@gravity3 I believe I have been told Reclast is taken 3-5 years. Prolia can be taken 10 years or longer? (I would check "Great Bones" if I could find it!). They are both anti-resorptives as you know so I would wonder if the anti-resorptive effects are additive, meaning how different is it to do Prolia after alendronate (previous to Evenity) vs doing more alendronate in terms of things like dental issues or atypical femur fracture. And of course you will need Reclast when you stop Prolia. If any of us are in our 80's, Prolia can be taken for the rest of our lives so that solves the rebound problem! Otherwise, McCormick recommends 2-3 Prolia only then Reclast.

Have you discussed this with your doctor? They can no doubt answer your question as to why Prolia and give you a long term view of what is ahead.

gravity3,
Both my endocrinologist and my rheumatologist said Evenity. Neither ever mentioned Prolia. I was glad they didn’t as I had heard more complaints about Prolia than any other drug.
