg tablet into wet food but my cat only ate about 3/4 of the food because he didn’t like the taste. What do I do now? Do you think he got a large enough dose for it to work? If not, do I give him more?

Asked by: Amie
You may want to give your furry baby more food to ensure the medication is effective.

What is Comfortis (spinosad)?

Comfortis is the first FDA-approved, chewable beef-flavored tablet (derived from pork protein and hydrolyzed soy) that kills fleas and prevents flea infestations on dogs and cats for a full month. Comfortis for Dogs & Cats requires a prescription from your veterinarian.

For:

Dogs & Cats (14 weeks of age or older)

Benefits:

  • Starts killing fleas within 30 minutes
  • Lasts a full month
  • Kills fleas before they can lay eggs
  • Comes in a convenient chewable, beef-flavored tablet
  • Spinosad, the active ingredient in Comfortis, is environmentally friendly

Comfortis is the #1 recommended Rx Flea-only medication for dogs and cats

How does Comfortis work?

The active ingredient in Comfortis (Spinosad) kills fleas by causing excitation of the insect's nervous system, leading to paralysis and rapid death.

Cautions:

Side effects may occur, including vomiting. If your pet is experiencing loss of appetite, lethargy, or any other difference in behavior, contact your veterinarian. The FDA has received reports of adverse reactions in dogs receiving the drug Comfortis (spinosad) concurrently with high, extra-label doses of ivermectin. Dogs receiving extra-label doses of ivermectin to treat non-responsive demodectic mange and other conditions have developed signs of ivermectin toxicity. Ivermectin is an ingredient found in heartworm preventatives such as Heartgard Plus, Heartgard, Iverhart Plus and Ivomec. In cats, the most common adverse reaction recorded in clinical trials was vomiting. Other adverse reactions were: lethargy, decreased appetite, weight loss, and diarrhea. Use with caution with concomitant extra-label use of ivermectin. For complete safety information, see product label.
