  • If you have any pain in the lower abdomen or if you have stomach cramps, fever, nausea or vomiting.
  • If you are pregnant.
  • If you have taken Dulcolax® already for a week without any
  • If you are taking any other medications, including those available without a prescription, herbal and complementary medicines.

Do not give Dulcolax® to a child unless the doctor tells you to.

A laxative should not be taken within two (2) hours of another medicine because the desired effect of the other medicine may be reduced.

You may experience dizziness and/or fainting (syncope) caused by a malaise triggered by abdominal spasm. If you experience abdominal spasm, avoid hazardous tasks such as driving or operating machinery.


Drugs that may interact with Dulcolax® include: diuretics (eg. hydrochlorothiazide), adreno-corticosteroids (eg. hydrocortisone, prednisone), and cardiac glycosides (eg. digoxin). This is not an all-inclusive list of examples.

Tell your doctor and pharmacist what prescription and nonprescription medications, vitamins and herbals you are taking.


Do not take more than the recommended daily dose. Overuse or extended use of any laxative can cause dependence for bowel function; do not take for more than a week without consulting a physician.

Usual dose:

For relief of constipation:

  • Adults and children over 12 years: One adult suppository
    Suppositories should take from about 15 minutes to 1 hour to stimulate a bowel movement.
    One Dulcolax® 10 mg suppository inserted as described below.


Unwrap the suppository from its foil covering. Dip the tip of the suppository for a few seconds in lukewarm water to soften the exterior. Lie down on your side and raise your opposite knee to your chest. Relax the buttock just before inserting the suppository to ease insertion. Gently insert suppository, lubricated pointed end first, high into rectum so that it will not slip out. Push the flat end of the suppository sideways to make sure that part of it touches the wall
of the rectum. Continue to lie down for a few minutes and hold the buttocks together to allow the suppository to dissolve in the rectum. Try to retain the suppository in the rectum as long as possible.


If high doses are taken, watery stool (diarrhoea), abdominal cramps, and loss of fluid, potassium and other minerals can occur. Dulcolax® when taken in chronic overdose may cause chronic diarrhoea, abdominal pain, kidney damage, and muscle weakness.

In case of overdose, contact your physician, pharmacist, or your regional Poison Control Centre immediately.


Dulcolax® may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away: abdominal discomfort (including abdominal cramps, abdominal pain, nausea, vomiting or diarrhoea), dehydration (with symptoms such as dry, sticky mouth, thirst), dizziness, fainting (syncope), swelling of the colon (large bowel), anorectal discomfort (discomfort involving the anus and rectum) and haematochezia (blood in stools).

If you have any of the following symptoms, stop taking Dulcolax® and call your doctor immediately: allergic reactions (including swelling of the face, lips, mouth, tongue or throat which may cause difficulty in swallowing or breathing).

This may not be a complete list of side effects. For any unexpected effects while taking Dulcolax®, contact your doctor or pharmacist.
