The two most-used treatments for phobic and obsessive-compulsive disorders are exposure and drugs. In exposure therapy, the patient is persuaded to re-enter the phobiaor ritual-evoking situation and to stay there despite the ensuing panic until it starts to subside, which may take 1 h or more. The patient does this repeatedly and systematically, noting outcome in an exposure-homework diary which the clinician reviews. Controlled studies show that such self-exposure treatment (requiring little time from the clinician) has lasting value. Only a minority of cases need additional therapist-aided exposure. Antidepressants are useful adjuvants to exposure in dysphoric phobics and ritualisers. No antidepressant is clearly superior to any other. Relapse on stopping medication is a problem. Neither beta-blockers nor benzodiazepines are yet of proven lasting value for these syndromes. It is too easy to forget that drugs have unpleasant side-effects which are not seen with exposure therapy.
