Lactulose
About Lactulose
Lactulose is a solution primarily used to treat chronic or temporary constipation and to manage a brain condition caused by severe liver disease. It helps by softening the stool to make bowel movements easier and by lowering ammonia levels in the blood. This medicine is highly valued in clinical practice for its gentle, predictable action on the digestive system.
For the best results, you should take Lactulose consistently at the same time each day, exactly as directed by your healthcare professional. You can take this oral solution with or without food, and you can easily mix it with water, fruit juice, or milk to improve its sweet taste. Making simple lifestyle adjustments, like eating more fibre and drinking plenty of water, will also support your recovery.
While taking Lactulose, some people may experience mild stomach changes like gas, bloating, or minor stomach rumbling. These effects are usually temporary and improve as your body adjusts, but you must contact your doctor immediately if you experience severe diarrhoea, vomiting, or signs of high fluid loss.
Before starting this medication, talk to your doctor if you have diabetes, as this liquid contains small amounts of natural sugars. Do not take this medicine if you have a bowel obstruction, require a low-galactose diet, or have a known allergy to any of its ingredients.
Certain medicines, such as antacids, can interfere with how Lactulose works, while water pills may increase your risk of mineral imbalances. If you are pregnant, breastfeeding, or managing health conditions as an elderly individual, always consult your doctor to ensure this medicine is appropriate for you.

Patients Concern
Disease/Condition Glossary
Constipation: It refers to infrequent bowel movements. The stools are often dry, painful and hard to pass. Constipation is a medical condition in which the person has fewer than three bowel movements in a week. However, bowel patterns may vary from person to person. Symptoms include bloating, abdominal pain, and feeling as if the bowel movement is incomplete. Constipation occurs when the normal muscle contractions in the large intestine slow down, which causes the incomplete elimination of the bowel from the body. Constipation could be associated with a sudden change of diet, a diet with less fibre, not drinking enough liquids, and lack of exercise.
Hepatic encephalopathy: It is a liver/hepatic disease in which the liver does not remove the toxins from the body, which leads to loss of brain function. Hepatic encephalopathy causes confusion, tremor, decreased consciousness and coma.
