Fewer But Longer Drug Shortages: USP Report
The United States Pharmacopoeia (USP) says the number of drug shortages declined in 2025, but those that did occur lasted longer. The USP 2025 Annual Drug Shortage Report says shortages begin and persist due mainly to four identified risk factors: low price, manufacturing complexity, geographic concentration of manufacturing, and quality concerns.
“Without targeted public and private sector action to improve supply chain resilience, drug shortages may be likely to persist or worsen, threatening patient access to essential medicines and undermining the stability of the U.S. medicine supply,” the report concludes.
USP notes that while the total number of shortages has declined year over year since 2023, the average duration of a drug shortage has grown to over five years. Simultaneously, it says, drug discontinuations have reached their highest level since 2019, with most discontinued products priced well below drugs in shortage, highlighting the economic pressures shaping the supply chain.
The report calls attention to 75 multi-year shortages, 44% of drugs in shortage having at least one key starting material (KSM) solely manufactured in a single country, six shortage drugs having all KSMs solely manufactured in a single country, a 60% increase in drug product discontinuations, and the fact that 26 drugs in shortage rely on China.
