What action should be taken if a person is experiencing an allergic reaction to wasp stings and is unable to remember how to use their EpiPen?

Administering an injection of epinephrine using the autoinjector is the appropriate action to take for someone experiencing a severe allergic reaction, also known as anaphylaxis, due to wasp stings. When a person is having such a reaction, their symptoms can escalate rapidly, and it is critical to act quickly to provide relief. An EpiPen, which contains a dose of epinephrine, works to constrict blood vessels, thereby increasing blood pressure, and relaxes airway muscles, which helps improve breathing.

In the case presented, if the person is unable to remember how to use their EpiPen, the best response is to confidently administer the injection, following the general guidelines for use. Waiting for emergency medical services without providing epinephrine could lead to a worsening of the individual’s condition, particularly if their airway starts to swell or if they experience shock. It's essential to emphasize that the benefits of administering epinephrine in an allergic emergency far outweigh the risks associated with its use, especially when the alternative could be life-threatening.
