Uses

Quick Answer

Duphalac Syrup (lactulose) is a laxative used to treat constipation in adults and children. It draws water into the bowel to soften stools. At higher doses, doctors also use it for hepatic encephalopathy, a brain problem caused by severe liver disease, because it lowers ammonia levels in the blood.

Primary Uses at a Glance

Chronic constipation

Duphalac Syrup is used for long-lasting constipation. Lactulose is not absorbed; it draws water into the bowel, which softens the stool and makes it easier to pass.

As advised by your doctor or pharmacist. Standard adult dose: 15 to 45 ml a day to start, then 15 to 30 ml a day.

Occasional constipation

It is also used for short episodes of constipation. It can take 2 to 3 days of regular use before it starts to work.

As advised by your doctor or pharmacist. Standard adult dose: 15 to 45 ml a day to start, then 15 to 30 ml a day.

Reducing ammonia levels in patients with liver impairment

In severe liver disease, ammonia can build up and affect the brain (hepatic encephalopathy). Lactulose lowers ammonia levels. This use is only under a doctor's care.

Only on a doctor's advice. Usual adult dose: 30 to 45 ml three to four times a day, adjusted to give two to three soft stools a day.
