## Methodology and attribution

KinToolkit organizes the selected US liquid medicine labels into bottle-matching tools and reference tables. The calculator and these tables use the same range lookup, not a continuous weight formula. Manufacturer labels are the primary sources; this summary does not establish an independently validated or clinically reviewed dosing protocol.

## Before using label directions

Verify the active ingredient, concentration and warnings on your own package. KinToolkit is an independent educational tool, not a medical professional or a substitute for your child’s clinician. The brands mentioned above are not affiliated with KinToolkit.
