Lamotrigine-Induced Persistent Genital Arousal Disorder and a Potential Treatment.

Persistent Genital Arousal Disorder (PGAD) is a rare disorder characterized by involuntary genital arousal without relief after orgasm or subjective feelings of sexual excitement. There is sparse data for effective treatments of PGAD, which can cause significant distress, anxiety, and depression for patients. We present a case of a patient with major depressive disorder (MDD) and post-traumatic stress disorder (PTSD) who was diagnosed with PGAD shortly after she was started on lamotrigine for mood stabilization. Inpatient psychiatric treatment with increasing doses of sertraline resulted in reduction of her symptoms, suggesting its possible role in PGAD treatment and management.
