Warnings and precautions

Drink plenty of water while taking any laxative, particularly the fibre-based ones — without it they can make constipation worse. Do not use stimulant laxatives daily over long periods without medical advice; the bowel becomes reliant on them. See a doctor if constipation is new and persistent in an adult over forty, or comes with blood, weight loss or severe pain.

Do not take Constez if

Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Not for anyone with a suspected bowel obstruction, or with severe abdominal pain of unknown cause.

Interactions with other medicines

Laxatives can reduce the absorption of other medicines taken at the same time.

How to store Constez Sachet

Store below 30°C in a dry place, away from direct sunlight. Keep out of the reach of children.

Expert advice for Constez Sachet

Increase fibre, fluids and physical activity — these treat the cause rather than the episode. Do not ignore the urge to go; a regular routine helps.
