What is the preferred route for epinephrine in anaphylaxis on a flight?

• A. Intravenous
• B. Intramuscular
• C. Subcutaneous
• D. Inhaled

Answer: (B)

In anaphylaxis, getting epinephrine into the bloodstream quickly and reliably is crucial. The intramuscular route— injected into the mid-outer thigh—provides rapid and consistent absorption and can be administered by trained bystanders using an auto-injector, which is especially important in the limited-care setting of a flight. Intravenous administration carries higher risk and requires close monitoring and IV access, so it’s typically reserved for hospital settings or controlled environments. Subcutaneous injections absorb more slowly and variably, delaying the needed effect. Inhaled epinephrine doesn’t treat a systemic anaphylactic reaction and is not appropriate for this situation.
