What is the recommended action if someone shows signs of anaphylaxis?

The recommended action for someone showing signs of anaphylaxis is to administer epinephrine via an auto-injector. Anaphylaxis is a severe and potentially life-threatening allergic reaction that can cause symptoms such as difficulty breathing, swelling of the throat, hives, and a rapid heartbeat.

Epinephrine works by quickly reversing the symptoms of anaphylaxis, such as dilating the airways and increasing blood flow. It is critical to administer epinephrine as soon as possible, as this can significantly improve the chances of survival and reduce the severity of the reaction. After giving the epinephrine, it is important to seek emergency medical help immediately, as further medical intervention may be necessary.

The other actions are not appropriate responses to anaphylaxis. Providing food, encouraging water intake, or placing the person in a sitting position do not address the underlying issue of airway constriction and circulatory collapse that occurs during anaphylaxis and could potentially delay the essential treatment needed for this medical emergency.
