The Food and Drug Administration (FDA) has extended the expiration date of certain lots of Mylan‘s EpiPen (epinephrine) Auto-Injector 0.3mg by 4 months past the labeled date. 

This date modification beyond the approved 20-month shelf life was based on an FDA review of product stability data submitted by Mylan. Several factors contributed to the product’s limited availability in certain areas of the US, including regional supply disruptions and manufacturer issues. Specifically, Mylan cited intermittent supply constraints due to manufacturing delays from their partner, Meridian Medical Technologies, a subsidiary of Pfizer. Continual supply from Meridian is still ongoing and Mylan is expediting shipment to wholesalers upon receipt. Meridian also manufactures EpiPen Jr 0.15mg Auto-Injectors and the authorized generic versions of these strengths.

“We’ve completed the necessary reviews of the data to extend the expiration date by four months for specific lots of EpiPen that are expired or close to expiring. We’re hopeful this action will ensure patients have access to this important medication and provide additional peace-of-mind to parents as the agency works with the manufacturer to increase supply,” said Janet Woodcock, MD, director of the FDA’s Center for Drug Evaluation and Research.
