Treatment recommendations
When considering pharmacologic management of psychotic symptoms in BPD, aim to limit antipsychotic medications to low dosages because of adverse effects and the limited evidence that escalating dosages—and especially using >1 antipsychotic concurrently—are more effective.18 Educate patients that in BPD medications are, at best, considered adjunctive treatments. Blaming psychotic symptoms on a purely biological process in BPD, not only is harmful because medications are unlikely to significantly or consistently help, but also because they can undermine patient autonomy and reinforce the need for an outside entity (ie, medication) to fix their problems.
When treatment is ineffective and symptoms do not improve, a patient with BPD likely will experience mounting distress. This, in turn, could exacerbate impulsive, suicidal, and self-injurious behaviors. Emphasize psychotherapy, particularly for those whose psychotic symptoms are transient, stress-related, and present during acute crises (Table 2). With evidence-based psychotherapy, BPD patients can become active participants in treatment, coupling developing insight with concrete skills and teachable principles. This leads to increased interpersonal effectiveness and resilience during times of stress. Challenging the patient’s psychotic symptoms as false or “made up” rarely is helpful and usually harmful, leading to the possible severance of the therapeutic alliance.3
Bottom Line
Psychotic symptoms in patients with borderline personality disorder (BPD) could look similar to those in primary psychotic disorders. Factors suggesting BPD include a pattern of worsening psychotic symptoms during stress, long-term symptom instability, lack of delusions, presence of dissociation, and nonresponse to antipsychotics. Although low-dosage antipsychotics could provide some relief of psychotic symptoms in a patient with BPD, they often are not consistently effective and frequently lead to adverse effects. Emphasize evidence-based psychotherapies.
