Hi... I am currently on Actonel for osteopenia, my bones were compromised by the chemotherapy and radiation I had for breast cancer. I tried Fosamax fist and had terrible joint and muscle pain at about the 3 day. Now my prescription company has switched me to once monthly Bonivia. I have been VERY sensitive to all the Statin drugs so am very careful about side effects. Should I be concerned about Bonivia and request to go back to Actonal?
