@smg22 I have read and heard that Forteo is ineffective after Prolia. McCormick's book "Great Bones" andDr. Ben Leder's videos on You Tube (including Sequencing and Combination Approaches to Osteoporosis" make this very clear. One person on this forum posted a study on Evenity after Prolia that showed it was effective in combating rebound though effectiveness was somewhat reduced (not as much as with Forteo!). Maybe the person who posted that can post it again.

It is true that both Prolia and bisphosphonates are anti-resorptive with similar risks. For that matter, the last months of Evenity are too. But bisphosphonates are most often used to combat rebound.

Prolia puts people in a bind unfortunately. I would get a second opinion if an MD suggests Forteo after Prolia or at least show your doctor the book or videos (I know that's awkward) or have a discussion.
