Lactulose is a laxative made from lactose. It treats chronic constipation. It also treats or prevents hepatic encephalopathy or coma, which are conditions that could result from liver disease.
LACTULOSE (LAK tyoo lose) treats constipation. It works by increasing the amount of water your intestine absorbs. This softens the stool, making it easier to have a bowel movement. It also increases pressure, which prompts the muscles in your intestines to move stool. It belongs to a group of medications called laxatives.
