I was told by my pharmacist that taking 120 mgs diltiazam and 40 mgs simvastaton, as well as 200 mgs amiodorone and 25mgs metropolol can affect my body negatively. In addition to those meds I take 40 mgs furosemide 10 meq potassium twice daily, 100 mgs sertraline, 1 mg alprazolam twice daily as needed, 100 mgs trazodone, and 2mg warfarin. I have rheumatic heart disease. Had my Mitral Valve repaired in 2005, and had a cardiac ablation which took 6 hrs this past February. I'm feeling concerned about the many meds I take, and the possible conflicts. Can you advise?
