Ibuprofen (Brufen, Nurofen)

Ibuprofen is an anti inflammation medicine (a non steroidal anti inflammatory drug or NSAID). It can relieve mild to moderate pain, reduce swelling and control high temperature (fever).

It is also known by the brand names Brufen and Nurofen. Ibuprofen is also part of many other painkiller combination medicines.

How ibuprofen works

Ibuprofen controls pain by blocking chemical messages in the brain that tell us we have pain. It also reduces swelling (inflammation).

How you have ibuprofen

There are many different ways of having ibuprofen. You can have it as:

tablets
capsules
caplets
soluble granules
a syrup that you drink
a gel or spray

You can get Ibuprofen on prescription from your doctor. Or you can buy it from a pharmacy or other shops such as your local supermarket. Check with your nurse or doctor before you start taking ibuprofen if you have a history of stomach ulcers, asthma or problems with your heart, kidneys or liver.

Taking your tablets or capsules

You must take tablets and capsules according to the instructions your doctor or pharmacist gives you.

You should take the right dose, no more or less,

Take Ibuprofen tablets, capsule or caplets with a glass of water. If you have a sensitive stomach or a history of stomach ulcers, you should take Ibuprofen with or after food.

When you have ibuprofen

When you take ibuprofen depends on the amount you need to control your pain. You might take it at the same time as other painkillers or in between taking them.

The normal dose for an adult is 1 to 2 tablets every 4 to 6 hours. You can take up to 1, 600 mg in 24 hours. Always check the packet to see how much ibuprofen each tablet or capsule contains. Usually they are either 200 mg or 400 mg, but 600 mg and 800 mg are also available.

Your doctor might prescribe a higher dose if needed.

Having ibuprofen for pain control can hide a high temperature caused by chemotherapy treatment. Take your temperature beforehand and if you have a high temperature contact your advice line before taking ibuprofen.
