What is in the product?


Dulcolax® Suppositories for Adults contains bisacodyl which has a dual action: it stimulates the smooth muscles of the intestinal walls in charge of passing stool and increases the water content which helps soften the stool to favor evacuation. Thanks to the application directly into the rectum, the action is located where it’s needed. In short, Dulcolax® Suppositories facilitates the evacuation and unblocks your system within minutes.

How does it work?

Once in contact with the colon, the stimulant laxative bisacodyl contained in the suppository will accelerate the stool transition through the colon with its dual action: the rehydration of the stool in the large intestine will soften the stool and the stimulation of the activity of bowel muscles will cause your intestines to contract. This way, evacuation is facilitated, giving you the feeling of being unblocked in 20 minutes (depending on the individual) 2,4,5.

Dulcolax® Suppositories do not have to travel through your stomach and small intestine to become effective. The application directly into the rectum ensures that the active content is released exactly where it is needed. The active metabolite is minimally absorbed so there is no burden to the body.

  • Dulcolax® Suppositories for Adults can be purchased in pharmacies and parapharmacies.

  • Dulcolax® products, and any other laxatives, do not help with weight loss. They do not reduce the absorption of calories or nutrients. They can cause watery stools (diarrhea), abdominal cramps and dehydration.

  • There are many types of laxatives – each works somewhat differently to make it easier to have a bowel movement.

    Suppositories laxatives

    Medicated suppositories are a typically reliable fast-acting dosage form of stimulant laxatives that are inserted into the rectum. These suppositories which may contain bisacodyl or glycerin aid in moving stool out of the body by providing lubrication and stimulation. They stimulate the bowel muscles in the intestine to help encourage a bowel movement quickly within minutes.

    Rather than another type of laxatives, suppositories are an alternative form, to suit the needs of people having difficulties swallowing.

    Stimulant laxatives

    Stimulant laxatives including bisacodyl, the active substance in Dulcolax®, has a dual action: Stimulant laxatives induce water and salt transport into the gut which hydrates the stool and makes it easier to pass. In addition, stimulant laxatives stimulate the activity of bowel muscles causing your intestines to contract. These two effects jointly result in an acceleration of stool transit through the colon and have been proven to be very effective and safe in clinical studies. Effectively stimulating the bowel muscles speed up stool movement. They help get things moving.

    Stool Softeners laxatives

    Stool softeners are just that — products that help make hard, dry, painful stools softer. They work by softening the stool in the intestine, which makes it easier and more comfortable to pass. When used as directed, stool softeners are a safe, gentle way to keep things moving.

    Fiber supplements

    Fiber supplements add bulk to your stool. Bulky stools are softer and easier to pass. Fiber supplements are traditionally considered as the first-line treatment. They are generally safe, but may increase bloating, flatulence and abdominal pain, and may interfere with the absorption of some drugs.

    Osmotic laxatives

    Osmotic or saline laxatives help stool move through the large intestine by reducing intestinal fluid absorption. These laxatives contain poorly absorbed substances that hold additional water inside the colon, creating an osmotic gradient, drawing water into the bowel. This hydrates the stool and makes it easier to pass. As a result, saline laxatives help increase the number of bowel movements. An easier time in the bathroom and regular bowel movements? It’s a win-win.

  • When taking laxatives, side effects can occur during short and long-term treatments (as for any medication). As of today, there is no proof of a specific risk to the colon during long term laxative treatments. Based on experience, stimulant laxatives can be considered safe for long-term use if used as indicated in the patient information/leaflet7.

    If high doses are taken over extended periods of time, watery stools (diarrhoea), abdominal cramps and a clinically significant loss of fluid, potassium and other electrolytes can occur which can damage your health by causing disturbances of electrolyte and mineral balances. Sodium, potassium, magnesium, and phosphorus are electrolytes and minerals that are present in very specific amounts necessary for proper functioning of the nerves and muscles, including those of the colon and heart. Upsetting their balance can cause incorrect functioning of these vital organs. Kidney damage and muscle weakness have also been described in association with chronic laxative abuse4.

  • Available data do not indicate a risk for habituation or addiction 8, 9. Some people suffering from constipation symptoms need to use laxatives constantly to maintain bowel movements without complaints. These people with chronic constipation do not achieve regular bowel movements without complaints such as severe straining. But this constant use is not the result of prior laxative intake. It is rather their condition causing the need for constant use and this should not be misinterpreted as addiction.

    Addiction does not have a pharmacological basis because most laxatives are not absorbed and none cross the blood brain barrier which means that they do not reach the brain to cause physical addiction 8, 9.
