Patients with anaphylaxis should first have a patent airway. What medications are involved in treatment?

• A. Epinephrine; steroids to prevent late-phase reactions, and H1/H2 blockers i.e. Benadryl and Ranitidine
• B. Bronchodilators and diuretics
• C. Antibiotics only
• D. Epinephrine only

Answer: (A)

In acute anaphylaxis the top priority is reversing airway compromise and shock with a medicine that acts quickly on the multiple pathways causing symptoms. Epinephrine is the cornerstone because it rapidly constricts swollen blood vessels (alpha-1 effect) reducing airway edema and improving blood pressure, while also relaxing airway smooth muscle (beta-2 effect) to relieve bronchospasm and supporting heart function (beta-1 effect). This single drug addresses the most dangerous immediate threats. Adding corticosteroids helps reduce late-phase and biphasic reactions, which can occur after the initial event, even though their effects aren’t immediate. Histamine-driven symptoms are further mitigated by H1 and H2 antihistamines, which serve as helpful adjuncts to control itching, hives, and other histamine-mediated signs, though they don’t replace epinephrine in treating the crisis. Other options don’t fit the emergency needs: diuretics don’t treat the acute vasodilation and airway swelling, and antibiotics aren’t useful unless there’s an infection driving another issue. Bronchodilators may help with bronchospasm as a separate measure, but without epinephrine they won’t reverse the critical airway and blood pressure problems. So the best answer combines epinephrine with steroids and H1/H2 blockers as adjuncts to comprehensively address the immediate crisis and prevent later reactions.
