Lactulose is used to treat constipation.

Lactulose is not metabolised or absorbed by the body and the substance helps pull water into the colon, softening the stool. Lactulose also works by promoting peristalsis, pushing food through the digestive system.

This laxative syrup is suitable to be used by adults and children, including infants.

Lactulose (67.0% w/v), lactose and galactose.
