Duphalac oral solution offers relief from constipation for all the family.

Duphalac oral solution is a syrup that contains a laxative called lactulose. May contain small amounts of milk sugars (e.g. lactose), galactose, epilactose or fructose.

As a prebiotic substance, lactulose intensifies the growth of Bifidobacterium and Lactobacillus, while Clostridium and Escherichia coli may be suppressed, leading to alleviation of constipation.


  • Relieves chronic constipation
  • Little absorption into body
  • Suitable for long-term use

Made in Netherlands


Take Duphalac diluted or undiluted. Swallow the medicine quickly. Do not keep it in the mouth. Take the dosage preferably once a day at the same time. During treatment with laxatives, drink sufficient amounts of fluids (6 to 8 glasses).

Based upon treatment response the doctor may adjust the starting dose to the maintenance dose after a few days.

How long does it take for Duphalac to work?

Several (2-3) days of treatment may be needed before treatment effect occurs.
