@susanjane77 Prolia has a concerning rebound when stopped. You will have to do Reclast again to get off Prolia. Both are anti-resorptive so maybe bring an increased risk of atypical femur fracture or jaw necrosis with extended use.

Why does your doctor prefer Prolia vs Evenity. I hope you can ask about Evenity, Forteo or Tymlos after doing these years of Reclast. Evenity is also anti-resorptive in the latter half. All three will mean Reclast or Fosamax to lock in gains.

If your doctor wants Prolia after Reclast I would at least get a second opinion if possible. You could also consult with Keith McCormick, author of "Great Bones." My doctor, chair of endo at a major teaching hospital, doesn't use Prolia at all (unless absolutely no other option).
