@pedsnurse61 if you do Prolia you will eventually do Reclast or another bisphosphonate anyway because you cannot just stop Prolia without quickly losing what you gained.

In his new book "Great Bones," Dr, Keith McCormick explains that Reclast stays in the system much longer than Prolia, with a very long half life of 10 years, so you can safely take a break from meds once your gains have been "locked in."

You can do Prolia for a few years, but you also, according to the same book, have to be careful about the timing of the switch to Reclast from Prolia. If too soon, the Reclast won't work and if too late, the rebound effect of stopping Prolia could already kick in. He suggests doing CTX tests to determine timing.
