Abstract

The efficacy of specific serotonin reuptake inhibitors (SSRI) in the treatment of obsessive-compulsive disorder (OCD) has been established, but more than 40% of patients continue to have a poor response to SSRI. Low-dose antipsychotic augmentation of SSRI has contributed to the amelioration of symptoms in the treatment of refractory obsessive-compulsive disorder patients. Due to the risk of side effects from traditional antipsychotics, atypical novel antipsychotic augmentation of SSRI may be a good choice in the treatment of refractory obsessive-compulsive disorder. Herein we report our experience with two OCD patients, one with a poor response to fluoxetine 80 mg per day for 3 months, and the other with poor response to fluoxetine 60 mg per day for 3 months. Both OCD patients also proved to have a poor response to paroxetine 60 mg per day for 6 weeks. Neither patient had received any psychotherapy or behavioral therapy. Both patients showed significant improvement in their obsessive-compulsive symptoms as measured by the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), after risperidone 1 mg per day was added to their on-going use of paroxetine 60 mg per day. Within 4 weeks of adding risperidone, the two patients' Y-BOCS scores had decreased by 57% and 53%. This result suggests that risperidone augmentation of SSRI may be a good choice and an effective treatment strategy for refractory OCD.
