Frequently Asked Questions

How is pediatric dosage calculated?

How it works

Standard pediatric dosing is calculated using the weight-based formula:Weight (kg) × Dose (mg/kg). The result is then compared against the maximum adult safe dose to prevent toxicity.

// Logic

dose_mg = weight_kg * dose_per_kg;

final_mg = Math.min(dose_mg, max_dose);

volume_ml = (final_mg * conc_ml) / conc_mg;
