@255anny,
I share your fears. These articles may be more reassuring than they should be.
Rcclast certainly stays in your body longer. It invades your bones and offers fracture prevention for years.
Prolia is completely gone after six months after which it provides no protection, but much greater risk of fracture if it isn't followed by an antiresorptive.
Some have extreme reactions to the drugs, but not everyone.

Amgen produces both Evenity and Prolia and there is big advertising encouraging doctors to use them in sequence.

You might have the labs done right away and see if they lead you in any direction. Have they ordered the bone markers CTX and P1NP. If not, you might request them.
You might pause until you have bone density results.
In every fine institution there are less than fine physicians, not to reflect on your new doctor, who may really be a new doctor.
"That does not sound right to me," is the most interesting part of your post. I agree.
I would have bone markers first to decide if I even want the next two Evenity injections.
I'd sooner see you on Reclast than Prolia. There is the windyshore's way of having a smaller dose of Reclast to determine any reaction you might have.
Mayo connect is a good source of information. Most of us have experienced those 3am readings. Stay with us, ask everything. Meanwhile be careful-- no lifting especially no lifting while twisting and no falling.
