What is the maximum single-dose epinephrine for pediatric anaphylaxis?

• A. 0.05 mg
• B. 1.0 mg
• C. 2.0 mg
• D. 0.5 mg

Answer: (D)

Epinephrine is the first-line treatment for pediatric anaphylaxis, given intramuscularly at 1:1000 concentration. The dose is weight-based—0.01 mg per kilogram of body weight per dose—administered into the mid-thigh, and can be repeated every 5 to 15 minutes if symptoms persist. To balance efficacy with safety across a range of ages and weights, there is a practical ceiling per single dose, which is 0.5 mg. This means smaller children receive whatever 0.01 mg/kg calculates to (which will be well under 0.5 mg), while larger children may reach the 0.5 mg cap but should not exceed it in a single administration. Doses above 0.5 mg in one shot carry greater risk of adverse effects like tachycardia and hypertension. The other amounts listed are either too small to reliably halt anaphylaxis or exceed safe single-dose limits for a pediatric patient.
