What is ibuprofen?

Ibuprofen belongs to a group of medicines known as non-steroidal anti-inflammatory drugs (NSAIDs). Ibuprofen is used to treat pain from swelling and injury. Ibuprofen should start to work within 20 to 30 minutes after taking it. Ibuprofen is also used to treat fever – see below does my child need ibuprofen for fever?

• Use ibuprofen only if necessary to reduce fever or pain.
• If it’s not working, or if you need to use it for more than 2 days, your child needs to see a doctor. 
• For long-term pain, eg arthritis, your child may need to take ibuprofen regularly.

Giving your child both paracetamol and ibuprofen

It is OK to give paracetamol and ibuprofen, but be very careful not to give too much of either medicine. Write down when you give each dose of paracetamol and ibuprofen so you don't give your child too much. Read more about giving paracetamol safely to children.  

Does my child need ibuprofen for fever?

Fever (temperature over 38°C) is a normal response to infection and isn't harmful, so you don't need to give medicine for fever alone. If your child has a fever AND is miserable, it is better to give them paracetamol. You don't need to give babies and children medicine before or after vaccination. This may reduce the effectiveness of childhood vaccinations.

Who may not be able to take ibuprofen?

Ibuprofen isn't suitable for some children. To make sure it's safe for your child, check with a pharmacist or doctor before giving ibuprofen, especially if your tamariki/child:

• has had an allergic reaction to ibuprofen or any other medicine
• has asthma
• has had stomach, heart, liver or kidney problems
• has a health problem with an increased risk of bleeding
• has an inflammatory bowel disease, such as Crohn's disease or ulcerative colitis
• has any signs of dehydration.

Babies younger than 3 months old must see the doctor first.

Do not give ibuprofen for chickenpox unless it has been recommended by a doctor. It can cause a serious skin reaction.

Ibuprofen comes in different strengths

Ibuprofen comes as liquid, chewable capsules, tablets and capsules. These come in different strengths and you can get some from a pharmacy without a prescription.

• Nurofen For Children®
• Advil®
• Nurofen®.

The dose for each child is based on their age and weight

If you are giving ibuprofen to your child and you're not sure how much to give them, always check with your pharmacist. 

You can also use the Ibuprofen Dose Calculator as a guide. Weigh your child and use the calculator to work out their correct dose.

• Don't use the same dose for other children unless they are the same age and weight.
• When measuring the dose of liquid ibuprofen, use a medicine syringe or medicine spoon. You can get these from your pharmacy. Don't use a kitchen spoon as it won't give you the right amount. Read more: tips on how to give medicines to babies and children.

How often should I give my child ibuprofen?

If your child needs it, you can give ibuprofen 3 or 4 times a day. Your pharmacist or doctor will tell you how often to give it. It is important to space the doses evenly through the day.

• 3 times a day: Wait at least 6 hours before giving the next dose. It should be given once in the morning, once in the early afternoon and once in the evening, for example 8 am, 2 pm and 8 pm.
• 4 times a day: Wait at least 4 hours before giving the next dose. It should be given first thing in the morning, at about midday, late in the afternoon and at bedtime, for example, 8 am, midday, 4 pm and 8 pm.
