How Long Does It Take for Dulcolax to Take Effect?
Dulcolax laxative tablets typically induce a bowel movement within 6 to 12 hours, according to WebMD. Quicker results may be obtained with Dulcolax laxative suppositories, which produce a bowel movement within 15 minutes to an hour.
Dulcolax laxative tablets are what’s described as a stimulant laxative. They are intended to stimulate the intestines and trigger a bowel movement. The tablet is coated to preserve the active ingredient until it reaches the area of the intestines where it is needed. Dulcolax laxative suppositories work much quicker, as insertion of suppository into the rectum allows for more direct stimulation of the intestines, as claimed by the Dulcolax website,.
