I was on Prolia without any issues for several years until time for my December injection. I had it scheduled and my appointment was canceled. When I called about that, I was told by my doctor’s office that my insurance carrier made the change. After I did my research and spoke with my. Rheumatologist I decided to go with the Reclast. The infusion was no problem and the fact Medicare paid sure made it easier on my budget. However, if you are told you might have some flu-like side effects, I suggest you prepare by hydrating and get some nsaids or Tylenol in your system first. I’ve never had a worse reaction. Wasn’t able to get out of bed the next day. Headache from hell. The good news is I’ll only need one more, most likely!
