Common uses
For fever and pain relief.
Paracetamol is a medicine that is used for mild to moderate pain and fever in adults and children. Paracetamol is often used in people who cannot take anti-inflammatories (e.g. due to stomach ulcer), as it is gentle on the stomach.
Paracetamol is less likely than anti-inflammatories (NSAIDs) to cause worsening of asthma or an asthma attack.
For children, paracetamol is the most commonly prescribed medicine to reduce a high temperature or for pain relief.
It works by blocking the making of prostaglandins (pros-ta-glan-dins) which can cause pain (including headaches), fever (high temperature), and inflammation (swelling and redness). Paracetamol is not very good at reducing inflammation, but is very effective at reducing pain and fever. It is used both for acute pain (e.g. headache, accident) and for chronic pain (e.g. osteo-arthritis). It is sometimes used for cancer pain.
Paracetamol is available in tablets, capsules, soluble tablets, children's mixtures and suppositories.

The mixtures for children usually come in 120mg/5ml or 250mg/5ml. Take care that you use the correct amount according to the strength of the mixture.
It is very important not to take more than the recommended dose — too much will not give you any better pain relief, but is very dangerous. If you still have pain or fever after using the correct dose of paracetamol, check with your doctor. Paracetamol should take about 20 minutes to start to work.
