Clozapine for self-injurious behavior in individuals with borderline personality disorder.

Prior reports suggest that clozapine can markedly reduce aggression and self-injurious behavior in patients with borderline personality disorder (BPD). We present a series of four patients with BPD and persistent self-injurious behavior treated with clozapine at a state psychiatric hospital. After treatment with clozapine these patients ceased self-injurious behaviors and aggression, and no longer required intensive levels of observation or restrictive procedures. All were successfully discharged from the hospital soon after initiation of clozapine. Clozapine appears to be efficacious in the management of chronic suicidality, self-injurious behaviors and aggression in patients with severe BPD.
