Necfen MR 250mg/50mg/500mg Tablet is used in the reduction of musculoskeletal pain due to tissue injury, resolution of post surgery inflammation and oedema (swollen tissue with fluid). Pain can be temporary (acute) or long-term (chronic) in nature. Musculoskeletal pain can be caused due to soft tissue (muscle, tendon, and ligaments) injury. Extreme tissue pain and inflammation caused due to sprains, strains or trauma or post-surgery may require a prolonged amount of time to heal.

Necfen MR 250mg/50mg/500mg Tablet is a fixed-dose combination composed of three medicines namely: Diclofenac, Paracetamol and Chlorzoxazone. Diclofenac works by blocking the action of a chemical messenger known as cyclo-oxygenase (COX), which causes pain and swelling at the injured or damaged tissue site. Paracetamol acts as a mild analgesic (mild pain reducer) and antipyretic (fever reducer), which enhances the pain relief action of Diclofenac. The third medicine, Chlorzoxazone, is a muscle relaxant that helps by blocking nerve impulses or pain sensations sent by the brain and causes relaxation of muscles.
