Dulcolax is a gastro-resistant laxative medication containing 5mg bisacodyl per tablet. This pack contains 40 tablets designed to provide predictable, overnight relief from constipation within 6-12 hours of taking the dose. Dulcolax tablets have a special gastro-resistant coating that allows them to pass through the stomach and work directly in the intestine. The active ingredient bisacodyl stimulates bowel movements to provide effective constipation relief. The tablets should be swallowed whole with water, preferably in the evening for overnight relief. Do not take with dairy products, antacids, or stomach acid reducers. This medication is for occasional use only and should not be used for extended periods without medical supervision.
