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.

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 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.
