Giving Your Child Acetaminophen Safely

ACETAMINOPHEN DOSAGES (Liquid, Chewable, Tablet)

It is best to give children acetaminophen using their weight instead of age when figuring out how much medicine to give. But if you don't know your child's weight, use their age to figure out the dose.

Acetaminophen is a pain reliever often used for kids (brand names include Tylenol® and others). It also helps bring down fevers. Acetaminophen comes in different forms, including:

  • liquid (also called a suspension)

  • chewable tablet

  • pill

  • suppository

When you give your child medicine, always check the strength listed on the label:

  • For a liquid medicine, strength means how many milligrams (mg) of medicine are in a certain amount of liquid (liquid medicines are measured in milliliters [mL]). For example: 

    • The liquid (suspension) label should say "160 mg per 5 mL."

  • For a tablet, pill, or suppository, strength means how many milligrams are in each. For example:

    • Chewable tablet labels should say "80 mg each" or "160 mg each."

    • Pill labels should say "325 mg each."

    • Suppository labels should say "80 mg each," "120 mg each," or "325 mg each."

  • Give medicine exactly as directed. Do not give medicine more often than is recommended, and do not give a larger dose than is recommended.

  • Do not give acetaminophen more than 5 times in 24 hours. Giving too much acetaminophen or giving it too often can cause problems with the liver.

  • Do not give any other medicines that also contain acetaminophen, such as cough, cold, or allergy medicines and some prescription pain medicines. Using two medicines that contain acetaminophen could cause your child to get too much.

  • Know your child's weight so that you can give the correct dose.

  • Make sure you and all caregivers write down the time that you give each dose of acetaminophen so that extra doses are not given by mistake.

  • You accidentally gave your child more than the recommended dose.

  • Your child is getting worse or not improving.
