  • Restlessness and intestinal distress (diarrhea and gassiness) have been reported with amantadine.
  • Using amantadine with antihistamines can exacerbate dryness, dry mouth, difficulty urinating, and increased heart rate.
  • SMZs (sulfamethoxazole/trimethoprim), quinidine, and diuretics can increase the absorption of amantadine, making potential negative effects stronger.
  • Do not use amantadine if your pet has kidney, seizure, or behavioral disorders, or liver or heart disease. Inform your veterinarian of any health problems your pet has before starting on amantadine.
  • Amantadine is relatively new to use in veterinary medicine. Any suspected side effects should be reported to your veterinarian right away.
