Bisacodyl 

(bis ak' oh dil)

WHY is this medicine prescribed?

Bisacodyl is used on a short-term basis to treat constipation. It also is used to empty the bowels before surgery and certain medical procedures. Bisacodyl is in a class of medications called stimulant laxatives. It works by increasing activity of the intestines to cause a bowel movement.

HOW should this medicine be used?

Bisacodyl comes as a tablet to take by mouth. It is usually taken the evening before a bowel movement is desired. Bisacodyl normally causes a bowel movement within 6 to 12 hours. Do not take bisacodyl more than once a day or for more than 1 week without talking to your doctor. Follow the directions on the package or on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take bisacodyl exactly as directed. Frequent or continued use of bisacodyl may make you dependent on laxatives and cause your bowels to lose their normal activity. If you do not have a regular bowel movement after taking bisacodyl, do not take any more medication and talk to your doctor.

Swallow the tablets whole with a glass of water; do not split, chew, or crush them.

Do not take bisacodyl within 1 hour after drinking or eating dairy products.

Are there OTHER USES for this medicine?

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

What SPECIAL PRECAUTIONS should I follow?

Before taking bisacodyl,

  • tell your doctor and pharmacist if you are allergic to bisacodyl, any other medications, or any of the ingredients in these products. Check the label or ask your pharmacist for a list of the ingredients.
  • tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
  • if you are taking antacids, wait at least 1 hour before taking bisacodyl.
  • tell your doctor if you have stomach pain, nausea, vomiting, or a sudden change in bowel movements lasting more than 2 weeks.
  • tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking bisacodyl, call your doctor.

A regular diet and exercise program is important for regular bowel function. Eat a high-fiber diet and drink plenty of liquids (eight glasses) each day as recommended by your doctor.

This medication usually is taken as needed. If your doctor has told you to take bisacodyl regularly, take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
