How many days after Prolia injection should I wait before getting DEXA

Posted by pavi @pavi, Nov 15, 2024

I've been getting Prolia injections regularly for the last 2 years and am scheduled to get a DEXA scan. Is there a minimum number of days I should wait between my injection and getting the scan? I was diagnosed with early onset (premenopause) osteopenia and osteoporosis. Started treatment with Fosamax, bone density did not improve or stabilize, next step was Prolia.

Interested in more discussions like this? Go to the Osteoporosis & Bone Health Support Group.

@pavi Prolia won't effect the result of the DXA scan in any way. Unless you mean would you gain or lose bone a number of weeks or months after a Prolia injection. But the accuracy of a DXA would not change due to a Prolia shot.

@sequoia I really don't know. If someone were getting great results I'd guess a month or two. But then the result would be so small that you would still have margin of error concerns and you wouldn't know on the first scan if you could trust that an increase really was a gain. If you kept doing it then you could know whether to trust the early scans as you could see a trend. I cannot remember if I've ever seen studies where they took DXAs more often than 6 month intervals? Certainly by 6 months you could see where you were headed if you were getting good results. And if no gain you could probably surmise it was not working well for you.

I would think that 5 months after a Prolia injection might be the best timing for detection of effectiveness. If not working, then there would be time to switch medication before any rebound would set in.
