I don't think our doctors know any more than we do about this drug. It's up to us to research it ourselves. According to what I've read, there is no evidence that even taking it at all prevents fractures, and there is quite a bit of evidence that it is in fact harmful. What's more, the drug stays in your bones even after you stop taking it and has a half-life of 10 years, meaning that it takes 10 years for it to reach half it's potency!! This, plus the fact that the long-term effects of this drug are unknown!! I have been taking Didronel, which is a weaker form of bisphosphonates for several years and was recently put on Fosomax because my bone density had gone lower according to the DXA test. I've now stopped taking it after having perused this forum, and reading an excellent book on the subject called "The Myth of Osteoporosis" by Gillian Sanson. All I can say is, I wish I'd read this material before taking any of these drugs. A very interesting fact that our doctors do not tell us because presumably they are ignorant of it themselves, is that bone density itself is not a reliable indicator of fracture risk. I've drawn the conslusion that our doctors are ill informed and we put our trust in them at our own (often considerable) risk. ******
