Clonazepam in the treatment of obsessive compulsive disorder associated with panic disorder in one patient

The authors present the case of a 21-year-old man with obsessive compulsive disorder (OCD) complicated by panic disorder, whose OCD and panic symptoms resolved during clonazepam treatment. Prior treatment with an equivalent dose of lorazepam had ameliorated his panic attacks without affecting his obsessions or compulsions. Clonazepam worked with a rapidity and completeness uncharacteristic of more established treatments for OCD.
