Hydroxocobalamin has been on the FDA shortage list for 2 years and 6 months (May 2024 to October 2026).

  1. 143 of the 397 listings measured since 2014 lasted at least that long.
  2. 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).
  3. Hydroxocobalamin has been listed 2 times since 2014: earlier listings lasted 9 months.
  4. 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.
