Antidepressants are most commonly used for treating depression. However, these medications can also be used for other conditions as well. For example, newer antidepressants (such as SSRIs, SNRIs, and NDRIs) have been approved for treating conditions such as panic disorder, bulimia, and social anxiety disorder. General off-label antidepressant uses include the treatment of Tourette syndrome, autism, migraines, and premature ejaculation.
Not all SNRIs are approved for all of the above uses.
NDRIs (norepinephrine and dopamine reuptake inhibitors) have been approved to treat depression and for use as a smoking cessation agent (to help people stop smoking). Currently, there is only one NDRI medication, bupropion (Wellbutrin®, Wellbutrin SR®, Wellbutrin XL®, Zyban®), approved for this use in the United States.
