Chlorzoxazone + Diclofenac + Paracetamol is a combination of a muscle relaxant (Chlorzoxazone ) and two pain relieving medicines ( Diclofenac and Paracetamol). The muscle relaxant works on the centers in the brain and spinal cord to relieve muscle stiffness or spasm, thereby improving movement of muscles. The pain relieving medicines work by blocking the release of certain chemical messengers in the brain that cause pain and inflammation (redness and swelling).                                                                                                                                                                                COMMON SIDE EFFECTS:                                                                                                                                                    Nausea, Vomiting, Diarrhea, Headache, Dizziness, Insomnia (difficulty in sleeping), Vertigo, Constipation, Dyspepsia, Abdominal pain, Flatulence, Decreased appetite, Increased transaminase level in blood, Rash
