I've been avoiding starting weekly Actonel. I've read that biphosphonates stop osteoclasts from cleaning up the old bone. So osteo blasts alone work ( which build bone) the problem is the drugs stay in the bone /body for many years so the user is left with old bone. Whilst it gets denser it can end up old and brittle in quality and break easy. So short term gain can result in longer term problem. I'm just reticent to take any and worried about it all. What to do ? And women still seem to be told half of the information we should hear. Interested in everyone's input.
