Sulfadoxine (also spelled sulphadoxine) is an ultra-long-lasting sulfonamide used in combination with pyrimethamine to treat malaria.[1]
It is also used to prevent malaria[2] but due to high levels of sulphadoxine-pyrimethamine resistance, this use has become less common.[3]
It is also used, usually in combination with other drugs, to treat or prevent various infections in livestock.[citation needed]
