I had 2 Reclast infusions when I was 53 and 54. I made gains but quit taking it because of an insurance change. Fast forward 10 years and my spine bone density results came back -4.5. I took Reclast for 2 more years and my spine bone density improved to -4.1. Since most of that gain came the first year, my doctor put me on Prolia. After one year of Prolia, my spine improved to -3.6. I just had my third Prolia shot. I am fortunate to not have side effects. I will probably be on Prolia the rest of my life. The point is, most of us with osteoporosis will be on a bone drug the rest of our lives. Reclast was only temporary the first time I took it.
