Cromolyn Sodium Concentrateon the FDA shortage list now

35months listed

Cromolyn Sodium Concentrate 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).
Cromolyn Sodium Concentrate has been listed 2 times since 2014: earlier listings lasted 1 year.
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.
