What Lactolax is and what it is used for
Lactolax 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.

What Lactolax is used for

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

Lactolax is 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 Lactolax
Do not take Lactolax if:

You are allergic (hypersensitive) to lactulose or any of the other ingredients of
Lactolax (listed in Section 6).

You have a rare problem called 'galactosaemia'.

You have an intestinal blockage caused by anything else but normal constipation,
digestive perforation or risk of digestive perforation.
Do not take Lactolax if any of the above apply to you. If you are not sure, talk to your doctor
or pharmacist before taking Lactolax.
Warnings and precautions:
Talk to your doctor or pharmacist before taking Lactolax if you suffer from any medical
conditions or illnesses, in particular:





if you suffer from unexplained stomach pains
if you are unable to digest lactose (sugar found in milk)
if you have diabetes

You should not take Lactolax if you suffer from:
• galactose or fructose intolerance
• glucose-galactose malabsorption
• Lapp lactase deficiency
If you have diabetes and are treated for hepatic encephalopathy, your dose of Lactolax will be
higher. This high dose contains a large amount of sugar. Therefore, your anti-diabetic
medicine may need to be adjusted.
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 Lactolax for several days and there is no improvement in your condition
or if your symptoms worsen, please contact your doctor.
Paediatric population
In special circumstances your doctor may prescribe Lactolax for a child, infant or baby. In
these cases your doctor will supervise the treatment carefully. Lactolax should only be given
to infants and smaller children if indicated as it can influence the normal reflexes for passing
stools.
Other medicines and Lactolax
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other
medicines.
Taking Lactolax with food and drink
Lactolax can be taken with or without food. There are no restrictions on what you can eat or
drink.
Pregnancy, breast-feeding and fertility
Talk to your doctor or pharmacist before taking this medicine if you are pregnant, might
become pregnant or are breast-feeding. Lactolax can be used during
pregnancy and when breast-feeding if necessary. No effects on fertility are to be expected.
Driving and using machines
Lactolax has no or negligible influence on your ability to drive safely or use machines.

If you have been told by your doctor that you have an intolerance to some sugars, contact
your doctor before taking this medicine.
