This medicine contains the active ingredient lactulose which is a synthetic sugar used for the treatment of constipation. It obtains the water from the body and into the colon, which makes the stool softer. This medicine is used for the treatment of occasional constipation (irregular bowel movement and inability to release stool).
It is also used to treat hepatic encephalopathy (a liver disease causing confusion, tremor, decreased level of consciousness including coma). This is also known as a 'hepatic coma'.
Is Lactulose suitable for me?
Lactulose is not suitable for everyone. Do not use it
- if you are allergic to lactulose or other ingredients of this medicine
- if you have a rare problem called 'galactosaemia'

In particular, you must tell the doctor if you:
