Lactulose Syrup General Information:

Lactulose is a complex carbohydrate that is derived from lactose. It is not particularly absorbed by the body and reaches the colon intact where it is broken down by bacteria in the large intestine and serves as a remedy for constipation as well as helping prevent hepatic encephalopathy, hepatic precoma and coma, and other mental disorders in patients with cirrhosis by lowering the levels of ammonia in the blood.

How does Lactulose Syrup work?

When bacteria in the colon breaks down the Lactulose sugar, it turns into beneficial acids (lactic acid) that help pull water into the colon via osmotic pressure and soften the stool, this way chronic constipation can be treated. An additional benefit of Lactulose Syrup is that it helps transport ammonia from the blood into the colon in patients suffering from cirrhosis of the liver; it converts it into ammonium ion which is then expelled from the body during laxation. This transport of ammonia and subsequent removal from the body helps alleviate mental changes and confusion developed by people with liver diseases.

When/How is Lactulose Syrup taken/used/applied?

Lactulose Syrup is taken orally and it is recommended to mixed it with water, milk, or fruit juice before taking for better taste. It is important to follow your doctor's recommendation on dosage and length of treatment. Children and elderly patients should take smaller dosages since they have more risks of side effects. It is also recommended to drink plenty of water, at least 8 ounces, with each dose. Lactulose Syrup can be taken for long periods of time and it usually starts having an effect in 24 to 48 hours. To achieve the best results, Lactulose Syrup should be taken along with a high fiber diet.

Side Effects

As with any other drugs, taking Lactulose Syrup can cause side effects. Some of the most common adverse reactions include minor gastrointestinal upsets such as bloating, flatulence, and belching. In addition, taking the Lactulose Syrup with food can prevent cramps and abdominal pain. Other minor reactions that usually go away quickly are diarrhea, nausea, and vomiting. If any of these symptoms persist you should contact your physician. Other responses that need to be immediately addressed are faintness, severe weakness, and severe diarrhea since they are considered to be mayor side effects.

Safety Information:

Lactulose Syrup is not recommended for diabetic patients since the syrup usually contains other sugars such as lactose and galactose and this may cause the patient to experience symptoms of high blood sugar such as excessive thirst or urination. For the same reasons, people who need a galactose free diet or are allergic to lactose should avoid taking the Lactulose Syrup and be sure to consult a physician before doing so. People with asthma and other allergies must be careful when taking Lactulose Syrup since they have an increased risk for adverse reactions and should immediately consult their physician in case they have an allergic reaction such as hives, itching or skin rashes. Lactulose Syrup has an FDA rating of B, the second lowest risk, for women who are pregnant which means that they should contact their doctor before taking it and it is generally not recommended for women who are trying to get pregnant or are breast-feeding. Lactulose Syrup may interact with certain other drugs such as laxatives, neomycin, antibiotics and some diabetic medications. Lactulose Syrup should never be taken at the same time as an antacid.


To treat constipation (Chronulac, Constilac, and Duphalac contain 10g lactulose per 15 ml in which there is less than 1.6 g galactose, less than 1.2 g galactose up to 1.2 g of other sugars) adults should take from 15 to 30 ml daily, you may increase the dose, but it should not exceed 60 ml per day. Dosage should be adjusted so there are two to three soft stools every day.

For initial and rapid laxation, Lactulose Syrup can be taken hourly in doses of 30 to 45 ml, but once laxation is achieved the dosage should be reduced to the daily dose. Alternatively, a rectal balloon catheter can be applied using 300 ml Lactulose diluted in 700 ml water or physiologic saline solution and retained for 30 to 60?minutes, this can be repeated every 4 to 6 h.

For the treatment of Portal-Systemic Encephalopathy (Cephulac, Cholac, and Enulose contain 10g lactulose per 15 ml in which there is less than 1.6 g galactose, less than 1.2 g galactose up to 1.2 g of other sugars) adults should take from 30 to 45 ml syrup 3 to 4 times per day.

In children and infants the doses are different and it is strongly recommended to consult a physician before starting treatment. For older children and adolescents the recommended dose is 40 to 90 ml per day in divided doses to produce 2 to 3 soft stools per day.

For infants, a divided dose of 2.5 to 10 ml per day is recommended to also produce 2 to 3 soft stools per day.
