Let me throw in my two cents worth on Prolia. I was diagnosed with breast cancer 2-1/2 years ago. After surgery and radiation I was put on Arimidex to hopefully prevent a recurrence of my hormone receptive positive breast cancer. Because this drug depletes calcium in the body, and the fact that I was already showing signs of osteoporosis, I was also put on Prolia. I have had five shots. I recently discontinued taking the Arimidex because of the side effects and therefore my oncologist decided I no longer need any more Prolia shots. It’s hard for me to say which side effects came from the Arimidex and which came from the Prolia, but I definitely experienced a wide range of side effects. I’m all for doing whatever it takes to stay alive and healthy but, my experience with these two drugs detracted far too much from my current quality of life. I realize I’m not going to live forever and I want the best possible day every day that I am alive. For the record, my side effects included weight gain, joint pain, joint weakness, an occasional weird rash, digestive issues (don’t ask), insomnia, hair thinning, mood swings, leg cramps, swelling in feet and hands (had to get my rings sized and buy a size larger shoe), hot Flashes/Cold Sweats. . . (Maybe a few others that escape me now). I think you can see why I chose to discontinue use. My surgeon and my oncologist have been very supportive of this decision.
