Dulcolax tablets are used for the short-term relief from occasional constipation by stimulating the muscles of the bowel. The active ingredient is bisacodyl which belongs to a group of medicines called laxatives. These tablets are often used in a hospital to empty a person’s bowel before childbirth, surgery or radiological investigations. Dulcolax tablets are gastro-resistant tablets which means that they work only where it is needed.

This medicine does not help with weight loss. 

What is constipation?

normal and regular bowel movement is important for most people. however, what is “normal and regular” varies from person to person. some may have a bowel movement every day, others less often. whatever it is like for you, it is best that your bowel movement has a regular pattern:

  • constipation is an occasional problem for some people. for others, it may happen more often
  • it happens when the normal muscle actions in the bowel (large intestine) slow down. this can mean that material is not easily eliminated from the body

The cause of constipation is often not known. It can be associated with:

  • sudden change of diet
  • a diet with not enough fiber
  • loss of ‘tone’ of the bowel muscles in older people
  • pregnancy
  • medicines such as morphine or codeine
  • having to stay in bed for a long time
  • lack of exercise

Whatever the cause, constipation can be uncomfortable. It may make you feel bloated and heavy or generally “off colour”. Sometimes it causes headaches.

These healthy tips are recommended to try to prevent constipation from happening:

  • eat a balanced diet including fresh fruit and vegetables
  • drink enough water so that you do not become dehydrated
  • keep up your exercise and stay fit
  • make time to empty your bowels when your body tells you

  • Swallow the tablets whole with water
  • Milk, antacids or proton pump inhibitors (medicines which reduce stomach acid) should not be taken within one hour before or after taking Dulcolax tablets. This is because they will stop the tablets from working properly.

Adults and children over 10 years

  • Take one or two tablets (5 or 10 mg) daily before bedtime
  • If you have not taken Dulcolax tablets before, start with one tablet and increase to two if necessary
  • When your bowel regularity has returned to normal, the dose can usually be stopped

Children aged between 4 and 10 years

Dulcolax tablets should only be given to children between the ages of 4 and 10 if recommended by a doctor. The usual dose for children is:

  • One tablet (5 mg) daily before bedtime

  • You have inflammation of the bowel (small or large intestine)
