Is there a generic of Calcitriol, and who makes it?
Calcitriol appears in 4 dosage-form groups in the FDA Orange Book as of 12 November 2026, with 10 generic makers listed as marketed across them. 1 group has a brand listed as marketed and no generic listed as marketed. The data does not state why, and it does not state that one is coming. Where both are dated, the first generic approval came between 4.7 and 16.3 years after the first brand approval. This is the Orange Book's listing, not a forecast.
