Second opinion doc yesterday said bisphosphonate is not that effective after Prolia. I did not discuss any further because I am not on Prolia but check it out before making a decision. I didn't get details and it is always possible I misunderstood.

Doc yesterday also discussed doing blood test bone markers while switching to a bisphosphonate to make sure timing is right- recommendation is to start bisphosphonate 6 months after ending Prolia, but if too early the bisphosphonate doesn't work and if too late, fractures from ending Prolia can happen.

Neither of my two (top) endos uses Prolia much anymore because you basically have to stay on it, according to the doc yesterday. She prescribes it for those who cannot tolerate anything else and for those who cannot take bisphosphonates due to kidney issues.
