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 Lactihep 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.
