What is the proper first aid action for anaphylaxis?

• A. Give them antihistamines and rest.
• B. Call for help only after symptoms worsen.
• C. Check breathing and monitor.
• D. Epi-pen injection and monitor closely.

Answer: (D)

Anaphylaxis is a life-threatening reaction that can progress rapidly, so the most important action is to deliver fast-acting treatment and get professional help right away. Administering an epinephrine auto-injector (EpiPen) quickly is essential because epinephrine rapidly opens the airway, reduces swelling, and helps stabilize blood pressure. After giving the injection, call emergency services and monitor the person closely, watching for any return of symptoms or the need for a second dose.

Antihistamines and resting won’t reverse the dangerous airway swelling or shock that can occur with anaphylaxis, so they are not sufficient as the primary treatment. Simply checking breathing and monitoring without providing the epinephrine step delays life-saving action, which is why the best approach is to administer the EpiPen and then monitor while help is on the way.
