I am a 64 year old female who has just started on prednisone for Polymyalgia rheumatica. I also have osteoporosis and have just started Actonel (Risedronate). I have to take the prednisone and it can weaken bones. After reading all the side effects of Actonel and seeing there are law suits launched in US for side effects from this drug I am really wondering if I should continue taking it. Has anyone had any success with non-medication therapy? I have been using a weight vest when I walk for the last couple of years and maybe this has helped my hip bones but it has done nothing for my vertebrae. I am also taking calcium, vitamin D and magnesium.
