RT Journal Article SR Electronic T1 Pericardial effusion in patients with schizophrenia: are they on clozapine? JF Emergency Medicine Journal JO Emerg Med J FD BMJ Publishing Group Ltd and the British Association for Accident & Emergency Medicine SP 383 OP 384 DO 10.1136/emj.2007.056879 VO 25 IS 6 A1 P Raju A1 G K Rao A1 G Davis YR 2008 UL http://emj.bmj.com/content/25/6/383.abstract AB Clozapine is used in the treatment of resistant schizophrenia. It is used as a reserve drug mainly because of its adverse effect profile affecting gastrointestinal, haematological and cardiorespiratory systems. Cardiac side effects are uncommon but could be potentially life threatening, hence early recognition and active monitoring are essential to prevent serious cardiac side effects. A case of pericarditis with pericardial effusion is described in a patient who was recently started on clozapine which disappeared within 1 week after discontinuation of clozapine.
