Treatment Name: Lactulose
Lactulose is a Supportive Care Therapy for Constipation
How does lactulose work?
Lactulose is designed to prevent your intestines from absorbing some of the water you drink. When extra water is kept within the intestines, it softens the stool and stimulates the intestines, which produces a bowel movement.
What are lactulose goals of therapy?
Lactulose is taken to relieve occasional constipation. It is commonly taken on an as needed basis with the goal of treating constipation.
Other names: Enulose, Kristalose, Constulose, Generlac
Schedule
How is lactulose taken for constipation?
- Usual starting dose: 1 to 2 tablespoons (15 to 30 mL) oral solution by mouth once daily
Lactulose is commonly taken at home on an as needed basis to treat constipation to maintain normal, regular bowel movements daily or every other day.
Store lactulose at room temperature (68-77°F).
Side Effects
What are the most common side effects from lactulose?
In the prescribing label information (lactulose package insert), the most commonly reported side effects from lactulose are shown here:
Lactulose is not absorbed into the blood stream and generally considered safe when taken by pregnant women for short-term use; however, it should be only used in pregnant women if the potential benefits to the mother outweigh any potential risks to the unborn baby.
Note: The exact percentages of patients that will experience lactulose side effects is unknown because it has been used under widely varying patient populations in a variety of clinical trials.
Monitoring
How often is lactulose monitoring needed?
Labs (blood tests) are usually not necessary to start or continue lactulose therapy.
How often is lactulose imaging needed?
Imaging may be checked if there is concern of a small bowel obstruction (SBO) or blockage. Imaging may include: Abdominal X-ray, or CT scan of the abdomen and pelvis.
How might lacutlose blood test results/imaging affect treatment?
Depending upon the results, your doctor may advise to continue lactulose as planned, add additional laxatives, place you on “bowel rest” (nothing by mouth until the obstruction clears), or switch to an alternative therapy for constipation.

ChemoExperts Tips
What are the most important things to know about lactulose?
- Lactulose solution contains lactose and may increase blood sugar in patients with diabetes
- If you are receiving chemotherapy, do NOT attempt to use an enema or suppository unless you have discussed this with your doctor. Use of enemas or suppositories could cause a tear in the rectum and may lead to a serious infection
- Walking helps to stimulate the bowels to move stool down the intestinal tract. A diet high in fiber (found in fruits, vegetables, and whole grains) also helps to maintain a healthy colon (large intestine)
- It is important to have regular bowel movements, usually once daily or every other day. Otherwise, your small bowel (intestine) may become blocked. Call your doctor if you have not had a bowel movement for 3 days or more, especially if you feel bloated. If you feel pain in your abdomen/belly, feel nauseated, or vomit at any point while constipated, call your doctor immediately
- A pharmacist should ALWAYS review your medication list to ensure that drug interactions are prevented or managed appropriately
