dawhitacre1,
You've decided to quit Prolia.
It is fairly standard to start Reclast after Prolia. It is the best medication to prevent rebound after Prolia. But it has its own set of side effects. Some people fare well with different bisphosphonates of lesser strength like alendronate Fosamax. You would probably want bone markers if you decide on those bisphosphonates that aren't as strong.
Finding a endocrinologist might start here. If you give us your city, their may be someone who will respond with a the name of their own doctor.
I've noticed that the younger endocrinologists offer you a choice. I look on the internet and try to find a doctor who does research or expresses interest in osteoporosis. If you find one with an osteoporosis specialty they are more likely to be apprised of the latest research, although the NASA researcher experience might weight against the idea.
Your trusted doctor was telling you what he genuinely thinks with regard to Prolia. Many doctors prescribe the drug. And there are patients who respond quite well to Prolia and take it for the rest of their lives. Initially the risks weren't known and the prevalence of those risk are either unreported of low.
It sounds as if you had no negative side effects with Prolia and have gained good bone density. I'm curious about why you've decided to quit, even as I applaud your decision.
Oddly, each of these medication is great for some, inefficient or devastating for others.
Had you any fractures while you were on Prolia?
It seems like it shouldn't be too difficult to find a endocrinologist who will work with you.
We'd like to help.
