Acetaminophen dosing for children
Acetaminophen is used to help:
- Reduce aches, pain, sore throat, and fever in children with a cold or the flu
- Relieve pain from a headache or toothache
Children's acetaminophen can be taken as liquid or chewable tablet.
If your child is under age 2 years, check with your health care provider before giving your child acetaminophen.
To give the correct dose, you will need to know your child's weight.
You also need to know how much acetaminophen is in the product you are using. You can read the label to find out.

- For liquids, the label will tell you how many mgs are found in 5 mL, such as 160 mg/5 mL.

Make sure you do not give your child more than one medicine that contains acetaminophen as an ingredient. For example, acetaminophen can be found in many cold remedies. Read the label before giving any medicine to children. You should not give medicine with more than one active ingredient to children under age 6 years.
When giving medicine to children, also be sure to follow important child medicine safety tips.
Be sure to post the number for the poison control center by your phone. If you think your child has taken too much medicine, call the poison control center at 1-800-222-1222. It is open 24 hours a day. Signs may include nausea, vomiting, tiredness, and abdominal pain.
Go to the nearest emergency room. Your child may need:
- To get activated charcoal. Charcoal stops the body from absorbing the medicine. It has to be given within an hour, and it does not work for every medicine.
- To be admitted to the hospital so they can be watched closely.
- Blood tests to see what the medicine is doing.
- To have their heart rate, breathing rate, and blood pressure monitored.
Contact your provider if:
- You are not sure about the dose of medicine to give your infant or child.
- You are having trouble getting your child to take medicine.
- Your child's symptoms do not go away when you would expect them to go away.
- Your child is an infant and has signs of illness, such as fever.
