Citalopram (Celexa), escitalopram (Lexapro), fluoxetine (Prozac), paroxetine (Paxil), and sertraline are examples of SSRIs that are routinely used to treat persistent anxiety (Zoloft). The most common treatment for panic attacks is the medication benzodiazepines, which include alprazolam (Xanax) and clonazepam (Klonopin). Long-term use of these medications may be necessary to achieve relief from symptoms.
