What is the maximum single dose of Epi for pediatric use in allergic reactions?

In pediatric use for allergic reactions, the standard maximum single dose of epinephrine is 0.3 mg. This dosage is effective for treating severe allergic reactions such as anaphylaxis, as it helps to rapidly reverse symptoms by causing vasoconstriction, bronchodilation, and increased cardiac output.

Dosing guidelines often use weight-based calculations, where a common recommendation is 0.01 mg/kg up to a maximum of 0.3 mg. Because of this ceiling effect at 0.3 mg, it is determined that no matter the weight of the child, the maximum administration remains at this level to ensure safety and efficacy. In comparison, the other options either propose dosages that exceed recommended limits or do not align with established guidelines for emergency treatment in pediatrics.
