I hope your doctor advocates for you, if your DEXA's are seriously low. Does your insurance still have the step program if osteoporosis is severe? Your doc should be able to explain the need for bone builders like Forteo, Tymlos or Evenity rather than the bisphosphonates. In fact the bone builders have been shown to work better when used first.

Prolia is not permanent. You just can't stop it without going on a bisphosphonate like Reclast, Fosamax etc. for a time. One poster here is doing one dose of Reclast OR a year of alendronate, after Prolia and posted a study n this in another thread.

When you stop Prolia, there is a rebound drop in bone density and increase in spinal fractures unless you do another med, possibly just short term. But you have to be careful about the timing of that switch- not too early and not too late.
