Change drs at once. Evenity is also made by AMGEN who make Prolia. How convenient to have another of their drugs available. And these guys are working for AMGEN. Well done finding that out. We all in the same boat and feel depressed that we have been advised to take drugs that hasn't had long term data. I read that some women have had increased bone density with Prolia. What a joke as l believe those new 'bones' are mere camouflage jobs. I read thar it's like renovating a house, where you cover up the problem but it is still poorly maintained underneath. Same with Prolia bones. That's why you are lucky if you can get an Echolight scan that shows you the quality of the bones. Good luck to all of us.
