Nimesulide+Paracetamol+Tizanidine is used in pain due to muscle spasm.

Nimesulide + Paracetamol + Tizanidine is a combination of three medicines: Nimesulide , Paracetamol and Tizanidine which relieve pain and relax the muscles.Nimesulide is a non-steroidal antiinflammatory drug (NSAID) and Paracetamol is an antipyretic (fever reducer). They work by blocking the release of certain chemical messengers in the brain that cause pain and fever. Tizanidine is a muscle relaxant. It works on brain and spinal cord to relieve muscle stiffness or spasm and to improve pain and movement of muscles.

Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them
