Pediatric Dose Calculator

Daily and per-dose amount from a mg/kg/day regimen

Child weight (kg)

Prescribed dose (mg/kg/day)

Number of divided doses per day (per day)

Equation & limitations

Equation: Daily total (mg/day) = dose (mg/kg/day) × weight (kg); per-dose = daily total ÷ doses/day
Version: Site-defined arithmetic from a prescribed mg/kg/day regimen
Source: Defined by Pharmapedia for this tool. NOT a substitute for a recognised paediatric dosing reference.
Appropriate in: Only where a prescriber has already specified a mg/kg/day value for this child.
Limitations: The per-dose figure assumes the daily total is divided into EQUAL doses — true only if the prescriber intends equal division.
No age-, indication-, or formulation-based checks; many paediatric drugs are dosed from body surface area or age bands.
Does not scale an adult dose; never dose a child from a scaled adult dose.
