broken13: It's actually not a generic, but rather called a biosimilar. But still, semantics don't really matter; it's a copy-cat drug of Prolia. And after 5 successful years on Prolia I got really sick on this copy-cat drug, (called Jubbonti) after being injected with it last month. It's only been on the market for 3 months. The company that has marketed Jubbonti seems to specialize in marketing biosimilars and generics after the patents for the original drugs expire. I am hoping to get an exception approved to only receive Prolia injections, again, in the future. I am glad to hear your sister has been on Prolia twice as long as I have and is doing well with no side effects. Thank you for posting.
