[Drug-induced active hepatitis (author's transl)].

Drug-induced active hepatitis is rare. The three main drugs incriminated are oxyphenisatine, alphamethyldopa and isoniazid. Despite the histological appearance suggestive of chronic active hepatitis, such forms of hepatitis, and in particular those due to alphamethyldopa and isonizid, follow an acute rather than a chronic course. The course is usually rapidly favourable when the responsible drug is stopped, provided the histological lesions are not those of multilobar necrosis or cirrhosis.
