The most commonly prescribed class of antidepressants is selective serotonin reuptake inhibitors (SSRIs). While primarily designed to address depression, SSRIs are also employed in the treatment of anxiety and various other mental health disorders. Typically chosen as the initial approach for depression treatment, SSRIs are preferred due to their lower incidence of side effects compared to other antidepressants. Common side effects associated with SSRIs include sexual dysfunction, difficulty sleeping, and changes in weight.
