Meridian Medical Technologies expanded its voluntary recall of 13 lots of Mylan’s EpiPen and EpiPen Jr (epinephrine injection) Auto-Injector products used for emergency treatment of severe allergic reactions to now include additional lots distributed in the U.S. and other markets, according to an FDA alert.

The FDA reports that this recall is due to the potential that these devices may contain a defective part that may result in the devices’ failure to activate. The recalled product was manufactured by Meridian Medical Technologies and distributed by Mylan Specialty.

While the number of reported failures is small, EpiPen products that potentially contain a defective part are being recalled because of the potential for life-threatening risk if a severe allergic reaction goes untreated. Consumers should keep and use their current EpiPens if needed until they get a replacement. Consumers should contact Stericycle at 877-650-3494.

As stated on the product label, consumers should always seek emergency medical help right away after using their EpiPens, particularly if the device did not activate.

At this time, the 13 lots identified – distributed between Dec. 17, 2015, and July 1, 2016 – are the only EpiPen lots impacted by the US recall. Consumers who have EpiPens from lots that are not included in this recall, do not need to replace their EpiPen prior to its expiration date:
