Dulcolax is a branded treatment for constipation and bowel irregularity that contains the active ingredient Bisacodyl, a stimulant laxative and stool-softener.
What is Dulcolax used for?
The treatment is used for the short term relief of occasional constipation, when other measures have failed. If experiencing constipation, the first recommendation is to try diet and lifestyle measures, such as increasing fluid and fibre intake and increasing physical activitity such as a daily walk or run. If this fails, a bulk-forming laxative such as Fybogel or an osmotic laxative such as Movicol or Laxido is recommended as first line treatment. Following this, if your bowel motions are soft but still difficult to pass, a stimulant laxative such as Dulcolax may be used for short- term relief.
How does Dulcolax work?
Bisacodyl, the active ingredient in Dulcolax, is a dual-action laxative. Its primary function is to stimulate the nerves that line the walls of the colon in order to get them to contract. This process, known as peristalsis, then encourages stools to move through the colon and into the rectum, making them easier and quicker to pass.
In addition, Dulcolax also softens stools in the colon by encouraging more water and salt to move through them. This makes especially hard or dry stools easier to pass than they otherwise would be.
How long does Dulcolax take to work?
Dulcolax is among the quicker over-the-counter oral remedies for constipation. After taking one tablet, it should begin to work in 6 to 12 hours. However, it’s important to remember that many people don’t feel the effects of Dulcolax at first. In fact, a lot of people report not feeling anything for some time after taking it, before feeling a sudden urge to pass a bowel movement around eight hours in.
