What to do if an EpiPen malfunctions in an emergency?

April 5, 2026

Quick Answer

SHOULD_NOT_RELY_ON_A_MALFUNCTIONING_EPIPEN: If an EpiPen malfunctions, administer manual chest compressions and rescue breaths if necessary, and call emergency services immediately for further assistance. If multiple EpiPens are available, try another device if the first one does not work.

Understanding EpiPen Malfunction

EpiPen malfunctions can occur due to various reasons, including the device’s expiration date, incorrect usage, or the inability to penetrate the skin. If you suspect an EpiPen malfunction, do not delay seeking medical help.

Alternative Procedures

When an EpiPen malfunctions, the American Heart Association recommends performing manual chest compressions and rescue breaths according to the 30:2 ratio. This involves 30 chest compressions followed by two rescue breaths. If the patient is unresponsive, not breathing, or not breathing normally, initiate CPR immediately. Use a defibrillator if available.

Emergency Response

In the event of an EpiPen malfunction, call the emergency services number in your area (such as 911 in the US) and provide as much information as possible about the situation. Do not attempt to revive the patient alone, as this can lead to further complications. Stay with the patient and provide assistance until medical professionals arrive.
