Effect of Prophylactic Use of Silymarin on Hepatotoxicity Induced by Anti-tuberculosis Drugs (PESOHHERZ)
Tuberculosis is a worldwide common infectious disease and effective first line anti-tuberculosis (TB) drugs were available such as isoniazid, rifampicin, ethambutol, and pyrazinamide. However, anti-TB drugs may induce hepatic injury resulting in discontinuation of anti-TB drugs or changing anti-Tb drug regimen.
Silymarin has been widely studied for the effect on hepatitis and it has been used in hepatology.
Therefore, the investigators hypothesized that prophylactic administration of silymarin with anti-TB drugs may decrease the incidence and severity of hepatotoxicity induced by anti-TB drugs.

|Official Title:||Effect of Prophylactic Use of Silymarin on Hepatotoxicity Induced by Anti-tuberculosis Drugs|
- incidence of hepatotoxicity [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]the presence of hepatotoxicity will be evaluated at 2weeks, 4weeks, and 8weeks after initiation of anti-TB drugs. An interim analysis will be done after enrolling first 300 subjects.
