    There have been a number of serious problems reported with these 'expanded dose' osteoporosis drugs, those that are dosed by injection every few months or years.

    I suspect that most of these will get added black-box warnings, and some might even be withdrawn from the market.

    The older drugs like alendronate/Fosamax, those that are taken by mouth once a week, have a somewhat better safety record, though long term use still has some serious potential side effects.

    John - I always feel that this kind of information should probably have been discovered BEFORE available to the public...never happy to post new warnings for a drug on the market...

    John-SKPT replied to Haylen_WebMD_Staff's response:
    Yes, we always feel let down when a new drug turns out to have bad side effects.

    But the newer FDA rules allow fast track approvals, which in the case of innovative lifesaving therapies might be a good thing. But the pharma companies take advantage of the newer rules to give them another few years to make bucks before their patents expire, even if a safer, more thoroughly tested drug is on the market.

    In many cases, the severe adverse events only show up after patients have used a drug for several years. Sort of 'we're damned if we do, and we're damned if we don't.'
