A clinical approach to pharmacotherapy for personality disorders

PD diagnosis. Has the patient been properly assessed and diagnosed? While history is the most important basis for diagnosis, the clinician should be familiar with the PDs and DSM-5 criteria. Has the patient been informed of the diagnosis and its implications for treatment?

Patient interest in medication. Is the patient interested in taking medication? Patients with borderline PD are often prescribed medication, but there are sparse data for the other PDs. The patient might have little interest in the PD diagnosis or its treatment.

Comorbidity. Has the patient been assessed for comorbid psychiatric disorders that could interfere with medication use (ie, an SUD) or might be a focus of treatment (eg, MDD)? Patients with PDs typically have significant comorbidity that a thorough evaluation will uncover.

PD symptom dimensions. Has the patient been assessed to determine cognitive or behavioral symptom dimensions of their PD? One or more symptom dimension(s) could be the focus of treatment. Table 2 lists examples of PD symptom dimensions.

Strategies to guide prescribing

Strategies to help guide prescribing include targeting any comorbid disorder(s), targeting important PD symptom dimensions (eg, impulsive aggression), choosing medication based on the similarity of the PD to another disorder known to respond to medication, and targeting the PD itself.
