The World’s #1 Non-Prescription Laxative Brand
Dulcolax® - Suppositories

Dulcolax® Suppositories

Fast relief (15 to 60 minutes)

  • When you’re constipated, you may feel bloated, uncomfortable and just not yourself. Stop focusing on your constipation and get back to enjoying life.
  • Get fast relief you can count on in 15 to 60 minutes with Dulcolax® Suppositories.
  • They contain the same active ingredient as Dulcolax® Tablets, in a comfort-shaped suppository format.

Dulcolax® Laxative Suppositories have the same active ingredient you have come to trust in Dulcolax® Laxative Tablets.

Dulcolax® Laxative Suppositories work by releasing the active ingredient, bisacodyl, in the rectum, which stimulates the bowel muscles while also accumulating water in the intestines. The effect is to soften the stool and to make it pass through more quickly, generally providing relief in 15 to 60 minutes, so you can feel like yourself again fast.

Dulcolax® Suppositories are specially shaped so that they are easy to insert gently into the rectum.

  • 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.

What Dulcolax® is used for?

Dulcolax® is used for relief of occasional constipation. Under medical supervision Dulcolax® is also used to empty the bowels before and after surgery and before examination.


Dulcolax® should not be used:

  • If you have severe abdominal pain associated with nausea and vomiting.
  • If you have intestinal obstruction (ileus), acute inflammatory bowel disease, or appendicitis.
  • If you are suffering from severe dehydration.
  • If you are allergic to the drug or any component of it (see non-medicinal ingredients).


Warnings & Precautions:

BEFORE you use Dulcolax® talk to your doctor or pharmacist:

  • If you have ever had an allergic reaction to this or any other medicines.
  • 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 effect.
  • If you are taking any other medications, including those available without a prescription, herbal and complementary medicines.

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.


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.
