Dulcolax is a gastro-resistant tablet containing 5mg bisacodyl, designed to provide overnight relief from constipation. This pack contains 40 tablets that offer predictable and effective constipation relief within 6-12 hours of taking the medication. The active ingredient bisacodyl works as a stimulant laxative by increasing bowel movements. The gastro-resistant coating ensures the medicine passes through the stomach and is released in the intestine where it is needed. Take tablets at bedtime for overnight relief. Always read the label and follow dosage instructions. Not recommended for children under 12 years without medical advice. Store in a cool, dry place away from direct sunlight.
