Remission of treatment-resistant obsessive-compulsive disorder with 600 milligrams of fluvoxamine daily: a case report

Abstract

First-line drugs for obsessive-compulsive disorder (OCD) pharmacotherapy are selective serotonin reuptake inhibitors (SSRI). The medication must be continued for at least 12 weeks at an effective dosage to find the most effective SSRI. For treatment, the drug dose should be titrated to the highest tolerated dose. The manufacturer's recommended maximum dose of fluvoxamine is 300 mg per day. We reported remission after about 1 month of 600 mg (high dose) fluvoxamine, which was tolerated by a patient with OCD. The patient continued at this dose for 3 months and remained in remission.
