What is the most important medication to give for anaphylactic shock?

• A. IV epinephrine
• B. Antihistamines
• C. Albuterol
• D. IM epinephrine

Answer: (D)

Epinephrine is the first and most critical treatment for anaphylaxis because it rapidly reverses airway edema, bronchoconstriction, and hypotension. The intramuscular route is preferred because it delivers a fast, reliable dose with a favorable safety profile and is easy to administer in most settings (often into the mid-outer thigh, using an auto‑injector). Typical adult dosing is 0.3–0.5 mg of 1:1000 epinephrine, repeated every 5–15 minutes as needed while monitoring the patient; children are dosed by weight. Intravenous epinephrine is reserved for severe, refractory shock in a monitored setting due to higher risk of complications. Antihistamines and bronchodilators can help with certain symptoms but do not promptly treat the life-threatening manifestations. So, the most important initial medication is intramuscular epinephrine.
