I have had a bad reaction to Fosamax; one years ago and again recently though it was called something else I experienced two migraine headaches and then looked up the drug on line and it was basically Fosamax. Now my doctor has prescribed raloxifine and I am leery of starting it. the side effects are pretty grim. I have taken Calcium and Vitamin D3 for many years. My last bone density test showed borderline osteoporosis. My next test will be in August 2019. I am 79 years old and in excellent health
