Pain Home > Children's Acetaminophen Dosage

Children's acetaminophen dosage recommendations will vary for each child depending on his or her age and weight. If you accurately know your child's weight, it is best to base the dosing on weight, rather than age. A children's acetaminophen dose can be given every four hours, but you should not give your child more than five doses in a 24-hour period.

Children's Acetaminophen Dosage: An Introduction

The recommended dose of children's acetaminophen (Children's Tylenol®) will vary depending on a number of factors, including:
  • Your child's age and weight
  • Other medications your child may be taking
  • Other medical conditions your child may have.
As is always the case, do not adjust the dose of children's acetaminophen unless your child's healthcare provider specifically instructs you to do so.
