title: Quetiapine-induced hyperventilation and dyspnea.
abstract: OBJECTIVE
  Quetiapine is an atypical antipsychotic with favorable properties in the treatment of bipolar disorder, but it has recently been associated with respiratory dysfunction.
  
  
  METHODS
  In this case report, we describe a patient who developed quetiapine-induced hyperventilation and dyspnea after being treated with quetiapine.
  
  
  RESULTS
  To our knowledge, this is the first case presented with quetiapine-induced hyperventilation in a patient with bipolar disorder.
  
  
  CONCLUSIONS
  We recommend a quick reduction of the quetiapine dosage and a change to an alternative antipsychotic for patients treated with quetiapine, who report such respiratory symptoms without a somatic cause for the symptoms.
