DUPHALAC

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'
• if you have a blockage caused by anything else but normal constipation, digestive perforation or risk of digestive perforation

In particular, you must tell the doctor if you:

• suffer from unexplained tummy ache
• are unable to digest milk sugar (lactose intolerant)
• have diabetes 
• are pregnant or breastfeeding 

Lactulose interacts with other medicines. It is most important that you tell the doctor all the medications and herbal supplements that you are currently taking.
