I have been told that the two year limit has been lifted. Online I can only find the announcement for Forteo, which happened first. The Tymlos insert no longer has the black box warning and time limit. Double check with your doc.

The problem is that these meds stop working sometime between 1 and 2 years, for many. We need to have blood tests (P1NP, also CTX) to see if they are still effective.

I extended my Tymlos past 18 months even though it may not be doing much, because I need time to make decisions in the context of another new diagnosis. Otherwise I would have stopped at 18 months.
