GPT and Hepatitis: Rifampicin‐induced hepatitis was recorded where alanine aminotransferase activity (ALT) increased to both ≥5 × baseline and ≥5 × upper limit of normal (ULN), or to both ≥3 × baseline and ≥3 × ULN with concurrent elevation in serum bilirubin to ≥2 × baseline and ≥2 × ULN, in addition to a Roussel‐Uclaf Causality Assessment Method score of “probable” or “highly probable” for rifampicin causality.
