Acetaminophen dosage for children

Published on March 8, 2024 at 8:00 / Updated on March 26, 2024 at 8:00

Acetaminophen (e.g., Tylenol, Tempra) is a drug that is used to treat fever and pain. Below is a dosage chart for children. It is better to use the child's weight instead of age, and to use a dosing device rather than a spoon. Be careful, there are several products with different acetaminophen concentrations.

To determine the right dosage for your child, follow these steps:

  • Find the line that corresponds to the child's weight (in pounds or kilograms).
  • Identify the proper dose based on the product you have in hand.
  • Administer the dose every 4 to 6 hours for a maximum of 5 doses within a 24-hour period.
