Methylphenidate (Ritalin and Concerta generics) has been on the FDA shortage list for 3 years and 3 months (August 2023 to October 2026).

  1. 102 of the 397 listings measured since 2014 lasted at least that long.
  2. Of the 102 past listings that reached the same age, 94% were still listed 6 months later (85 listings measured), 78% were still listed 12 months later (70 listings measured) and 62% were still listed 24 months later (51 listings measured).
  3. Methylphenidate (Ritalin and Concerta generics) has been listed 7 times since 2014: earlier listings lasted 5 months, 2 months, 1 year and 5 months, 1 month and 2 years and 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.
