I have read on the various discussion sites about side effects of bisphosphonate meds that hair loss can certainly happen (for some people). Which one are you on? Fosomax or Boniva? And for how long? I would advise you to go to a search engine, type in ''bisphosphonate medication side effects'' and check out the info that comes up. These meds can have many side effects (some of them dangerous, such as jaw-necrosis). They can also remain in your body, even when stopping them, for many years. I would give you a specific website to check out, but I'm not allowed to post websites here.

Best of luck.
