The number of prescription drug shortages in the U.S. fell by 23% last year, marking the second consecutive year of declines and the lowest level since 2017, according to a new analysis that otherwise found troubling signs about medicines that are in short supply.
For instance, the average drug shortage lasted 5.3 years, exceeding the 4.3 years seen in 2024 and greatly outpacing the average two-year shortage experienced in 2019. Moreover, nearly two-thirds of out-of-stock medicines were in short supply for more than three years, and 39% were unavailable for more than five years.
Meanwhile, the 75 drugs that were in short supply last year spanned 130 therapeutic categories, indicating that shortages affected a wide range of diseases and patient populations, according to the analysis by U.S. Pharmacopeia, an independent organization that develops standards for medicines.
