Lactulose (IPA: ˈlæktjʊləʊz) is a synthetic sugar used in the treatment of constipation1 and hepatic encephalopathy, a complication of liver disease. It is a disaccharide (double-sugar) formed from one molecule each of the simple sugars (monosaccharides) fructose and galactose. The commercial syrup used for treatment of constipation is dyed yellow-orange. It is produced commercially by isomerization of lactose.

In the treatment of chronic constipation, the metabolites of lactulose draw water into the bowel, causing a cathartic effect through osmotic action. Unlike other laxatives that are recommended for temporary relief, lactulose can be taken daily for decades. It is safe for people of all ages, except for those in a very small percentage of the population that are galactose intolerant. Dosage may have to be adjusted over time to produce the desired effect because the laxative effect can reduce somewhat with daily treatment.
