Paracetamol is recommended as an alternative to ease short-term pain or reduce a high temperature.
Ibuprofen appears in breast milk in small amounts, so it's unlikely to cause any harm to your baby while you're breastfeeding.
Ibuprofen may be given to children aged three months or over who weigh at least 5kg (11lbs) to relieve pain, inflammation or fever.
Your GP or another healthcare professional may recommend ibuprofen for younger children in certain cases – for example, this may be to control a fever after a vaccination if paracetamol is unsuitable.
If your baby or child has a high temperature that doesn't get better or they continue to experience pain, speak to your GP or call NHS 111.
Make sure you use ibuprofen as directed on the label or leaflet, or as instructed by a health professional.
How much you can take depends on your age, the type of ibuprofen you're taking and how strong it is.
The painkilling effect of ibuprofen begins soon after a dose is taken, but the anti-inflammatory effect can sometimes take up to three weeks to get the best results.
Ibuprofen shouldn't be used to treat conditions that are mainly related to inflammation.
Don't take more than the recommended dose if it isn't relieving your symptoms.
Contact your GP or call NHS 111 if your symptoms get worse or last more than three days despite taking ibuprofen.
Ibuprofen can react unpredictably with certain other medicines. This can affect how well either medicine works and increase the risk of side effects.

Taking too much ibuprofen, known as an overdose, can be very dangerous.
If you've taken more than the recommended maximum dose, go to your nearest accident and emergency (A&E) department as soon as possible.
It can be helpful to take any remaining medicine and the box or leaflet with you to A&E if you can.
Some people feel sick, vomit, have abdominal pain or ringing in their ears (tinnitus) after taking too much ibuprofen, but often there are no symptoms at first. Go to A&E even if you're feeling well.
