Whenever our kids have a fever or aches, we give them the ‘harmless’ acetaminophen. And it provides relief from the pain almost immediately.

But after a few hours, the fever/ pain comes back, and we give one more dose. We are happy that the child’s suffering has come down but what if unknowingly overdose them?

MomJunction tells you about the right dosages of acetaminophen (Tylenol) for kids, the side-effects of an overdose and more about the drug.

What Is Tylenol Or Acetaminophen?

Tylenol is the trade name for the generic drug ingredient acetaminophen, also known as paracetamol. Acetaminophen works as an analgesic or pain reliever, and antipyretic or fever reducer (1). It is manufactured under several brand names Tylenol, Feverall, Anacin, and Pediapap. The drug is available in different forms such as tablets, chewable tablets, capsules, liquid or solution, long-acting or extended-release tablet, dissolving tablets or melt away.

Acetaminophen is prescribed to children to relieve the symptoms of a cold and mild-to-moderate pain, including:

  • A headache
  • Fever
  • A sore throat
  • Muscle ache
  • A toothache
  • Back pain

Though it provides relief from multiple common ailments in children, you need to give the drug in the right dosages.

Tylenol Dosage For Kids

This Tylenol dosage chart will help you avoid overdosing.

Dosage based on a concentration of 160mg in 5mL (less concentrated) (2)

Age Weight Dose
2 to 3 years24 – 35lb (11 – 15.9kg)5mL (160mg)
4 to 5 years36 – 47lb (16 – 21.9kg)7.5mL (240mg)
6 to 8 years48 – 59lb (22 – 26.9kg)10mL (320mg)
9 to 10 years60 – 71lb (27 – 31.9kg)12.5mL (400mg)
11 years72 – 95lb (32 – 43.9kg)15mL (480mg)

160mg per 5mL is less concentrated liquid acetaminophen, and 80mg per 1mL is more concentrated liquid (3).

Confusions are likely to arise from the dosage instructions or Tylenol concentrations. Therefore, if the doctor prescribes a 5mL dose of the less concentrated liquid, but you administer a 5mL dose of the more concentrated liquid, then it could lead to an overdose.

  1. Do not switch devices used for dosing between different products.

Frequently Asked Questions

1. What to do if I missed a dose?

If you have missed one dose of Tylenol for your child, give it to them when you remember. However, if the time for the next dose is close, wait for the right time and give the next dose. Do not give two doses of medicine at once to make up for one missed dose.

2. My child threw up after taking Tylenol, should I give more?

It is best to wait. Even if you think that the medicine is lost, not all of it has been thrown up, and you don’t want to overdose the child. However, if you think your kid has missed a much-needed dose, consult the doctor before you administer another dose.

Use the medication prudently, and make sure you are giving the right dosage to your child. And do not be in a hurry to give paracetamol as and when your kid has a fever or a headache. Give the body some time to fight, and support it with some simple and straightforward home remedies. If things do not work, then give Tylenol in the prescribed dose.
