Aceclofenac+Paracetamol+Tizanidine is used for muscular pain.

Aceclofenac + Paracetamol + Tizanidine is a combination of three medicines: Paracetamol, Aceclofenac, and Tizanidine. Paracetamol is an antipyretic (fever reducer) and Aceclofenac is a non-steroidal antiinflammatory drug (NSAID). They work by blocking the release of certain chemical messengers in the brain that cause fever and pain respectively. Tizanidine is a muscle relaxant. It works on the centers in the 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
