DEAR DR. ROACH: I am an 85-year-old woman in relatively good health. I had been taking raloxifene for approximately 45 years. My doctor at the time said that since I had a complete hysterectomy, I should be on it for the rest of my life to help prevent breast cancer and osteoporosis. My bone density is normal.

A few months ago, my provider refused to renew my prescription because she was not familiar with the medicine. I would like your opinion on this decision. -- H.W.
