In the case of an allergic reaction where the person has an Epinephrine pen, what is the priority action?

In the case of an allergic reaction where the person has an Epinephrine pen, the priority action is to administer the epinephrine as soon as possible. An anaphylactic reaction can escalate quickly, leading to life-threatening symptoms such as difficulty breathing or loss of consciousness. The prompt use of an epinephrine pen can significantly reduce these risks by constricting blood vessels and opening airways, thus stabilizing the person's condition.

Once the epinephrine is administered, it is crucial to seek additional medical assistance immediately, either by calling emergency services or having someone else do so. This approach emphasizes the importance of immediate care for the individual suffering the allergic reaction, rather than delaying action in favor of calling for help first.
