Drug-related liver damage is a liver disease caused by toxic damage or allergic reaction of drugs during treatment, also known as drug-related hepatitis. In recent years, with the introduction of new drugs, the trend of drug-related hepatitis has been increasing year by year. Most of the above symptoms and signs appear 1-4 weeks after drug administration, and biochemical tests, such as elevated bilirubin and alanine aminotransferase (ALT), elevated portal aminotransferase (AST), 60% eosinophils in peripheral blood, positive macrophage or lymphocyte transformation test, and negative serum markers for various viral hepatitis, can assist in the diagnosis.
