What is D-Lac?
D-Lac is a type of sugar. It is broken down in the large intestine into mild acids that draw water into the colon, which helps soften the stools.
D-Lac is used to treat chronic constipation.
D-Lac is sometimes used to treat or prevent certain conditions of the brain that are caused by liver failure, which can lead to confusion, problems with memory or thinking, behavior changes, tremors, feeling irritable, sleep problems, loss of coordination, and loss of consciousness.
D-Lac may also be used for purposes not listed in this medication guide.
D-Lac indications
For the prevention and treatment of portal-systemic encephalopathy, including the stages of hepatic pre-coma and coma.
Controlled studies have shown that D-Lac therapy reduces the blood ammonia levels by 25–50%; this is generally paralleled by an improvement in the patients' mental state and by an improvement in EEG patterns. The clinical response has been observed in about 75% of patients, which is at least as satisfactory as that resulting from neomycin therapy. An increase in patients' protein tolerance is also frequently observed with D-Lac solution therapy. In the treatment of chronic portal-systemic encephalopathy, D-Lac solution has been given for over 2 years in controlled studies.
How should I use D-Lac?
Use D-Lac crystals as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- D-Lac crystals may be mixed with food, fruit juice, water, or milk. It also may be taken dry from a spoon and washed down with water, juice, or milk.
- Drink one or more 8-ounce glasses of liquid with each dose.
- If you miss a dose of D-Lac crystals and you are taking it regularly, take it as soon as possible. If several hours have passed or if it is nearing time for the next dose, do not double the dose to catch up, unless advised by your health care provider. Do not take 2 doses at once.
Ask your health care provider any questions you may have about how to use D-Lac crystals.

D-Lac description
D-Lac syrup, which contains Lactulose with other sugars eg, galactose and lactose, is used in the treatment of constipation and hepatic encephalopathy. D-Lac is a disaccharide, a sugar molecule composed of 2 smaller sugar molecules bonded together, in this case, fructose and galactose. D-Lac is a solid substance that is very soluble in water and has a sweet taste. It is sweeter than lactose but not as sweet as fructose. Chemically, D-Lac is also known as 4-O-β-D-galactopyranosyl-D-fructofuranose. The molecular formula is C12H22O11 with a molecular weight of 342.3 daltons.
D-Lac dosage
D-Lac Dosage
Generic name: D-Lac 10g in 15mL
Dosage form: oral solution
The information at Drugs.com is not a substitute for medical advice. Always consult your doctor or pharmacist.
Oral
Adult
The usual adult oral dosage is 30 to 45 mL (2 to 3 tablespoonfuls, containing 20 g to 30 g of D-Lac Solution) three or four times daily. The dosage may be adjusted every day or two to produce 2 or 3 soft stools daily.
Hourly doses of 30 to 45 mL of D-Lac Solution may be used to induce the rapid laxation indicated in the initial phase of the therapy of portal-systemic encephalopathy. When the laxative effect has been achieved, the dose of D-Lac Solution may then be reduced to the recommended daily dose. Improvement in the patient's condition may occur within 24 hours but may not begin before 48 hours or even later.
Continuous long-term therapy is indicated to lessen the severity and prevent the recurrence of portal-systemic encephalopathy. The dose of D-Lac Solution for this purpose is the same as the recommended daily dose.
Pediatric
Very little information on the use of D-Lac in pediatric patients has been recorded. As with adults, the subjective goal in proper treatment is to produce 2 to 3 soft stools daily. On the basis of information available, the recommended initial daily oral dose in infants is 2.5 to 10 mL in divided doses. For older pediatric patients, the total daily dose is 40 to 90 mL. If the initial dose causes diarrhea, the dose should be reduced immediately. If diarrhea persists, D-Lac Solution should be discontinued.
Rectal
When the adult patient is in the impending coma or coma stage of portal-systemic encephalopathy and the danger of aspiration exists, or when the necessary endoscopic or intubation procedures physically interfere with the administration of the recommended oral doses, D-Lac Solution may be given as a retention enema via a rectal balloon catheter. Cleansing enemas containing soapsuds or other alkaline agents should not be used.
Three hundred mL of D-Lac Solution should be mixed with 700 mL of water or physiologic saline and retained for 30 to 60 minutes. D-Lac Solution enema may be repeated every 4 to 6 hours. If the enema is inadvertently evacuated too promptly, it may be repeated immediately.
The goal of treatment is reversal of the coma stage in order that the patient may be able to take oral medication. Reversal of coma may take place within 2 hours of the first enema in some patients. D-Lac Solution, given orally in the recommended doses, should be started before D-Lac Solution by enema is stopped entirely.

What other drugs will affect D-Lac?
No laxative should be taken within 2 hrs of another medication because the desired effect of the other medication may be reduced.
Antacids: Antacids given concurrently with D-Lac may inhibit the desired D-Lac-induced drop in colonic pH. Therefore, a possible lack of desired effect of treatment should be taken into consideration before such drugs are given concomitantly with D-Lac.
Neomycin: In some situations, neomycin administered together with D-Lac is more effective than either one alone.
Although, theoretically, the elimination of certain colonic bacteria by neomycin and possibly other anti-infective agents may interfere with the desired degradation of D-Lac and thus prevent the acidification of colonic contents. There have been some reports that D-Lac-fermenting bacteria are relatively resistant to neomycin, which may explain why a combination could work in some cases. The status of the D-Lac-treated patients should be closely monitored in the event of concomitant oral antibiotic therapy.

Summary of the Safety Profile: Flatulence may occur during the 1st few days of treatment. As a rule, it disappears after a few days. When dosages higher than instructed are used, abdominal pain and diarrhea may occur. In such cases, the dosage should be decreased.
If high doses (normally only associated with, hepatic encephalopathy or portal systemic encephalopathy) are used for an extended period of time, the patient may experience an electrolyte imbalance due to diarrhea.
