I have had a runny nose, watery eyes, sneezing and coughing since yesterday. I took an Aller-Tec capsule, a 25mg diphenhydramine HCL, and a 600mg Ibuprofen at 7:00 PM. I was going to take 2 more diphenhydramine before going to bed. I am also taking a 500 mg Bactrim prophylactically (recent urethral dilation and catheterization), 2mg Warfarin Sodium, 300 mg Gabapentin, and 10 mg simvastatin. I am concerned about possible interactions/overdoses and I would appreciate your thoughts.
