Pediatric Dose Calculator
pediatric dose calculator. Get instant, accurate results. Enter values for instant results with step-by-step formulas.
Formula
Weight-based: Dose = Weight(kg) x mg/kg | Clark's Rule: (Weight lb / 150) x Adult Dose | Volume = Dose / Concentration
Weight-based dosing is the gold standard for pediatric dosing. Clark's rule approximates using weight. Young's rule uses age: (Age / Age+12) x Adult Dose. Always verify dose does not exceed adult dose.
Frequently Asked Questions
How do pediatric calculations differ from adult calculations?
Pediatric dosing is weight-based (mg/kg) or BSA-based (mg/m^2) because children are not small adults — they have different pharmacokinetics. Use actual body weight, check age-appropriate ranges, and never exceed adult maximum doses. The Young formula (age/(age+12) * adult dose) and Clark formula (weight/150 * adult dose) provide rough estimates only.
