Lactulose: Uses, Side Effects, and Drug Interactions

Brand names: Enulose

# Lactulose: What You Need to Know Lactulose is a medicine used to treat two main problems: constipation and a liver condition called hepatic encephalopathy. For constipation, lactulose works by drawing water into your intestines, which softens your stool and makes it easier to go to the bathroom. For people with liver problems, it helps reduce harmful substances in the body that can affect the brain. Your doctor will tell you how much to take based on why you need it and how your body responds to the medicine. When taking lactulose, there are some important safety points to remember. The most common side effects are gas, bloating, and stomach cramps, especially when you first start taking it. You should drink plenty of water while using this medicine. If you're also taking antibiotics (especially neomycin), tell your doctor right away, because these medicines can interfere with how lactulose works in your body. Always follow your doctor's instructions on how much to take, and don't stop taking it without talking to your doctor first, even if you feel better.
