Dulcolax Laxative Tablets are the #1 doctor recommended brand and provide gentle, predictable overnight relief. They may be used to temporarily relieve occasional constipation and irregularity. The product generally produces bowel movement in 6 to 12 hours. Adults and children over 12 can take 1 to 3 tablets in a single daily dose for up to 7 days. If this is the first time taking a laxative for constipation, we recommend taking 1 to 2 tablets in a single daily dose. Take tablets 30 to 60 minutes before your normal bedtime to produce a bowel movement the next morning. With experience, you may increase your daily dosage to 2 or 3 tablets, if needed. For children under 12 years of age, refer to the Dulcolax® Laxative Tablets Drug Facts for dosing information.
