What is an appropriate initial emergency treatment for anaphylaxis?

• A. Call 911 and administer epinephrine immediately.
• B. Administer only oral antihistamines and rest.
• C. Wait and monitor without intervention.
• D. Administer aspirin.

Answer: (A)

Anaphylaxis requires rapid reversal of airway edema, bronchoconstriction, and circulatory collapse, and the first-line treatment is epinephrine given as soon as the reaction is suspected. Epinephrine acts quickly by constricting blood vessels to raise blood pressure and reduce swelling, while also relaxing bronchial smooth muscle to improve breathing and limiting further mediator release. This immediate intervention buys crucial time for the person to be evaluated and supported by emergency responders. Calling emergency services is essential because further treatment and monitoring are needed, and the person may need additional doses or advanced care after the initial epinephrine. While antihistamines and other meds can help with itching or hives, they do not treat the life-threatening aspects of anaphylaxis and are not a substitute for epinephrine. Waiting or delaying treatment increases the risk of severe airway obstruction, cardiovascular collapse, and death. Aspirin has no role in treating anaphylaxis and could worsen the situation. If available, administer epinephrine intramuscularly in the mid-outer thigh right away, and seek emergency help. If symptoms recur or persist after 5–15 minutes, a second dose may be given (under guidance). Keep the person calm and still, monitor breathing, and provide oxygen or other supportive care as advised by responders.
