What is the initial treatment for suspected anaphylaxis?

• A. Oxygen therapy
• B. Epinephrine auto-injector
• C. Remove allergen
• D. Place patient in Trendelenburg

Answer: (B)

Prompt epinephrine administration is the most important initial step in suspected anaphylaxis. Epinephrine acts quickly to reverse the life-threatening features by constricting blood vessels, reducing airway swelling, and dilating the airways, which helps restore breathing and blood pressure. The preferred route in the field is intramuscular injection into the mid-outer thigh, using an epinephrine auto-injector when available, and repeating per protocol if symptoms persist. After giving epinephrine, activate advanced care, monitor the airway, breathing, and circulation, and provide high-flow oxygen if needed. Removing the allergen and supportive measures are important, but they do not address the immediate life-threatening pathophysiology as directly as epinephrine. Trendelenburg positioning is not recommended, as it can hinder breathing and does not treat the underlying problem.
