Promethazine Hydrochloride has been on the FDA shortage list for 2 years and 11 months (December 2023 to October 2026).
- 115 of the 397 listings measured since 2014 lasted at least that long.
- Of the 115 past listings that reached the same age, 88% were still listed 6 months later (93 listings measured), 83% were still listed 12 months later (79 listings measured) and 62% were still listed 24 months later (52 listings measured).
- None of this predicts an end date. A listing ends when the FDA removes it, which reflects supply across the whole country, and says nothing about one pharmacy's shelf.
