You can find this medicine in many forms. Your child can chew it or drink it. It can also be given as a suppository. This is a small capsule you put in your child's rectum. It may be a good choice when your child can't keep anything in his or her stomach.

Make sure to use the right amount of this medicine. The correct dose depends your child's size and weight.

What to know about this medicine

  • Do not use this medicine if your child is allergic to it.
  • Follow all instructions on the label.
  • Talk to your doctor before you give your child the medicine if:
    • Your baby is younger than 3 months and has a fever. Your doctor will make sure that the fever is not a sign of a serious problem.
    • Your child has kidney or liver disease.
  • Call your doctor if you think your child is having a problem with his or her medicine.
  • Check with your doctor or pharmacist before you give your child any other medicines. This includes over-the-counter medicines. Make sure your doctor knows all of the medicines, vitamins, herbal products, and supplements your child takes. Taking some medicines together can cause problems.

How much to give (dosage): Give acetaminophen every 4 hours as needed. Do not give more than 5 doses in a 24-hour period. Dosages are based on the child's weight.

Caution: Make sure you understand what amount of medicine in millilitres (mL) to measure for your child’s dose. Speak to a pharmacist if you need help. A common concentration for use in babies is the Infants’ Tylenol which contains acetaminophen 80 mg in each 1 mL of medicine. For older children you may use the Children’s Tylenol liquid; this has less acetaminophen in each 1 mL of medicine. Children’s Tylenol contains 160 mg acetaminophen in 5 mL of medicine; it works out to 32 mg acetaminophen in 1 mL.

Note: If your doctor prescribes this medicine, use the dosage on the prescription. Do not use these.
