What Lactugal is and what it is used for

Lactugal contains the active ingredient lactulose. It is a type of sugar that is broken down into
mild acids in the colon (the end part of the intestinal tract). These acids draw water into the
colon and thereby soften the stool and easier to pass. It is not absorbed into your body.
Lactugal is used to treat constipation (infrequent bowl movement, hard and dry stools).
Lactugal is sometimes used in patients with a liver condition called hepatic encephalopathy (a
liver disease causing confusion, tremor, decreased level of consciousness including coma). It
helps prevent dangerous toxins from being absorbed into the blood stream.
