Educating the patient about his condition is very important, they need to be given reaasurance that their condition does not make them mentally ill and it is manageable.
An effective behavior therapy for agoraphobia is exposure with response prevention. In this treatment, the patient is, first, exposed to a situation that causes anxiety or panic and then he or she learns to "ride out" the distress until the anxiety or attack passes. With each session, the duration of exposure is gradually increased. For effective functioning of the treatment, it is best if the patient is not taking tranquilizers as they can prevent that experience of anxiety from occuring.
Medication is often used for treating phobias. Antianxiety and antidepressive medications are given to help relieve the symptoms associated with phobias. Some antidepressant medications have been shown to reduce the occurrence of panic attacks. Paroxetine is also shown to be quite effective in treatment. Benzodiazepines are used in treating anticipatory anxiety as well as symptoms of panic attacks.
The treatment focusses on achieving normal functioning of the phobic person. The success of the treatment depends on the severity of the condition.
