Official answer


After taking Dulcolax tablets you should have a bowel movement within 12 to 72 hours. Dulcolax suppositories generally produces bowel movements in 15 minutes to 1 hour. Different people may however feel the effects at different times.

Dulcolax (bisacodyl) is a laxative that stimulates bowel movements. Dulcolax is used to treat constipation or to empty the bowels before surgery, colonoscopy, x-rays, or other intestinal medical procedure.
