Make sure to tell your veterinarian what other medication or supplements you are giving your pet. Quite often your veterinarian may prescribe two different medications, even if a drug interaction may be anticipated. In this case, your veterinarian may vary the dose and/or monitor your pet more closely. The following drugs can potentially interact with phenylpropanolamine: tricyclic antidepressants, non-steroidal anti-inflammatory agents, halogenated anesthetic agents, ephedrine, chlorpromazine, monoamine oxidase inhibitors, reserpine, and ganglionic blocking agents. 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.
