Carbarsone is an organoarsenic compound used as an antiprotozoal drug for treatment of amebiasis and other infections. 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 histomoniasis (blackhead disease).

Nitarsone is an organoarsenic compound that is used in poultry production as a feed additive to increase weight gain, improve feed efficiency, and prevent histomoniasis (blackhead disease). It is marketed as Histostat by Zoetis.

Difetarsone is an antiprotozoal agent. Various studies have shown it to be particularly effective against Trichuris trichiura, commonly known as the whipworm. Prior to the drugs use in the early 1970s, there were few effective treatments for this infection. It has also been used to treat Entamoeba histolytica infections.
