For pharmaceutical companies, off-label use of a drug represents a substantial “gray market,” to which the company is unable to sell their product directly, yet may be a significant revenue stream. Some drugs have been used more for off-label purposes than for originally approved indications.1

DSM-IV-TR emphasizes that patients with borderline personality disorder (BPD) show a "instability of interpersonal relationships, self-image, and affects, and marked impulsivity beginning by early adulthood and present in a variety of contexts," and any five out of nine listed criteria must be present for the diagnosis to be made.

Borderline personality disorder is a complex, disabling disorder. The chairperson for the American Psychiatric Association workgroup for the evidence-based practice guideline on its treatment gives an overview of this disorder's etiologies, neurobiology, longitudinal course and recommended treatments. Future directions for both treatments and research are also discussed.
