Just a quick clarification on my earlier answer -- I mentioned I hadn't ever heard of intravenous bisphosphonates being used on a person with a normal DXA scan -- I should have specified, to treat osteoporosis on a person with a normal DXA scan. Medicines such as Reclast (zoledronic acid) are also used to treat conditions unrelated to osteoporosis (often associated with cancer) and such an individual might have a normal DXA but take the medicine for the other problem. Of course, that's unrelated to your question, but I did want to be as accurate as possible.
