I have a 50% blockage in my right carotid artery. This scares me. I am told that as a 61 yr. old, this is normal accumulation. My cholesterol is not high (out of range)...172 Cardiologist prescribed Rosuvastatin (Crestor) 10 mg. I don t like taking any medication not necessary. I not see that a couple of my medications may be interacting. I am concerned about when I am supposed to take meds and which ones should be taken at different times in the day so they can do their job. I take Nexium, Atenolol, Levothyroxine, Super B, and 80 mg. Bayer aspirin. Now I have been told to begin Rosuvastatin. Please help me sort this out. My family Dr. is on vacation.
