Calculate pediatric drug doses using Young, Clark, or BSA-based rules.
Young's, Clark's and BSA-ratio rules are historical approximations, not a substitute for the drug-specific weight-based (mg/kg) dosing in a pediatric formulary. Never exceed the adult dose or maximum dose, and verify every dose with a pharmacist or prescriber. Not suitable for neonates.
No. Pediatric Dosing is free, with no signup required, and nothing you enter leaves your browser.
Pediatric Dosing is built on published formulas and reference ranges from established health sources. We revisit it periodically as guidance evolves; the "Last reviewed" date above shows when that last happened. If something looks wrong, tell us with the feedback button in the bottom-right corner.
No. Pediatric Dosing gives you a general estimate based on the inputs you provide, not a diagnosis. Existing conditions, medications, and individual history all change what a number actually means for you. Treat this as a starting point for a conversation with a doctor or other qualified health professional, not a substitute for one.
