@babbsjoy you might want to see an endocrinologist who specializes in osteoporosis. My doctors (two) don't prescribe Prolia unless they have to, due to the rebound. I don't think you can take Prolia the rest of your life unless you are much older! Studies I have seen are on 3,4 and 8 years. One person on another forum is taking it for 5. Then you do Reclast.

Keith McCormick, in his book "Great Bones", and on his videos, suggests doing just 1-3 shots of Prolia if you do take it, then Reclast (or Fosamax, but Reclast is stronger against rebound).

I did Tymlos, then Evenity (4 months only, had side effects) and now Reclast. I was the only patient in my doctors' practices (both of them) doing Evenity after Tymlos but I think that will be more common- and others on the forum have done that.

My docs say people need to be very very careful about stopping Prolia. And though you can take it longer than other meds, it is an anti-resorptive and over time the risks of jaw necrosis and atypical femur fracture go up.

A lot of people do Reclast after Tymlos. Hope you can start on a good med!
