Key points about the safe use of paracetamol in children

  • paracetamol is a medicine to help reduce pain
  • your child doesn't need it for fever alone - if your child is miserable because of the fever, you can give paracetamol to make them more comfortable
  • too much paracetamol can be dangerous
  • keep all medicines out of reach of children, in a locked or latched cupboard
  • before each dose, check if your child still needs it
  • know the right dose to give and check the strength
  • give no more than 4 times in 24 hours
  • if someone else has been caring for your child, ask if they gave your child paracetamol, how much and when
  • check other medicines your child is taking - they may have paracetamol in them

Always measure doses exactly. Ask your pharmacist or nurse for an oral syringe - to give your child medicine by mouth.

What is paracetamol?

  • paracetamol is a medicine to help reduce pain
  • paracetamol is the name of the medicine but it has many brand names including Pamol, Avallon, Paracare and Panadol
  • it will not cause drowsiness or cause your child to sleep

Does my child need paracetamol?

You can use paracetamol for children and babies over 3 months old - younger babies must see the doctor.

  • you can use it for children and babies over 3 months old
  • younger babies must see the doctor
  • only give paracetamol if it's necessary
  • fever is a normal response to infection and is not in itself harmful, so you don't need to give paracetamol for fever alone
  • if your child is miserable because of the fever, you can give paracetamol to make them more comfortable

Paracetamol and immunisation

If your child is having the MenB (Bexsero) vaccine, they are more likely to get a fever or a high fever afterwards. For this reason, it's a good idea to give paracetamol to help lower any fever and make your child more comfortable. 

Check the advice about paracetamol for fever after MenB immunisation

Apart from when having the MenB vaccine, you don't need to give babies and children paracetamol before immunisation. If your child is miserable or distressed with a fever after immunisation, you can give a dose of paracetamol. 

Using paracetamol around the time of immunisation reduces the immune system response to immunisation when measured in a laboratory. But, there is no evidence that the reduced response decreases protection in children against the diseases they were immunised against.

How long will it take for liquid paracetamol to work for my child?

It varies between individuals but paracetamol seems to have the maximum effect between 1 ½ and 3 hours after you give the dose. Pain levels and temperature may start to come down before this.

What is the correct dose of paracetamol for my child?

Wait at least 4 hours between doses - give no more than 4 times in 24 hours.

  • the dose of paracetamol depends on your child's weight and the strength of the paracetamol you have
  • always measure doses exactly - ask your pharmacist or nurse for an oral syringe
  • weigh your child, then check the dosing table below
  • check the strength of the paracetamol you have
  • ask the pharmacist, doctor or nurse to show you

It's important your child does not take more than the daily recommended dose. If you child takes too much - all at once or over a period of days - paracetamol can damage their liver.

  • 2 tablets (500mg each) if your child is more than 66kg

What do I need to do before every dose of paracetamol for my child?
