Piroxicam is a medicine called a non-steroidal anti-inflammatory drug. It is often referred to simply as 'an anti-inflammatory', or sometimes as an 'NSAID'. It works by preventing the production of some natural chemicals in your body which cause pain and inflammation. This leaflet deals with piroxicam when it is applied topically to the skin. Piroxicam can also be taken by mouth in the form of tablets and capsules, although other medicines are usually preferred to it.
