Social phobia, though the third most common psychiatric disorder in th
e United States. has received little systematic attention until recent
ly. Chronic and disabling symptoms usually precede other disorders in
individuals with comorbidity, including alcohol abuse. Though about 80
% of individuals do not seek treatment. controlled trials have demonst
rated efficacy for several medications. of which phenelzine (an irreve
rsible monoamine oxidase inhibitor [MAOI]) is the best studied. The be
nzodiazepines, clonazepam and alprazolam, also hold promise. New rever
sible MAOIs such as moclobemide and brofaromine are under investigatio
n; fluoxetine and other serotonin selective reuptake inhibitors need f
urther controlled study. The benefits of group cognitive-behavioral th
erapy also appear substantial. Issues for future investigation include
long-term outcome. differential therapeutics, diagnostic subtyping, a
nd combination treatments.
