@car49,
I don't have any answers for you, but I looked up what discussion had been held on a2k about fossamax (you do that by putting the word in the small white google box at the upper right hand corner of the page and it'll show past a2k threads on the subject). I did get the idea that the drug may be not Fossamax, but Fosamax - I don't really know. But if you try to look the subject up on google or yahoo or elsewhere, you might try both spellings.
In the meantime, maybe someone else on a2k who knows more about the drug will see your question and respond.
