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.
