What is aspirin?

Aspirin is used to relieve mild to moderate pain, fever (a temperature higher than 38.5°C) and reduce inflammation. It is one of a group of medicines called non-steroidal anti-inflammatory drugs (NSAIDs).

The main effect of NSAIDs is to reduce inflammation, which the body produces in reaction to an injury or infection, as a way of healing the body.

Low-dose aspirin (up to 150 mg a day) can also be taken for a long period of time to act as a ‘blood thinner’, helping to prevent a heart attack or stroke – see Aspirin (anti-clotting-medicine).

Note about medicines names

Most medicines have two names: the active ingredient and the brand name. The active ingredient is the chemical in the medicine that makes it work. The brand name is the name given to the medicine by its manufacturer. There may be several brands that contain the same active ingredient. This website uses active ingredient names, with brand names in brackets. We also discuss medicines in groups or ‘classes’, when their effects or actions are very similar.

To find out more about active ingredients and brand names read our brand choices information.
