Which route is used to administer epinephrine for anaphylaxis?

• A. Subcutaneously
• B. Orally
• C. Intramuscularly
• D. Intravenously

Answer: (A)

The main concept here is delivering epinephrine quickly and reliably to counteract the life-threatening effects of anaphylaxis. The best route is intramuscular injection, usually into the outer mid-thigh, because it provides the fastest and most consistent rise in epinephrine levels in an emergency. Subcutaneous administration often results in slower and more variable absorption, which can delay reversal of symptoms. Oral administration is ineffective in this setting due to poor and unpredictable absorption. Intravenous administration is reserved for hospital settings with close monitoring and carries higher risks, including potential severe cardiovascular side effects if not carefully titrated. So intramuscular delivery offers the quickest, most reliable effect for treating anaphylaxis.
