pauladiamante, you'll be wise to take a follow-up medication after Evenity. And wiser still if you decline Prolia,
in my (not very) humble opinion. Without another medication you will lose any gain from Evenity within one year. Your doctor probably recommends Prolia because Amgen recommends that you stay on their medications.
Their reason is profit, but your doctor? I don't know. Could be the massive campaign directed toward doctors has affected his thinking.
I'd wait for the dexa results and ask for a CTX and P1NP. I'd be trying to get a earlier dexa if I'd completed 6 months from the injection.
Prolia would take your CTX down to around 50, which has a good and a bad story to tell.
CTX stands in as a measurement for osteoclasts Osteoclasts break down damaged bone. Prolia builds bone over bone that is breaking down. It collects the fissured bones and the unformed osteoclasts. Because it collects less stable bone, you have a risk of fractur and/or decay in that bone. Because it collects the osteoblasts, if you ever stop the drug you are likely to experience multiple fractures, (cascades they call them), unless you take a strong medication to block and destroy those osteoclasts.
You'll field differing opinions, so listen carefully, and question everything.
