What is the recommended EMS treatment for anaphylaxis from an insect sting?

• A. Administer epinephrine promptly per protocol
• B. Administer antihistamines only
• C. Transport without treatment
• D. Observe and reassess without epinephrine

Answer: (A)

Anaphylaxis is a life-threatening emergency where airway, breathing, and circulation can fail rapidly, so the most crucial EMS step is to administer epinephrine promptly. Epinephrine works quickly to constrict blood vessels, reduce swelling, open the airways, and improve circulation, addressing the key threats in an insect-sting reaction. Giving it as soon as anaphylaxis is suspected, according to your protocol, maximizes the chance of reversing the reaction. If symptoms persist or recur, repeat doses as allowed by your protocol, and then ensure transport with continuous monitoring.

Antihistamines, while they can help with itching or hives, do not reverse airway swelling, bronchospasm, or shock, so they’re not appropriate as the sole treatment for anaphylaxis. Transporting without treatment delays a life-saving intervention. Observing without epinephrine leaves the dangerous reaction untreated and can lead to rapid deterioration.
