Generic Name: sterculia
Other Names: karaya gum, Sterculia urens
Drug Class: Laxatives, Other
What is sterculia, and what is it used for?
Sterculia, also known as karaya gum, is a natural dietary fiber extracted from Sterculia urens tree, native to India, and purified for use as a laxative. Sterculia is used to relieve occasional constipation and to maintain regularity of bowel movements. Sterculia is also used as a thickener and emulsifier in foods, denture adhesives, and seals for surgical openings (stomas) created in the intestines to treat certain bowel conditions.
Sterculia is a bulk-forming laxative containing fiber that absorbs water and adds bulk and water to the stools, softening and enabling easy passage of stools through the intestines. The increased bulk can also stimulate peristalsis, the series of gastrointestinal (GI) muscle contractions that move the GI contents. Sterculia is available as granules, over the counter (OTC) in the U.S.

- Swallowing difficulties (dysphagia)
- Fecal impaction
- Symptoms of appendicitis or other conditions that require immediate surgical intervention (acute surgical abdomen)
- Rectal bleeding
- Taking sterculia concurrently with other drugs can reduce the absorption of the other drugs. Allow at least a 2-hour gap between sterculia and other drugs.
- Do not administer to children below 12 years unless directed and supervised by a pediatrician.
