Social phobia is a chronic and disabling anxiety disorder. Although its pharmacological treatment has not been extensively studied, recent reports suggest that social phobia may be treated with monoamine oxidase inhibitors, beta-blockers, tricyclic antidepressants, and alprazolam. A recent study has shown that fluoxetine is also effective in social phobia, and preliminary results suggest that the same may apply to other serotonin reuptake inhibitors, too. In this paper we describe the results of citalopram treatment in three patients with social phobia.
