It is also used to prevent malaria[2] but due to high levels of resistance, this use is becoming less common.[3]
It is also used, usually in combination with other drugs, to treat or prevent various infections in livestock.
Mechanism of action
Sulfadoxine competitively inhibits dihydropteroate synthase, interfering with folate synthesis.
