View company portfolio →What Duphalac (Lactulose) is used for
Lactulose is a laxative, a medicine that helps you pass stools (poo). It is a man-made sugar that comes as a sweet syrup or liquid to swallow. Very little of it is absorbed into the body. Instead, it is broken down in the bowel into substances that draw water in, which softens the stools and makes them easier to pass. This type is called an osmotic laxative. In people with severe liver disease, it also helps remove toxins such as ammonia from the blood through the bowel. It can be bought from pharmacies and is also prescribed by doctors.
- Constipation (passing stools less often, or stools that are hard and dry)
- Constipation after surgery, as it is gentler on the gut than some other laxatives
- Hepatic encephalopathy: confusion, shaking, sleepiness or coma caused by severe liver disease, where it helps clear toxins that build up when the liver is failing. This use is under a doctor's care.
Get medical help straight away if
- Call an ambulance or go to the emergency department for signs of a severe allergic reaction: swelling of the lips, mouth, tongue or throat, wheezing or struggling to breathe, a tight throat, skin or lips turning blue, grey or pale, sudden confusion or fainting, or a swollen, blistered or peeling rash.
- Contact a doctor straight away if you have severe diarrhoea or vomiting that goes on, together with muscle cramps or weakness or an uneven heartbeat. These can be signs that the body's salts (sodium, potassium, magnesium) are out of balance.
- US advice (MedlinePlus) is to stop taking it and call your doctor straight away if you get stomach pain or cramps, or vomiting. NHS advice is to speak to a pharmacist or doctor if stomach pain is severe.
- If you have taken too much and have bad diarrhoea or stomach pain, stop taking it and contact a doctor or pharmacist straight away.

From our condition guides, written from WHO, NICE and other opened sources. Your doctor decides if Lactulose is right for you and the dose.
- Anaemia in pregnancy: may help if iron tablets cause constipation, alongside more fibre and fluids
- Constipation: Usually first choice when diet changes are not enough
- Piles (haemorrhoids): Keep stools soft so you do not need to strain, which helps piles heal and stops them coming back
