Calculation Methodology

Total Daily Dose (mg) = Child Weight (kg) * Dose Rate (mg/kg/day). Single Dose (mg) = Total Daily Dose / Dosing Frequency. Liquid Volume (mL) = (Single Dose in mg * Concentration Volume in mL) / Active Drug Concentration (mg).

Frequently Asked Questions

Using the bottle strength (e.g. 100 mg per 5 mL): Multiply the required single dose in mg by 5, then divide by 100 to get exact volume in mL.
