I was on Prolia for osteoporosis for about six years without incident. It was helping somewhat in slowing bone loss. However an change in doctors at my medical center resulted in a delay in receiving a shot. No one warned me to come in for my shot even though I was "between doctors," and a few weeks later I experienced three vertebral compression fractures. My new doctor and I have filed reports with the FDA about this. I have spoken with Amgen, Prolia's manufacturer, about this. However, nowhere in Amgen's literature (especially for patients) can I find the word "delay." I would like to see BOXED WARNINGS about the dangers of even short delay in Amgen's labeling for Prolia for doctors and in their instructions for patients. Despite physical therapy etc. I do not know when I will be out of disabling pain. It is clear that the Amgen is not about to do this very soon if at all so I want to warn others.

This is my second response to address the delay getting a Prolia shot. My doctors told me there is a "window" and one can have as much as a month delay without concern. I myself recently had a 3 week delay with no problem.
Thank you for your response! I'm really glad you are OK. What I'm learning is that this is a variable and the docs think I am clear this faster than average.
To add to previous response, the fractures probably occurred around 4 weeks after my Prolia shot was due, They were not positively diagnosed with MRI until I'd been in terrible pain for about two weeks -- at first I just thought I'd badly strained my back. The doc said this was on the short side of the spectrum and that she was presenting my case at a medical conference. So while it may have been on the short side, it happened, it happened to me, and it basically destroyed my active life.
