What DUPHALAC is used for
DUPHALAC belongs to a group of medicines known as laxatives.
DUPHALAC is used to treat chronic constipation. It can be taken by pregnant women.
It works by increasing the amount of water and stool bulk in the bowel, promoting normal bowel activity.
DUPHALAC can also be used to treat portal-systemic encephalopathy (PSE), also known as hepatic encephalopathy (a disease of the brain that occurs when the liver is not working properly. Symptoms are caused by too much ammonia in the blood). It works by lowering the level of ammonia in the blood.
DUPHALAC can be used where a soft stool is considered of medical benefit (haemorrhoids, anal surgery).
Ask your doctor or pharmacist if you have any questions about why DUPHALAC has been prescribed or recommended for you.
Your doctor or pharmacist may have prescribed or recommended DUPHALAC for another reason.
There is no evidence that DUPHALAC is addictive.

At high doses you may suffer diarrhoea. If this happens, reduce the dose and/or tell your doctor or pharmacist.

nausea
vomiting
These side effects are uncommon.
Very rarely, infants given DUPHALAC may develop dehydration.

Some of these side effects (for example, potassium levels in the blood) can only be found when your doctor orders blood tests.
