About naproxen

What is naproxen used for?

Naproxen is a type of analgésico antiinflamatorio called non-steroidal anti-inflammatory drugs (NSAIDs), or just 'anti-inflammatories'.

It is used to treat painful conditions such as artritis, esguinces y distensiones, dolor de espalda, period (menstrual) cramps, y gout pain.

Naproxen is available on prescription. Short courses of tablets for the treatment of period pain are also available to buy at pharmacies.

How does naproxen work?

Naproxen works by blocking the effect of chemicals in your body, called cyclo-oxygenase (COX) enzymes. These enzymes help to make other chemicals in the body, called prostaglandins.

Some prostaglandins are produced at sites of injury or damage, and cause pain and inflammation. By blocking the effect of COX enzymes, fewer prostaglandins are produced, which means pain and inflammation are eased.
