@jennirdh Again so sorry all that happened. The medical world needs to get on top of this. It shouldn't be happening. With your ctx going up that much and with ibandronate being the med you were given the fractures you experienced are not surprising.

As best I can remember and verify in a few minutes of searching ibandronate is pretty similar in power to alendronate. Both are not safe bets for transitioning off of Prolia.
If your ctx had been tracked monthly and you had seen your ctx skyrocket you could have switched to Reclast immediately. That might have prevented your fractures. But there is perhaps no point in using anything other than Reclast to follow Prolia if you have been on Prolia for more than 1-2 injections? And still with Reclast I think we should be doing monthly ctx tests to see if it is stopping the Prolia rebound.
