Acetaminophen Dosage for Infants and Children

Children's medicines are specially formulated to deliver just the right amount of medicine to your little one. You should never give adult medicine to children. No matter the medicine or brand, always read and follow the label on the bottle before giving a dosage.

Only the dosing device provided with the product should be used to measure the proper amount of medicine.

Do not use more than one product containing acetaminophen at the same time. Ask your healthcare professional about dosages for children under 4 months of age.

For more information on administering children's medication, see our guide below or ask your family doctor or pediatrician.

If possible, use weight to dose, otherwise use age. Do not exceed more than five doses in 24 hours.
