What Is Lactulose Syrup 10gm/15mL?

Lactulose syrup is a synthetic sugar solution that is not absorbed in the small intestine. In the colon, it is broken down by bacteria into acids that draw water into the bowel, softening stool and promoting bowel movements. The same process also traps ammonia in the colon so it can be removed from the body, which is why lactulose is used in hepatic encephalopathy, a complication of liver disease. It is available by prescription as a 10 gm/15 mL syrup, sold under the brand name Enulose.

What Does Lactulose Syrup 10gm/15mL Treat?

Constipation (chronic constipation)
Hepatic encephalopathy (portal-systemic encephalopathy)
Reduction of elevated blood ammonia in liver disease
Prevention of recurrent hepatic encephalopathy episodes

Lactulose Syrup 10gm/15mL Dosage

Constipation: 15–30 mL (10–20 gm) by mouth once daily; may increase to 60 mL daily.
