Information on side effects in cats and dogs are not well known.  Possible side effects include agitation, soft stools, diarrhea, and gassiness. At toxic doses, side effects include tremors, anxiety, incoordination, and increased salivation and vomiting. Other side effects may occur and may be based on the dose prescribed.  In some cases, a symptom may be an indication of a change in your pet's medical condition.   If you notice anything unusual, contact your veterinarian.

Administer as directed by veterinarian.

Make sure to tell your veterinarian what other medication you are giving to your pet. Quite often your veterinarian may prescribe two different medications, and a drug interaction may be anticipated. 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. The following drugs can potentially interact with amantadine: anticholinergic drugs, CNS stimulants (including selegiline), trimethoprim/sulfa, quinidine, quinine, thiazide diuretics, triamterene, or urinary acidifiers. 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; widespread hives and itching.
