In Addition to prescribing Klonopin 1mg for anxiety, doctors may also use it to treat a panic disorder. This disorder involves sudden panic attacks, a fear of having more attacks, as well as anxious feelings about the consequences and changes in behavior associated with attacks. In the treatment of social anxiety disorder, clonazepam may be prescribed in addition to antidepressants, such as selective serotonin reuptake inhibitors (SSRIs).
