Diclofenac is a non-opioid analgesic medicine that is used to relieve pain, inflammation and fever. It belongs to the group of medicines called Non-Steroidal Anti-Inflammatory Drugs (NSAIDs).
Diclofenac works by blocking the action of the enzyme cyclooxygenase (COX), which reduces the production of prostaglandins. Prostaglandins are chemicals in the body that cause pain, swelling and inflammation.
