Dimetridazole is primarily used as an antiprotozoal and antibacterial agent in veterinary medicine. It is effective against a range of infections caused by protozoa and anaerobic bacteria in animals, particularly in poultry and swine. The compound is often administered to control and treat diseases such as histomoniasis in turkeys and swine dysentery. Additionally, it has been utilized as a feed additive to promote growth and improve feed efficiency in livestock. However, its use in food-producing animals has been restricted or banned in many countries due to concerns over potential carcinogenic residues in animal products. In aquaculture, it has been employed to manage parasitic infections in fish, though its application in this sector is also limited due to regulatory constraints.
