Concerns about long-term use of the benzodiazepines led many doctors to favor tricyclic antidepressants (amitriptyline, imipramine, and nortriptyline). Although effective in the treatment of some anxiety disorders(but not Social Anxiety Disorder), they can cause significant side effects, including orthostatic hypotension (drop in blood pressure on standing), constipation, urinary retention, dry mouth, and blurry vision.
