Dulcolax Tablets offer relief from constipation by gently stimulating the bowel and returning the body habit to its own natural rhythm. Dulcolax Tablets are considered a trusted and reliable treatment for constipation. Dulcolax are easy to take thanks to their special comfort coating, which ensures the active ingredient is released right where it’s needed. The coating resists the acidic digestive juices of the stomach and small intestine to dissolve only as it reaches the alkaline environment of the colon. Each tablet contains a precisely measured amount of the active ingredient bisacodyl that gently stimulates the bowel and colon to relieve constipation in 6-12 hours.
