Carbarsone is an organoarsenic compound used as an antiprotozoal drug for treatment of amebiasis and other infections.[1][2][3] It was available for amebiasis in the United States as late as 1991. Thereafter, it remained available as a turkey feed additive for increasing weight gain and controlling blackhead disease.[4][5]

Carbarsone is one of four arsenical animal drugs approved by the U.S. Food and Drug Administration for use in poultry and/or swine, along with nitarsone, arsanilic acid, and roxarsone.[6] In September 2013, the FDA announced that Zoetis and Fleming Laboratories would voluntarily withdraw current roxarsone, arsanilic acid, and carbarsone approvals, leaving only nitarsone approvals in place.[7]
