This case involves a 26-year-old male patient with bipolar disorder and severe depression who was prescribed the antipsychotic aripipiprazole. This patient had a family history of bipolar disorder and alcoholism. While taking the antipsychotic medication, the patient experienced a host of compulsive behaviors, specifically pathological gambling and hypersexuality. The patient accrued significant debt from his compulsive gambling, which he asserted was a direct result of his medication use. An expert in pharmacology was sought to address the use of this specific medication, its mechanism of action, and its link to compulsive behavior.
