Child Dose Calculator
Child Dose Calculator
Calculate accurate pediatric medication dosages from standard adult doses using three distinct clinical methodologies: Young's Rule, Clark's Rule, and Body Surface Area (BSA).
Patient Parameters
Clinical Precision & Methodology
Calculating pediatric dosages from adult prescriptions requires care. This tool implements three distinct formulas to provide a comprehensive dosing profile, with the Body Surface Area (BSA) method highlighted as the most clinically robust.
BSA / Mosteller Method
The Body Surface Area equation accurately scales physiological and metabolic processes. It is considered the gold standard for adjusting drug doses across different human sizes.
Clark's & Young's Rules
Includes Clark's Rule (based on patient weight relative to a 150lb adult) and Young's Rule (based on chronological age) for cross-referencing and historical compatibility.
Thermal Receipt Export
Generates a high-resolution, perfectly scaled PNG image designed specifically for 80mm thermal printers, enabling instant clinical handouts.
