I Was Given Prescription For Evista To Help With Bone

I was given prescription for Evista to help with bone loss. I am 68 yrs old and had polio at age 6. I am a very active person and get around good for my handicap, even wearing a leg brace. I am not for sure if I really want to start taking this med after reading the comments and the pamphlet with the med. In the past I was given the Fosamax to help with bone loss and only took ONE pill and had severe muscular and skeletal pain. Does Evista have any of ingredients that Fosamax has? Thank you, Belva
