If anaphylaxis symptoms persist after initial epinephrine, what should you do?

When anaphylaxis continues after the first epinephrine dose, you repeat epinephrine rather than stopping treatment. The initial dose often helps, but mediator effects can persist or rebound, so a second dose is given to reinforce the needed vasoconstriction and bronchodilation. In practice, give another IM epinephrine dose after about 5 to 15 minutes if symptoms—such as airway compromise, hypotension, or bronchospasm—remain. The standard approach is adults 0.3–0.5 mg; children 0.01 mg/kg (up to 0.3 mg) per dose, administered in the same mid-thigh injection site. After that, continue with airway support, oxygen, IV fluids, and close monitoring. Antihistamines and steroids are adjuncts with slower onset and do not replace the need for another epinephrine dose, and stopping epinephrine would be unsafe.
