Patient leaflet - LAEVOLAC 10G/15ML ORAL SOLUTION, LACTULOSE 10 G/15 ML ORAL SOLUTION SACHETS
1. what lactulose oral solution is and what it is used for
Lactulose oral solution 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 oral solution is indicated in adults and in children and adolescents aged 7 to 18 years.
For children below 7 years, other dosage forms are available.
Lactulose oral solution is used to treat the symptoms of constipation.
You must talk to a doctor if you do not feel better or if you feel worse after 3 days.
2. what you need to know before you take lactulose oral solution
Do not take Lactulose oral solution:
- if you are allergic to lactulose or any of the other ingredients of this medicine (listed in section 6).
- if you suffer from galactosaemia (a severe genetic disorder where you cannot digest galactose), acute inflammatory bowel disease (like Crohn's disease or ulcerative colitis) blockage in your bowel (apart from normal constipation), digestive perforation or risk of digestive perforation, or unexplained abdominal pain.
Warnings and precautions
Talk to your doctor or pharmacist before taking Lactulose oral solution.
Please tell your doctor before taking Lactulose oral solution if you suffer from gastro-cardiac syndrome (Roemheld syndrome).
If you have symptoms like excess gas in your bowels or bloating after using it, stop the treatment and consult your doctor.
In these cases your doctor will supervise the treatment carefully.
Long-term use of unadjusted dosages (exceeding 2–3 soft stools per day) or misuse can lead to diarrhoea and disturbance of the electrolyte balance.
If you are an elderly patient or a patient in bad general condition and take lactulose for a more than 6 months period, your doctor will regularly check your blood electrolytes.
During the treatment with laxatives you should drink sufficient amounts of fluids (approx. 2 litres per day, equal to 6–8 glasses).
Children and adolescents
Lactulose oral solution should not normally be given to infants and smaller children as it can disturb the normal reflexes for passing stools.
In special circumstances your doctor may prescribe Lactulose oral solution for a child, infant or baby. In these cases your doctor will supervise the treatment carefully.
Other medicines and Lactulose oral solution
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicine.
Lactulose may increase the loss of potassium caused by other drugs (e.g. thiazides, steroids and amphothericin B). Use of cardiac glycosides (e.g. digoxin) along with Lactulose can increase the effect of the glycosides by decreasing potassium in the blood.
With increasing dosage a decrease of pH-value in the colon is found. Therefore drugs which are released in the colon pH-dependently (e.g. 5-ASA) can be inactivated.
Lactulose oral solution with food and drink
Lactulose oral solution can be taken with or without food. There are no restrictions on what you can eat or drink.

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
