Quetiapine in patients with borderline personality disorder and psychosis: a case series.

Objective Atypical antipsychotics appear to be effective and well tolerated in the treatment of borderline personality disorder. One such agent, quetiapine ("Seroquel"), has a favourable side-effect profile and may be of value in acute and chronic treatment of this disorder. Methods In this case series, 12 outpatients with psychotic disorders meeting ICD-10, DSM-IV and DIB-R criteria for borderline personality disorder were treated with quetiapine monotherapy 300-750 mg/day.
