Hydroxocobalamin has been on the FDA shortage list for 2 years and 6 months (May 2024 to October 2026).
- 143 of the 397 listings measured since 2014 lasted at least that long.
- Of the 143 past listings that reached the same age, 79% were still listed 6 months later (111 listings measured), 73% were still listed 12 months later (92 listings measured) and 57% were still listed 24 months later (63 listings measured).
- Hydroxocobalamin has been listed 2 times since 2014: earlier listings lasted 9 months.
- 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.
