What is Comfortis for dogs and cats? Comfortis is the first FDA-approved, chewable beef-flavored tablet 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 How it works: 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.
