Which items are typically included in onboard kits to treat allergic reactions?

• A. Oxygen cylinder and tourniquet
• B. Epinephrine auto-injector and antihistamines
• C. Antibiotics and IV fluids
• D. Pain relievers only

Answer: (B)

When thinking about treating allergic reactions on board, the priority is to quickly reverse potential anaphylaxis and relieve symptoms. Epinephrine auto-injector is the essential first-line treatment because it rapidly narrows blood vessels, relaxes airway muscles, and reduces swelling, which can stop a life-threatening reaction in its tracks. Antihistamines then help relieve symptoms caused by histamine, such as itching, hives, and sneezing, acting as a useful adjunct but not a substitute for epinephrine in a severe reaction. The other options don’t fit because they don’t provide the targeted, immediate action needed for allergic emergencies. An oxygen cylinder and tourniquet aren’t specific allergy treatments—oxygen is supportive if breathing is compromised, and a tourniquet is used for bleeding, not allergic reactions. Antibiotics and IV fluids aren’t appropriate as a routine treatment for allergies; antibiotics don’t address the allergic mechanism, and IV fluids are reserved for specific severe reactions and medical guidance. Pain relievers only address discomfort and don’t treat the underlying reaction. So, the best combination for onboard allergic reactions is an epinephrine auto-injector for quick reversal of severe symptoms, with antihistamines to help manage milder histamine-related symptoms.
