FDA Extends Shelf Life of Four Lots of Paxlovid to 12 Months

The FDA has extended the shelf life of four lots of Pfizer’s COVID-19 drug Paxlovid (nirmatrelvir, ritonavir) from nine months to 12 months.

The extension affects lots with expiration dates either on July 31 or August 31 that were labeled with a nine-month shelf life before the drug received Emergency Use Authorization (EUA) from the agency. The December 2021 EUA established a 12-month shelf life for all Paxlovid lots.

The EUA for Paxlovid is for treatment of mild-to-moderate COVID-19 adult and pediatric patients 12 years and older who weigh at least 88 pounds.
