Both Reclast and Prolia can help your bones while taking an AI. Both of them have an added benefit of prevention of metastasis to bones. Apparently, they are given to patients with bone cancer, also. Prolia is a quick injection every 6 months and Reclast is an infusion once a year but I don’t remember how long it takes. Talk to your oncologist. My endocrinologist and my oncologist kept in touch. I was thrown into osteoporosis because I did not take Prolia during the first 6 months of the AI. The doctors wanted to see if I had side effects from the AI first. Those 6 months without apparently had an impact made. Once I started, my bone density improved—no osteoporosis. I was given a last Prolia this summer at my 5 year anniversary. But I will have to start on something else in January because I was informed that if I don’t maintain what I recovered, I could very quickly lose all the benefits. My endocrinologist said my goal is to maintain bone, not build bone at this point. (This effect has a name but I don’t remember). I could have asked for a year of Reclast. I am not sure what I will decide since the other meds also can have some side effects. Still researching all the options.
