Antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs), are widely used to treat and prevent a variety of anxiety disorders. Examples of SSRIs that are commonly used to treat chronic anxiety include citalopram (Celexa), escitalopram (Lexapro), fluoxetine (Prozac), paroxetine (Paxil), sertraline (Zoloft). The antidepressants duloxetine (Cymbalta) and venlafaxine (Effexor), SNRIs (serotonin and norepinephrine reuptake inhibitors) act on the brain chemicals serotonin and norepinephrine, and some of the tricyclic antidepressants like imipramine (Tofranil), may also help. Novel antidepressants such as mirtazapine (Remeron) are also prescribed at times.
