Bisacodyl is a stimulant laxative, according to the National Institutes of Health. Bisacodyl works by stimulating the intestines to cause bowel movements. It is a short-term treatment for constipation, and it is also used to clear the bowels before certain medical procedures.
Bisacodyl is an oral medication that comes in a tablet form, says the National Institutes of Health. It is usually effective within 12 hours. Patients should follow the directions on the label and consult their doctor if they require clarification or advice for their specific situation. Bisacodyl should not be taken frequently or for extended periods of time, as it may cause laxative dependency and affect normal bowel activity.
