When discontinuing Denosumab after more than 2-3 years of therapy, when do you recommend giving the first dose of zoledronic acid?

My practice has been that after 2-3 years of denosumab, I wait 6 months and then start zoledronic acid.

Six months after the last injection.

Yes, 6 months after last Prolia shot. I give 2 doses of Zoledronic 1 year apart and then consider drug holiday based on the DEXA report.
