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.
In addition to its desired action, this medication may cause some side effects, notably:
- it may cause stomach ache and cramps;
- it may cause diarrhea;
- it may cause gas and bloating;
- it may cause nausea and vomiting.
Each person may react differently to a treatment. If you think this medication may be causing side effects (including those described here, or others), talk to your health care professional. He or she can help you to determine whether or not the medication is the source of the problem.
