When I had my one and only injection of Prolia in 2014 within days I had a rare side effect...my sense of taste was totally off. I could taste things but, it was distorted. Coffee was especially foul. I belatedly looked Prolia up and read all sorts of complaints by users, including the fact that it contained chemo. I went to my pharmacist who did the injection and asked but he basically hemmed and hawed. I just made up my mind I was never going to take it again. More recently, a poster on this website mentioned that possibility also.
I'm also probably biased. My husband , who had prostate cancer going into his bones, was treated with a denosumab infusion by his oncologist and died a few weeks later when he took a slight fall and broke his femur in 3 places. This may be why I'm associating denosumab with chemo.
So, do I know there is chemo in denosumab? No, but maybe a professional who monitors this website should give a definitive answer.
