How does it work?
Diclofenac belongs to a group of medicines called non-steroidal anti-inflammatory drugs (NSAIDs).
It works by blocking the action of a substance in the body called cyclo-oxygenase. Cyclo-oxygenase is involved in the production of various chemicals in the body, some of which are known as prostaglandins. Prostaglandins are produced in response to injury or certain diseases and would otherwise go on to cause pain, swelling and inflammation. Arthritic conditions are one example of such a diseases.
Diclofenac is used to relieve pain and inflammation in a wide range of conditions, including arthritis, gout, sprains, fractures, back pain and following minor surgery.
All the medicines in the NSAID group reduce inflammation caused by the body's own immune system and are effective painkillers, but must be taken with or after food to avoid stomach related side effects.
