Chronicctive hepatitis consists of a group of chronic liver diseases with continuous or episodic acute inflammation. Long-incubation serum hepatitis virus (HBAg type B) has been implicated as a major causative factor;1 Wilson disease is another that is considerably less common.2 Cases of drug-induced chronic active hepatitis are rare; laxatives containing oxyphenisatin3,4 and methyldopa (Aldomet)5 are the only known examples. There are only two references in the literature associating propylthiouracil with liver abnormalities6,7; in these cases, however, other possible causes of liver disease were not excluded.
