This medicine contains the active ingredient naproxen which is also called a non-steroidal anti-inflammatory drug (NSAID), or just 'anti-inflammatory'. NSAIDs are used to ease pain, stiffness and inflammation of conditions that affect muscles, bones and joints. Naproxen is also used to reduce pain and inflammation in rheumatic conditions such as arthritis, rheumatoid arthritis and ankylosing spondylitis, gout, lower back pain, strains, painful periods, and it is used after surgical operations.
Naproxen, as well as other NSAIDs, eases pain and inflammation by blocking the production of chemicals called ‘prostaglandins’, which are produced at sites of injury or damage.
