Diclofenac sodium is a nonsteroidal anti-inflammatory medicine (NSAID) that is used to treat a variety of ailments, including menstrual cramps, arthritis, joint pain, and musculoskeletal disorders. It functions as an NSAID by preventing the body from producing prostaglandins, which are chemicals that cause pain and inflammation. Diclofenac sodium assists in lowering prostaglandin production, which lessens inflammation and pain. There are several different ways to get this drug, including tablets, capsules, gels, creams, and injections. The illness being treated and the demands of the individual will determine the precise type and dosage.
