How does this medication work? What will it do for me?
Lactulose is an osmotic laxative. It is used for the relief of constipation, including chronic constipation, as directed by your doctor. It works over a period of about 24 to 48 hours. The liquid reaches your intestines virtually unchanged. Once there, the bacteria in your bowel split lactulose into its active parts. The active parts increase the action of your bowel and keep water in your bowel so that stools are moved through and are easier to pass.
Lactulose is also used to treat encephalopathy, a disorder of the brain causing confusion or mental problems as a result of liver disease or liver failure.
