What is Dulcolax?
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 to alleviate occasional or chronic constipation by stimulating bowel activity and making stools easier to pass. In addition, Dulcolax is also sometimes used to manage the effects of neurogenic bowel dysfunction - a condition in which nerve damage makes a person unable to control their bowel movements - and by doctors and nurses to prepare medical procedures.
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.
How should I take Dulcolax?
Because Dulcolax tends to take effect at least six hours after it is taken, it’s recommended that one tablet be taken with water just before you go to bed. This is so that the medication will have begun to work upon waking up, increasing the likelihood you’ll be able to pass stool in the morning.
You can take Dulcolax with or without a meal. However, you must not drink milk, use indigestion remedies or take acid reflux medication at the same time you take Dulcolax. This is because it will cause the Dulcolax to not work properly. Leave a one hour gap between taking Dulcolax and these things.
Who can’t take Dulcolax?
As an over-the-counter treatment, Dulcolax is usually very safe for adults suffering from occasional or chronic constipation. However, it’s important to remember that Dulcolax is not suitable for everyone. In particular, you must tell your GP or pharmacist before taking Dulcolax if you have:
- Signs of dehydration
- Been sick or you feel sick
- Severe stomach pain
- A serious stomach-related illness, such as a blockage in your bowel, ulcerative colitis, appendicitis, Crohn's disease or muscle weakness in your bowel that stops it moving liquid and food properly
- An intolerance to certain sugars (the tablets contain small amounts of lactose and sucrose)
What are the side effects of Dulcolax?
Some people who take Dulcolax will experience side effects. These are, however, usually mild. They include:
- Feeling sick
- Abdominal pain or cramps
Rarely, Dulcolax can cause more serious side effects. Contact your doctor right away if you experience any of the following after taking Dulcolax:
- Feeling dizzy
- Bloody stools
- Being sick
How should I store Dulcolax?
Dulcolax should be stored in a dry, cool environment that does not exceed 25°C.
Always read the patient information leaflet before commencing treatment.
