Paracetamol is an analgesic (pain reliever) and antipyretic (fever reducer). It blocks the release of certain chemical messengers in the brain that are responsible for pain and fever. Chlorzoxazone is a muscle relaxant. It works by acting on the centers in the brain and spinal cord to relieve the muscle stiffness or spasm.

Warnings and precautions

Never exceed the daily maximum printed on the pack. Paracetamol overdose damages the liver, and the damage can be silent for a day or two before it becomes serious. Check every other medicine you are taking. Paracetamol is in a very large number of cold, flu and pain combinations, and the doses add together. If you drink alcohol regularly, or have liver disease, ask your doctor what daily limit is safe for you. See a doctor if fever lasts more than three days, or pain more than five. This medicine causes drowsiness. Do not drive or operate machinery until you know how it affects you. Use it for the short course your doctor has prescribed — these are not intended for long-term use. Do not stop a long course abruptly without asking your doctor.

Do not take Spaz-M if

Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Not for people with severe liver disease, except under medical supervision. Not for people with myasthenia gravis or severe liver disease.

Interactions with other medicines

Regular alcohol use increases the risk of liver injury. Tell your doctor if you are on warfarin — regular high-dose paracetamol can affect it. Alcohol, sleeping tablets, antihistamines and opioid painkillers all add to the drowsiness, sometimes dangerously.

How to store Spaz-M

Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.
