title: Clozapine: a mimicry of phaeochromocytoma.
abstract: OBJECTIVE
  To report a case of clozapine-induced hypertension with raised urinary catecholamines.
  
  
  METHODS
  A 27-year-old man fulfilling DSM-III-R criteria for catatonic schizophrenia was treated with clozapine. He later developed both hypertension and raised urinary catecholamines which mimicked phaeochromocytoma.
  
  
  METHODS
  Clozapine was withdrawn.
  
  
  RESULTS
  Both blood pressure and urinary catecholamines normalised.
  
  
  CONCLUSIONS
  Clozapine may induce sympathetic hyperactivity.
