If you stop Prolia you will need Reclast. But if you stay on Prolia, that's a different story. Depending on age, at some point you may have to get off Prolia. Since both Prolia and Reclast are antiresorptives with long term risks, maybe you can ask your doctor if those risks are cumulative with the two meds or separate with each. I would love to know what your doc says.

By that time maybe Evenity will be okay after Prolia but would still require Reclast at one year, and that is basically three anti-resorptives total (Evenity is both anti-resorptive and anabolic).
