What is the maximum single dose of epinephrine (1:1000) for pediatric anaphylaxis per administration?

• A. 0.3 mg
• B. 0.1 mg
• C. 0.5 mg
• D. 0.05 mg

Answer: (A)

Dosing epinephrine for pediatric anaphylaxis is weight-based with a safety cap per dose. The standard is 0.01 mg/kg given intramuscularly, but you do not exceed 0.3 mg in a single administration. Because epinephrine 1:1000 is 1 mg per mL, 0.3 mg corresponds to 0.3 mL. So a child weighing up to about 30 kg could receive up to 0.3 mg per dose (lower doses for lighter children, e.g., 0.15 mg at 15 kg, 0.25 mg at 25 kg). If a heavier child needed more, you would still limit each dose to 0.3 mg and monitor the response, repeating if necessary per clinical judgment. The cap helps prevent excessive adrenergic effects like severe tachycardia, hypertension, and arrhythmias while still delivering a life-saving dose for airway and circulation compromise.
