Dosing charts for infant Tylenol can be found on several websites, including Ask Dr. Sears, St. Louis Children's Hospital and Parents. The appropriate dose of Tylenol is based on the child's weight in pounds. It is important to ensure the medication's concentration matches what is on the chart, states Parents.
Using the syringe or dropper that came with the medication is the best way to measure a dose, according to St. Louis Children's Hospital. If a syringe or dropper is not available, a measuring spoon may be used. Regular kitchen spoons are not a reliable method for measuring medications. Tylenol may be given every four to six hours, not to exceed five doses in 24 hours.
