DEAR DR. ROACH: I am a 71-year-old man with a physically active lifestyle, and I have a strong passion to control my A1C and cholesterol levels by eating the right kind of food. I am taking metformin, atorvastatin and losartan to assist in controlling my blood sugar, cholesterol and blood pressure.
After turning 70, I was having difficulty being intimate with my wife. I requested my internal medicine doctor (a friend) to prescribe sildenafil, but he ignored the request. So, I turned to an online pharmacy. After answering a few questions, they dispensed 20-mg tablets. I determined that I needed 40 mg to assist me, and it has been working very well.
