Safe Acetaminophen Dosing for Infants and Children

This guide will help you give your child the right amount of medicine to help them feel better, faster. When possible, use your child’s weight to find the right dose. If not, use age to determine the right amount. Never give your child more than 5 doses in 24 hours and ask your family doctor or pediatrician which product is right for your child.

Improved Dosing Accuracy:

  • The makers of TYLENOL® recently introduced a new, enhanced bottle design on infants’ liquid suspension products. These enhancements include a protective flow restrictor in the opening and a SIMPLEMEASURE® Push-In-Syringe, which will provide caregivers with the following important benefits:
    • Better dosing accuracy and ease of administration;
    • Better control when dispensing the medicine and reduced spillage;
    • Further reduced risk of children being able to get the medicine in the bottle.
  • The protective flow restrictor and specially designed dosing cup has also been introduced on our Children’s TYLENOL® Liquid Products.
