Thanks for your advice. I have had three Prolia injections and really dont want the next one. My bone density based on Dexa results definitely showed significant improvement. I am a big researcher. Reclast or Aclasta as it is called in Canada sounds like a whole new kettle of worms. However, discontinuing Prolia without going on a "relay" drug for one year puts you at risk for vertebral fractures. This is a tiny little fact that many doctors fail to mention at the outset. Amgen, the maker of Prolia, now has this warning in their own literature.
Right now, from my perspective, there are no terrific pharmaceutical choices for osteoporosis.
Wishing your parrot continued good health. Stay safe!
