Lactulose is a synthetic sugar that is used to treat constipation. It works by pulling water from the body and into the colon, which helps to soften stool.

This drug is also used to reduce the amount of ammonia in the blood of patients with liver disease. It does this by drawing ammonia from the blood and into the colon, where it is released from the body.

The recommended dose for the treatment of acute or chronic constipation in adults is 15 mL of Lactulose liquid or syrup taken orally one time per day.

Contact your doctor if you experience any of these symptoms and they are persistent or severe: gas, diarrhea, and nausea.


Contact your doctor immediately if you experience serious symptoms of vomiting and stomach cramps or stomach pain.
