Common Questions About Epinephrine EpiPen Safety

UNSAFE

Is it safe to use epinephrine epipen after the expiration date?

Expired epinephrine epipen may have reduced potency and effectiveness. The FDA does not recommend using medications past their expiration date, as the chemical composition may change over time. Some medications can become less effective or potentially harmful. Consult a pharmacist before using any expired medication.

CAUTION

What if epinephrine epipen looks different than when purchased?

Changes in color, consistency, or separation in epinephrine epipen typically indicate the product has degraded. While this may not pose a safety hazard for non-food items, it usually means reduced effectiveness. If the product has solidified, separated significantly, or changed color dramatically, it is best to replace it.
