Anaphylaxis requires rapid reversal of the allergic response, with attention to airway, breathing, and circulation. The most important step is administering epinephrine promptly by the intramuscular route, which quickly reduces airway edema, relaxes bronchospasm, and improves blood pressure. This treatment choice directly addresses the life-threatening aspects of the reaction and often buys time for additional care. After giving epinephrine, focus on maintaining a clear airway, providing oxygen, and supporting circulation, while closely monitoring the patient.

Observing without treatment misses the urgent need to reverse the reaction. Starting antibiotics has no role in the initial management of anaphylaxis unless there is another infection present. Intubation is only necessary if there is a true, current airway compromise, not in every case. Adjuncts like antihistamines or steroids can be used later, but they do not replace the need for timely epinephrine.
