Chagas disease is a disease endemic in Latin America, caused by the parasite Trypanosoma cruzi. Benznidazole is the most commonly used drug for the etiological treatment of the disease although its effectiveness varies according to the phase of the same and toxic side effects are frequent. This prospective study describes the side effects of benznidazole treatment of a cohort of 373 chronic patients. Of these 40.2% presented adverse reactions. The most frequent side effect were dermatological reactions 32.4% (121 of 373) followed by digestive intolerance 9.1% (34 of 373). Surprisingly, three cases of migratory arthritis were observed.
