Bismuth subgallate

What is Bismuth subgallate?

Bismuth subgallate, with a chemical formula C7H5BiO6, is commonly used to treat malodor by deodorizing flatulence and stools. In the United States it is the active ingredient in Devrom (internal deodorant), an over-the-counter FDA-approved medicine. Also, it has been used to treat Helicobacter pylori infection and is used in wound therapy. As an internal deodorant, it is commonly used by individuals who have had ostomy surgery, bariatric surgery, fecal incontinence, and irritable bowel syndrome.

It can cause darkening of the tongue and stools, which is temporary and harmless. In 1974, a reversible encephalopathy was noted and examined in four colon cancer patients taking bismuth subgallate after abdominoperineal resection.

Also, a double blind study in 1974 reported its effectiveness as a flatulence/stool deodorant in ileostomy patients.
