I took forteo long ago when it first came out. I lost all my hair --including on my body and face. I still have thin hair on head but they tried to tell me this was not a side effect of forteo - which now hairloss is listed as a side effect. You are truly having side effects from the drug. If you stop it -- I didnt- you will lose any gains but at what cost? Regardless, after the 1 year of forteo the loss starts again -- I lost any gains by now and never got the hair back. Its difficult to decide what to do and I feel your distress.
