Thiocolchicoside is a muscle relaxant. It works on the centres in the brain and spinal cord to relieve muscle stiffness or spasm and to improve pain and movement of muscles.

Warnings and precautions

Take it with or just after food, and for the shortest time that works. Stop and seek urgent care for black or tarry stools, vomiting blood, or severe stomach pain — this group can cause bleeding from the stomach. Long or high-dose use raises the risk of heart attack, stroke and kidney injury, particularly in older people and those already at risk. Avoid if you are dehydrated or have an illness with vomiting or loose motions — the kidneys are vulnerable then. Must be avoided in the last three months of pregnancy. 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 Ark Th4 if

Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Not for people with an active stomach ulcer, severe kidney or heart failure, or asthma triggered by aspirin or anti-inflammatory painkillers. Not in the third trimester of pregnancy. Not for people with myasthenia gravis or severe liver disease.

Interactions with other medicines

Combining with a blood thinner or aspirin sharply raises the bleeding risk. Reduces the effect of blood pressure medicines and water tablets, and together with them can harm the kidneys. Never take two anti-inflammatory painkillers at the same time. Alcohol, sleeping tablets, antihistamines and opioid painkillers all add to the drowsiness, sometimes dangerously.

How to store Ark Th4 Tablet

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