Lactulose Solution (Constipation)

What is this medication?

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.

This medicine may be used for other purposes; ask your health care provider or pharmacist if you have questions.
