Lamotrigine and aripiprazole have shown efficacy as augmentation agents of serotonin reuptake inhibitors for treatment-resistant obsessive-compulsive disorder (OCD). To date, the efficacy of lamotrigine/aripiprazole augmentation has not been reported in OCD treatment. Herein, we report the case of a 37-year-old male with severe OCD and comorbid depression whose symptoms markedly improved after low-dose lamotrigine/aripiprazole augmentation to clomipramine. Our report suggests that early glutamatergic/antipsychotic augmentation contributes to rapid remission of OCD symptoms.
