I saw from another thread that you found Keith McCormick's excellent Aug 2022 OsteoBoston interview. You might also find his Feb2023 interview with Margie Bissinger re: osteoporosis medications helpful (https://margiebissinger.com/186-osteoporosis-medications-pros-and-cons-dr-r-keith-mccormick/). They discuss Prolia starting around 34:30 (minute:second). I recommend listening to the entire episode if you have time.

Personally, I find Prolia a scary medication, especially with its potential for a rebound effect if it is not prescribed or taken properly. I currently take Forteo (an anabolic medication, or bone builder) and will follow it later with Reclast, a bisphosphonate (which Fosamax is too, though Reclast is taken intravenously and Fosamax orally). It is my understanding the sequence of an anabolic (e.g., Forteo) followed by a bisphosphonate (e.g., Fosamax) is more effective than a bisphosphonate followed by an anabolic. I do not know if that changes depending how long ago you took a bisphosphonate before an anabolic.

I think you will find Dr. McCormick's "Great Bones" super helpful re: Prolia, e.g., starting at page 545 (it's a reference book, not leisure reading!) along with the resources teb and others have mentioned in various threads. If you have the financial resources, you may find a consult with Dr. McCormick very helpful too.
