Lactulose Oral Solution is an oral or topical treatment, depending on the product used for constipation where clinically appropriate. It contains Lactulose.

Suitability depends on your symptoms, medical history, current medicines, allergies, previous treatment and pregnancy or breastfeeding considerations where relevant.

How to use

Use Lactulose Oral Solution exactly as directed by your pharmacist, prescriber or the patient information leaflet supplied with the product.

The treatment schedule for constipation is: 15 ml twice daily initially. Do not change the dose, frequency or duration unless advised by a clinician.

Measure each dose with a suitable measuring device rather than a household spoon. Maintain appropriate fluid intake unless a clinician has advised otherwise.

Lactulose can take at least 2 days to work and may cause wind, bloating or diarrhoea. Maintain adequate fluid intake and reduce the dose if stools become too loose.

If symptoms of constipation worsen, do not respond as expected or you develop a serious reaction, stop and seek appropriate clinical advice.

Main Ingredients

Lactulose Oral Solution contains Lactulose as the main active ingredient or treatment component.

The exact formulation, excipients, device components or inactive ingredients can vary by manufacturer and pack supplied.

Always check the patient information leaflet or product instructions supplied with your specific pack, particularly if you have known allergies or intolerances.

Side Effects & Cautions

Bloating, wind, abdominal cramps and diarrhoea can occur, particularly when treatment is started or the dose is too high.

Stop treatment and seek urgent medical help for difficulty breathing, swelling of the face, lips or tongue, collapse or another severe allergic reaction.
