An anxiolytic is a medication or attitude aimed at treating anxiety disorder. The most common are benzodiazepines. They are fast-acting and diminish the physical and emotional effects of anxiety. They must be used carefully, as the molecules can be habit-forming and can even create dependence. Antihistamines or antidepressants can also have certain anxiolytic benefits. Therapy can accompany or replace treatment by anxiolytics when treating anxiety in the long term.
