What is ibuprofen?

Ibuprofen is a type of anti-inflammatory pain-relief medicine that treats fever and mild to moderate pain caused by inflammation. It belongs to a group of medicines called non-steroidal anti-inflammatory drugs, or NSAIDs.

How does ibuprofen work?

Ibuprofen works on one of the body’s chemical pathways for pain. It reduces your body’s ability to make prostaglandins — these are the natural chemicals that trigger pain, inflammation and fever.

With fewer prostaglandins in your body, pain and inflammation are reduced, and your fever goes down.

What is ibuprofen used for?

Ibuprofen can be used for the short-term relief of fever, mild to moderate pain and inflammation (redness, swelling and soreness).

Ibuprofen might also reduce some of the symptoms of:

• headaches (including migraines or tension headache)
• sinus pain
• toothache and pain after dental procedures
• backache and muscular aches and pains
• period pain
• sore throat
• arthritis

Ibuprofen provides only temporary relief — it won't cure your condition.

What forms of ibuprofen are available?

Ibuprofen is available in different:

• brands
• forms (for example, tablets, capsules and liquids)
• strengths
• packaging
• pack sizes

Some products combine ibuprofen with other medicines. If you are taking more than one pain reliever, make sure you don’t ‘double-up’ and accidentally take two medicines that contain ibuprofen.

You can buy ibuprofen in various ways — with a prescription, or without a prescription from pharmacies, convenience stores, service stations and supermarkets.

Babies and children need lower doses of ibuprofen than adults. Ask your pharmacist before buying ibuprofen for your child — there are formulations that are specially designed for children of different ages.

When should I speak to my doctor?

There can be extra risks if you take ibuprofen when you are over 65, have gastro-oesophageal reflux disease (GORD or 'reflux') or a stomach ulcer,so ask your doctor about ibuprofen before taking it. Ibuprofen, like other NSAIDs, can also make heart, liver or kidney disease worse.

Talk to your doctor before taking ibuprofen if you have asthma or are already taking aspirin to prevent heart disease.

Also, speak to your doctor if you:

• experience side effects that trouble you
• have signs of an allergic reaction
• have a health condition or are taking medicine that may affect how your body reacts to ibuprofen
• find that ibuprofen isn’t relieving your pain or fever — check with your doctor before using ibuprofen for longer than a week or so.
• are or become pregnant or start breastfeeding

See the CMI for full details about when to speak with your doctor before or after you have started taking ibuprofen.

Are there alternatives to ibuprofen?

If you’re treating fever or mild to moderate pain, ask your pharmacist if you can use paracetamol in place of ibuprofen.

For pain or inflammation-related swelling, ask your doctor or pharmacist for another option if ibuprofen is not suitable for you. Your health professional may suggest you try:

• paracetamol
• another medicine from the NSAID family
• a medicine that combines codeine with paracetamol or ibuprofen in the same tablet

If your pain is severe, your doctor may prescribe you a stronger pain reliever.
