Dosing Chart

The American Academy of Pediatrics (AAP) recommends that all pediatric medication dosing be done in milliliters (ml) and not teaspoons to avoid dosing errors. Syringes, droppers, and medicine cups are the most accurate dispensing devices and are available at local pharmacies.

The following chart is based on your child’s weight, and not age.
