Pharmacotherapy for obsessive-compulsive disorder

Background Pharmacotherapy for obsessive-compulsive disorder (OCD) was seldom beneficial before clomipramine, a potent selective serotonin reuptake inhibitor (SSRI), became available. Subsequent progress in pharmacotherapy for OCD has increased the possibility of effective treatment for most sufferers. Method Randomised controlled trials of pharmacotherapy for OCD were reviewed, as well as reports of beneficial pharmacotherapy found in open trials and case reports. Results SSRIs are well-tolerated by patients with OCD, even in large doses. Proserotonergic augmentation is seldom helpful but antipsychotic augmentations seem beneficial for many OCD patients with comorbid ties. Conclusions Potent SSRIs are the pharmacotherapy of choice for OCD, with a more limited role reserved for monoamine oxidase inhibitors. if one SSRI is ineffective, others may be beneficial. Non-drug therapies are also important in OCD: behaviour therapy is frequently helpful but infrequently available and neurosurgery is sometimes helpful when all other treatments have failed.
