Lactulose Solution is a proven remedy to help relieve constipation.  A change of diet, a lack of exercise, ignoring the urge to have a bowel movement, some medications and some diseases can all impact on your risk of constipation. It is important to remember that constipation can become serious if left for too long without treatment.

Recommended for:

  • Pregnant women
  • Nursing mothers
  • Children with constipation
  • People who recently underwent surgery
  • Elderly people or people with sever and/or chronic constipation

How does it work?

Lactulose Solution softens stools and promotes their movement through the bowel. It may take between 24 and 72 hours before normal defecation occurs. Increasing fibre intake in your diet, drinking plenty of fluids and exercise can be helpful in treating and preventing constipation.

About Lactulose Solution:

Lactulose is a synthetic disaccharide, a sugar molecule composed of two smaller sugar molecules bonded together, in this case fructose and galactose. It is not metabolised or absorbed by the body. Rather, the bacteria in the colon or large bowel break the lactulose down into acids. These acids pull water into the colon and soften the stool. Peristalsis, the movement of the food through the intestines, is also promoted through the actions of lactulose. Bowel evacuation becomes much easier as a result.


Adults and adolescents: The starting dose is 15 - 45ml or 1 - 3 sachets per day. After this the dose can be adjusted to 15 - 30ml or 1 - 2 sachets daily.

Children 7 to 14 years: The starting dose is 15ml or 1 sachet daily. After this the dose can be adjusted to 10 - 15ml or 1 sachet daily.

Children 1 - 6 years: The usual dose is 5 - 10ml daily. Infants under 1 year: The usual dose is up to 5ml daily.

Use in Children: Use of laxatives in children, infants, and babies should be exceptional and under medical supervision because it can influence the normal reflexes for passing stools.

Please do not give Duphalac to children (under 14 years) before consulting your doctor for prescription and careful supervision. 


Use only as directed.

Incorrect use could be harmful.

If symptoms persist, consult your doctor.

The prolonged use of laxatives is undesirable.

You should carefully read all product packaging and labels prior to use.
