Aspirin is an everyday painkiller for aches and pains such as headache, toothache and period pain. It can also be used to treat colds and flu-like symptoms, and to bring down a high temperature.
Aspirin is known as an acetylsalicylic acid. It also belongs to a group of medicines called non-steroidal anti-inflammatory drugs (NSAIDs).
Aspirin combined with other ingredients is also available in some cold and flu remedies.
You can buy most types of aspirin from pharmacies, shops and supermarkets. Some types are only available on prescription.
Aspirin comes as tablets or suppositories – medicine that you push gently into your anus (bottom). It also comes as a gel for mouth ulcers and cold sores.
If you've had a stroke or heart attack, or are at high risk of a heart attack, your doctor may recommend that you take a daily low-dose aspirin. Some women may also be prescribed low-dose aspirin while they’re pregnant.
This is different to taking aspirin for pain relief. Only take low-dose aspirin if your doctor recommends it. Read our information on low-dose aspirin.
