Common questions

Which pediatric dosing rule is most accurate?

Body-surface-area methods like the Mosteller BSA rule are generally considered the most reliable. Weight and age rules like Clark's and Young's are older approximations.

Can I use these rules to dose my child's medicine?

No. These historical rules are educational only. Always follow the label or a clinician's instructions for actual dosing.
