I've taken daily calcium/D3 religiously since I was put on steroids but only took AA for about a month. I have no objection to it being used if there is evidence of loss of bone density but I do object to the concept of prevention is better than cure which, in fact, is now felt by many experts to be a false one. Over 4 years with at times quite high doses of pred my dexa scan is unchanged. It would have been 4 years of unnecessary AA - and that is approaching the maximum period it should be used without a break. Plus - it occurs to me - had I taken it what would that have done? There is a suggestion that the bone formed can be brittle because it has a different structure and is prone to atypical fractures - is that something that happens in bone that is actually normal but subjected to AA?
