Both prednisone and Benadryl can cause side effects in dogs. Prednisone, a corticosteroid, may increase thirst and urination, lead to increased appetite and weight gain, cause vomiting or diarrhea, and suppress the immune system, making your dog more susceptible to infections. Long-term use can also contribute to Cushing’s disease.
Benadryl, an antihistamine, typically causes fewer side effects than prednisone. However, drowsiness, dry mouth, and mild gastrointestinal upset are possibilities. In some cases, excessive drowsiness or agitation may occur.
Always monitor your dog closely for any unusual behavior or changes in appetite, urination, or bowel movements while they are on these medications. Report any concerns immediately to your veterinarian. They can adjust dosages or suggest alternatives if needed. The combination of these drugs may increase the likelihood of certain side effects. Your vet can help determine the best course of action for your pet’s specific situation.
