Adults and children 12 years of age and over 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 starting with the lower dose (1 tablet), increasing up to 3 the following days if needed. We recommend taking the dose 30 to 60 minutes before your normal bedtime to produce a bowel movement the next morning. For children under 12 years of age, refer to the Dulcolax Tablets Drug Facts for dosing information. If you are still constipated after 7 days using the product, stop taking it and consult a doctor.
