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