Cautions

The safety of Comfortis has not been established in breeding, pregnant, or lactating animals. Make sure to tell your veterinarian what other medication you are giving to your pet. Quite often your veterinarian may prescribe two different medications, even if a drug interaction may occur. In this case, your veterinarian may vary the dose and/or monitor your pet more closely. Contact your veterinarian if your pet experiences any unusual reactions when different medications are given together. Allergic reactions to medications may occur. Be sure to inform VetSource and your veterinarian if your pet has any known drug sensitivities or allergies. If your pet displays symptoms of an allergic reaction, call your veterinarian immediately or go to a veterinary emergency clinic. Symptoms may include but are not limited to: swollen lips, tongue, face, airways; difficulty breathing; agitation; profuse salivation; vomiting; widespread hives and itching.

Side Effects

Side effects may include nausea, vomiting, diarrhea, loss of appetite, and decreased activity. If you notice anything unusual, contact your veterinarian.

Usage

Comfortis should be given orally as directed by your veterinarian. If vomiting occurs within an hour of administration, redose with another full dose.
