Riluzole has been on the FDA shortage list for 2 years and 9 months (February 2024 to October 2026).
- 123 of the 397 listings measured since 2014 lasted at least that long.
- Of the 123 past listings that reached the same age, 88% were still listed 6 months later (102 listings measured), 83% were still listed 12 months later (85 listings measured) and 60% were still listed 24 months later (58 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.
