National Library of Medicine's Medical Subject Headings online file (MeSH, 1999)


Oral bulk-forming, lubricant, and stool softener laxatives are indicated prophylactically in patients who should not strain during defecation, such as those with an episiotomy wound, painful thrombosed hemorrhoids, fissures or perianal abbesses, body wall and diaphragmatic hernias, anorectal stenosis, or postmyocardial infarction. /Laxatives; Included in US product labeling/

USP Convention. USPDI-Drug Information for the Health Care Professional. 14th ed. Volume I. Rockville, MD: United States Pharmacopeial Convention, Inc., 1994. (Plus Updates)., p. 1704


Oral laxatives are indicated for the short-term relief of constipation. Oral bulk-forming laxatives, stimulant laxatives, and carbon dioxide-releasing suppositories are indicated to facilitate defecation in geriatric patients with diminished colonic motor response. Oral bulk-forming laxatives and stool softener laxatives are preferred to treat constipation that may occur during pregnancy and postpartum to help re-establish normal bowel function or to avoid straining if hemorrhoids are present. In severe cases of constipation, such as with fecal impaction, mineral oil and stool softener laxatives administered orally or rectally are indicated to soften the impacted feces. To help complete the evacuation of the impacted colon, a rectal stimulant or saline laxative may follow. /Laxatives; Included in US product labeling/

USP Convention. USPDI-Drug Information for the Health Care Professional. 14th ed. Volume I. Rockville, MD: United States Pharmacopeial Convention, Inc., 1994. (Plus Updates)., p. 1704


4.2 Drug Warning

Laxatives should not be given to young children (up to 6 years of age) unless prescribed by a physician. Since children are not usually able to describe their symptoms precisely, proper diagnosis should precede the use of a laxative. This will avoid the complication of an existing condition(e.g., appendicitis) or the appearance of more severe side effects. /Laxatives/

USP Convention. USPDI-Drug Information for the Health Care Professional. 14th ed. Volume I. Rockville, MD: United States Pharmacopeial Convention, Inc., 1994. (Plus Updates)., p. 1705


Side/Adverse Effects: Those indicating need for medical attention: Incidence rare: Allergies, undetermined (skin rash). /Laxatives/

USP Convention. USPDI-Drug Information for the Health Care Professional. 14th ed. Volume I. Rockville, MD: United States Pharmacopeial Convention, Inc., 1994. (Plus Updates)., p. 1707


Side/Adverse Effects: Those indicating need for medical attention only if they continue or are bothersome: Incidence less frequent: Stomach and/or intestinal cramping; throat irritation - with liquid forms. /Laxatives/

USP Convention. USPDI-Drug Information for the Health Care Professional. 14th ed. Volume I. Rockville, MD: United States Pharmacopeial Convention, Inc., 1994. (Plus Updates)., p. 1707


Because concurrent use of the docusate salts may increase the absorption of mineral oil, their concomitant administration is not recommended. /Docusate salts/

Surface-Active Agents

Agents that modify interfacial tension of water; usually substances that have one lipophilic and one hydrophilic group in the molecule; includes soaps, detergents, emulsifiers, dispersing and wetting agents, and several groups of antiseptics.

5.4 Mechanism of Action

In vitro studies suggest that these salts of dioctylsulfosuccinic acid lower the surface tension of the stool to permit water and lipids to enter more readily and thus soften the feces. ... More recent evidence indicates that they may stimulate the secretion of water and electrolytes on contact with the mucosa.
