The FDA has extended the expiration date on certain lots of EpiPens in response to the current shortage. The indicated lots have been deemed safe for an additional four months, according to the FDA, who reviewed data provided by Mylan prior to their decision. They hope this will help to mitigate the shortage during back-to-school season. Even with this change, there are alternative epinephrine autoinjectors available such as Adrenaclick and Auvi-Q.
If you have an EpiPen please see the link below to see if this extended expiration date applies to you:
