The clinical profile of hepatotoxicity induced by tuberculosis drugs varies and the re-introduction of therapy for patients who developed this condition is controversial.5 pediatric cases treated throughout a period of 10 years in the Pediatric Department of Hipolito Unanue National Hospital are presented.2 individuals showed an asymptomatic increase of transaminases, 2 individuals had hepatitis, and 1 individual had acute liver failure. Most patients were female school students. Malnutrition and therapy continuation once the hepatic damage was started were found to be the risk factors.A staged reintroduction scheme for these agents after recovery from hepatitis is proposed.
