Comfortis is a beef-flavored tablet you give to your dog or cat to kill fleas and prevent flea infestations for one month. Comfortis chewable tablets are recommended for monthly use in dogs 3.3 pounds or greater, cats 2 pounds or greater and puppies and kittens 14 weeks and older.
Spinosad is the active ingredient in Comfortis. It belongs to a new novel class of antiparasitics known as spinosyns, which are derived from a naturally-occurring soil microbe. It works by attacking the nervous system of insects, causing rapid death of adult fleas.
Comfortis has demonstrated full effectiveness for an entire month.1 View a short video testimonial about the many benefits Comfortis offers.
Treatment with Comfortis chewable tablets can begin at any time of the year. Comfortis is most effective when given one month before fleas become active and monthly dosing is continued through the end of the flea season. In areas where fleas are common year-round, monthly treatment with Comfortis chewable tablets should continue throughout the entire year without interruption. To minimize the likelihood of flea reinfestation, it is important for you to treat all animals in your household with a veterinarian-approved flea protection product.
Consult your veterinarian for the flea treatment options most appropriate for your area. See also“What should I discuss with my veterinarian regarding Comfortis for my dog or cat?”
