@gravity3 - I'm not sure what you are asking or at least why you are asking? Certainly stopping Prolia after 1 shot is safer than after 2 or 3 or a dozen in terms of avoiding the risk of "fracturing after Prolia".
But what are you thinking of doing after that 1 shot. You would still need to do something to hold onto Evenity gains. One shot would hopefully give you some bone density gain but you still have to follow up with something to hold onto those gains (from Evenity and Prolia).
The shortest time you have to wait to go back on Evenity is I think unproven at this point. There is that one study where they had a gap of a year in rounds of Evenity and Evenity worked just as well the second round. So a year gap worked fine it seemed. Please note though that gap was no med at all. The subjects lost all their first year gains and then gained that back again. So it looks like a year's gap will work. Could 6 months work or 8 months work? I have not seen any info on that?

What was your experience with Evenity, as far as side effects? Did you do anything before and after the injections to prevent possible side effects? You mentioned going back on Evenity, but I thought it was only recommended for one year? Thank you.
