1. What this medicine is and what it is used for This medicine contains a laxative called Lactulose. It makes the stool softer and easier to pass, by drawing water into the bowel. It is not absorbed into your body.

Lactulose is used to treat constipation (infrequent bowel movements, hard and dry stools).

Lactulose 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'.

2.    What you need to know before you take this medicine

Do not take this medicine if:

•    You are allergic to lactulose or any of the other ingredients of this medicine (listed in section 6)

•    You have a rare problem called 'galactosaemia' (a severe genetic disorder where you cannot digest galactose)

•    You have a blockage caused by anything else but normal constipation, digestive perforation or risk of digestive perforation.

Do not take this medicine if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking this medicine.

Warnings and precautions

Talk to your doctor or pharmacist before taking this medicine if you suffer from any medical conditions or illnesses, in particular:

■    if you suffer from unexplained tummy ache

•    if you are unable to digest milk sugar (lactose)

•    if you have diabetes

You should not take this medicine if you suffer from:

•    galactose or fructose intolerance

■    lapp lactase deficiency

•    glucose-galactose malabsorption

If you have diabetes and are treated for hepatic encephalopathy, your dose of lactulose will be higher. This high dose contains a large amount of sugar. Therefore, you may need to adjust the dose of your anti-diabetic medicine.

Chronic use of unadjusted dosages (exceeding 2-3 soft stools per day) or misuse can lead to diarrhoea and disturbance of the electrolytes balance. During the treatment with laxatives you should drink sufficient amounts of fluids (approx. 2 litres/day, equal to 6-8 glasses).

If you take this medicine for several days (2 to 3 days) and there is no improvement in your condition or if your symptoms worsen, please contact your doctor.


In special circumstances your doctor may prescribe this medicine for a child, infant or baby. In these cases your doctor will supervise the treatment carefully. This medicine should only be given to infants and smaller children if indicated as it can influence the normal reflexes for passing stools.
