Borderline personality disorder (BPD) is a severe mental health condition characterized by pervasive instability in mood, self-image, and interpersonal relationships, significantly impacting individuals' personal, social, and occupational functioning. Current treatment strategies primarily include psychotherapy and pharmacotherapy, but there remains a need for more effective and targeted pharmacological options. This review examines the therapeutic role of lamotrigine in BPD, focusing on its efficacy, safety, mechanisms of action, and practical treatment strategies. A comprehensive review of the existing literature was conducted, including clinical trials, observational studies, and relevant pharmacological data. Key focus areas included lamotrigine's impact on BPD symptoms, pharmacological profile, and comparative effectiveness with other treatments. Lamotrigine has shown promise in managing BPD symptoms, particularly in stabilizing mood and reducing emotional dysregulation and impulsivity. Clinical trials suggest that lamotrigine can effectively address core symptoms of BPD, with a safety profile generally comparable to other treatments. The medication's mechanism of action, which involves modulation of glutamate release and mood stabilization, aligns with the therapeutic goals for BPD. Lamotrigine represents a potential adjunctive treatment for BPD, offering benefits in mood stabilization and symptom management. Integrating psychotherapy and other pharmacological options should be considered within a multimodal treatment approach. Further research is needed to better understand its long-term efficacy and safety and its role in combination therapy.
