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] In 2015 FDA withdrew the approval of using nitarsone in animal feeds. The ban came into effect at the end of 2015.^[8]
