Lactulose
Summary
Lactulose is used to treat constipation, which is difficulty in passing stools, and hepatic encephalopathy, which is a brain disorder caused by liver disease. It helps relieve constipation by softening stools and improves mental clarity in hepatic encephalopathy by reducing ammonia levels in the blood.
Lactulose works by drawing water into the bowel, which softens stools and makes them easier to pass. For hepatic encephalopathy, it reduces ammonia levels in the blood, which helps improve mental clarity. This dual action makes it effective for both constipation and liver-related brain disorders.
Lactulose is usually taken orally, which means by mouth, once or twice daily. The typical starting dose for adults is 15 to 30 milliliters per day, with a maximum of 60 milliliters. It can be taken with or without food and mixed with water or juice if needed.
Common side effects of Lactulose include bloating, which is a feeling of fullness in the abdomen, gas, and diarrhea, which is frequent, loose stools. These effects are usually mild and occur in more than 10% of people taking the medication.
Lactulose should not be used by people allergic to it or on a low-galactose diet, which is a diet low in a type of sugar. Caution is needed for those with diabetes, as it can affect blood sugar levels. Always consult your doctor before starting Lactulose.
