Bisacodyl is a stimulant laxative available in over-the-counter (OTC) medicines that help temporarily relieve constipation. Bisacodyl can be found in single-ingredient oral stimulant laxative medicines and in single-ingredient stimulant laxative suppositories.
Bisacodyl has been reviewed by the U.S. Food and Drug Administration (FDA) and is safe and effective when used according to directions on the Drug Facts label. Bisacodyl laxatives taken orally generally produce a bowel movement within six to 12 hours, while bisacodyl rectal suppositories provide relief within approximately 15 minutes to one hour. If you do not have a bowel movement after using a bisacodyl laxative medicine, contact your healthcare provider because this may be a sign of a more serious condition.
