How It Works

Pediatric dosing requires careful weight-based calculation because children metabolize drugs differently than adults. The calculated dose (mg/kg x weight) must always be checked against the maximum recommended single dose. Body surface area (BSA) using the Mosteller formula can provide an alternative dosing method for certain medications like chemotherapy agents.
