Benznidazole is an antiparasitic medication used in the treatment of Chagas disease.[4] While it is highly effective in early disease this decreases in those who have long-term infection.[7] It is the first-line treatment given its moderate side effects compared to nifurtimox.[1] It is taken by mouth.[4]

Side effects are fairly common.[5] They include rash, numbness, fever, muscle pain, loss of appetite, and trouble sleeping.[5][2] Rare side effects include bone marrow suppression which can lead to low blood cell levels.[1][2] It is not recommended during pregnancy or in people with severe liver or kidney disease.[5][7] Benznidazole is in the nitroimidazole family of medication and works by the production of free radicals.[2][3]

Benznidazole came into medical use in 1971.[4] It is on the World Health Organization's List of Essential Medicines.[8] It is not commercially available in the United States, but can be obtained from the Centers of Disease Control.[4] As of 2012 Laboratório Farmacêutico do Estado de Pernambuco, a government run pharmaceutical company in Brazil was the only producer.[9]
