This drug is used by mouth or rectally to treat or prevent complications of liver disease (hepatic encephalopathy). It does not cure the problem, but may help to improve mental status. Lactulose is a colonic acidifier that works by decreasing the amount of ammonia in the blood. It is a man-made sugar solution.
How to use Calulose Solution
If you are taking this medication by mouth for liver disease, take it usually 3-4 times a day or as directed by your doctor. To improve the taste, you may mix it into fruit juice, water, milk, or a soft dessert. The goal is to have 2-3 soft stools each day. Dosage is based on your medical condition and response to therapy (i.e., the number of soft stools each day).
This medication can also be given rectally as an enema for liver disease. Mix the recommended amount of lactulose with 700 milliliters (24 ounces) of water or normal saline. Give the solution into the rectum and keep the liquid inside for 30-60 minutes as directed by your doctor. If you keep the enema inside for less than 30 minutes, repeat the dose unless directed otherwise.
Use this medication regularly in order to get the most benefit from it. Remember to use it at the same time each day.
When this drug is given rectally for liver disease, an improvement in your mental status may occur in as little as 2 hours, but if you are taking this medication by mouth, it may take up to 24 to 48 hours. If you are using this medication for constipation, it may take up to 48 hours to have a bowel movement. Inform your doctor if your condition persists or worsens.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
