Quetiapine-induced hyperventilation and dyspnea.

Objectives: 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.
