Anorexia or prolonged fasting: 36 hours or more may cause moderate rise. Pernicious anemia, hemolytic anemias, erythroblastosis fetalis, other neonatal jaundice, hematoma, and following a blood transfusion, especially if several units are given in a short time.

Drugs causing cholestasis and/or hepatocellular damage include diphenylhydantoin, azathioprine, phenothiazines, erythromycin, penicillin, sulfonamides, oral contraceptives, anabolic-androgenic steroids, halothane, aminosalicylic acid, isoniazid, methyldopa, indomethacin, pyrazinamide, and others.
