Some of the most effective medications for anxiety include benzodiazepines and azapirones, according to About.com. Since many people with an anxiety disorder also have depression, doctors also prescribe antidepressants to some patients.
Benzodiazepines are effective when used to treat symptoms of anxiety such as panic attacks and phobias, explains About.com. Some examples of benzodiazepines include Klonopin, Xanax and Ativan. When considering azapirones, BuSpar is the only brand on the market, as of 2015, and many clinicians report success when used. BuSpar is slow acting, however, so for some patients, a benzodiazepine is a better option. If using antidepressants for treating anxiety, the most common option is Tofranil, but other antidepressants often prescribed include Norpramin, Anafranil and Pamelor.
