@mayblin Hi there.
I have no idea if Medicare will cover a second round of Evenity. There are several factors involved. One being what will my next DXA show. Will Risedronate have kept my Evenity gains or even improved my scores, or will I have lost some of my gains? I went from a worst of -4.1 in my spine to a worst of -2.1 with round one of Evenity. My only score in the osteoporosis range after Evenity was a -2.5 in my femoral neck. Will Medicare see that as bad enough to cover Evenity? Will Medicare even cover Evenity twice - I just don't know.

Also, my wife and I have moved across country so I have to get a new doctor probably. Though perhaps it could go thru the doctor I've been using for years but administer it myself? So many complications.

As to CTX levels. My CTX seems to go up rapidly just several weeks after my monthly Risedronate pill. After I observed this I took the monthly Risedronate every two weeks for a bit and now I'm varying it between 3 weeks and a month. That last part is not due to strategy but the unsettledness of my life after fleeing the California fires and trying to settle in a new place.
It looks like my CTX levels will rise about 200 pts between 2 weeks after the Risedronate to 4 weeks after. Like from 190 to 390 for example.
So looking at that, I think I could take Evenity one to two months after the last Risedronate? Any time I get up around 400 I guess. I will also ask my doctor what he thinks.
Thanks for asking as I've got to get moving on all this.
