Off Label Uses
Hepatic encephalopathy, prevention
Data from a limited number of patients in a randomized, controlled study suggest lactitol may be beneficial in the prevention of recurrent portal systemic encephalopathy in cirrhotic patients with portal-systemic shunt [Riggio 1989].
Based on the American Association for the Study of Liver Disease (AASLD) guidelines for the treatment of hepatic encephalopathy in chronic liver disease, nonabsorbable disaccharides (including lactitol) are not routinely recommended for primary prevention of overt hepatic encephalopathy, except in known high-risk cirrhosis patients. In addition, they are not routinely recommended for prevention of posttransjugular intrahepatic portosystemic shunt hepatic encephalopathy. However, use is recommended as secondary prevention after an initial episode of overt hepatic encephalopathy.
Hepatic encephalopathy, treatment
Data from randomized, double-blind, controlled trials; randomized crossover studies; and meta-analyses support the use of lactitol for the treatment of acute and chronic recurrent portal systemic encephalopathy [Gluud 2016], [Mas 2003], [Morgan 1987a], [Morgan 1987b]. Data from a randomized, controlled study and a randomized, crossover study suggest lactitol may be used in the management of minimal portal systemic encephalopathy to decrease ammonia levels and improve psychometric tests [Morgan 1989], [Salerno 1994].
Based on the AASLD guidelines for the treatment of hepatic encephalopathy in chronic liver disease, nonabsorbable disaccharides (including lactitol) are recommended as treatment for overt hepatic encephalopathy. Lactitol is not recommended for routine treatment of minimal hepatic encephalopathy; however, use may be considered on an individualized basis to help improve quality of life.
Mechanical GI obstruction (known or suspected); galactosemia
Chronic idiopathic constipation: Oral: 20 g once daily; may reduce dose to 10 g once daily for persistent loose stools.
Hepatic encephalopathy, prevention of recurrence after portal-systemic shunt (off-label use): Oral: Initial: 0.5 g/kg/day in 2 divided doses; adjust dose to achieve 2 soft stools per day (Riggio 1989).
Hepatic encephalopathy, treatment (off-label use): Oral: 0.5 g/kg/day in 4 divided doses; adjust dose to achieve 2 to 3 soft stools per day (Morgan 1987a; Morgan 1987b; Vilstrup 2014 [AASLD]). Note: Lower doses of 0.3 g/kg once daily or 0.5 g/kg/day in 2 divided doses may be considered in patients with minimal hepatic encephalopathy (Salerno 1994; Morgan 1989).
Refer to adult dosing.
Multi-dose bottle: Use the measuring cap (bottle top) to measure prescribed dose. Dissolve contents in 4 to 8 ounces of water, juice, or other beverage (eg, coffee, tea, soda).
Unit-dose packets: Dissolve contents of packet(s) in 4 to 8 ounces of water, juice, or other beverage (eg, coffee, tea, soda).
Oral: Administration with meals is preferred; drink entire contents of glass. Administer oral medications at least 2 hours before or 2 hours after lactitol.
Store at 20°C to 25°C (68°F to 77°F); excursions permitted between 15°C to 30°C (59°F to 86°F).
Dichlorphenamide: Laxatives may enhance the hypokalemic effect of Dichlorphenamide. Monitor therapy

Concurrent drug therapy issues:
• Absorption: May reduce the absorption of concomitantly administered oral medications. Administer oral medications at least 2 hours before or 2 hours after lactitol.
Bowel movement patterns.
Lactitol has minimal systemic absorption.
Treatment of constipation in pregnant women is similar to that of nonpregnant patients, and medications may be used when diet and lifestyle modifications are not effective. In general, osmotic laxatives are not initial therapy and should be used with caution and only for short durations in pregnancy due to the risk of electrolyte abnormalities (Body 2016).
