Is an expired EpiPen better than no EpiPen at all? A recent study by pharmacist F. Lee Cantrell of the California Poison Control Center says definitely yes! After analyzing 40 expired EpiPens, he found that even 50 months past expiration the EpiPens retained 84 percent of epinephrine concentrations - enough to prevent anaphylactic shock. While Mylan is working on producing an EpiPen with a longer shelf life, patients are still encouraged to refill their EpiPen Auto-Injector approximately every 12 to 18 months to be assured of 100% effectiveness.

It's worth a shot to use an expired EpiPen, if that's all you have, a new study suggests.
For more than four years past their stamped expiration dates, the handheld injectors retained high-enough concentrations of epinephrine to in all likelihood prevent potentially fatal allergic reactions, the study found.
