I have read the study by Dr. Leder and agree with you. (I will also check the additional references provided by you). My initial thought was to remain on Prolia and to go to Reclast if future DexaScans indicate a further decline in BMD.

The original reason to use Prolia was replace the use of bisphosphonates (after a long drug holiday), which permitted correction of recurring dental problems at 6 month intervals. I am a devoted follower of Dr. Robert Marx. It was not until much later I found that Prolia was a "lifetime" drug. I have been at a high fracture risk level for many years, fortunately with no problems. Going to Forteo or Tymlos and returning to Prolia after two years seemed to be the ideal solution. Finding Dr. Leder's study, however, indicates this would indeed be a poor choice. Unfortunately, there seems to be no perfect solution.
