Monoamine oxidase inhibitors (MAOIs)

MAOIs approved to treat depression

The Food and Drug Administration (FDA) has approved these MAOIs to treat depression:

  • Isocarboxazid (Marplan)
  • Phenelzine (Nardil)
  • Selegiline (Emsam)
  • Tranylcypromine (Parnate)

Selegiline is available as a skin (transdermal) patch. Using a patch may cause fewer side effects than MAOIs taken by mouth. If you're using the lowest dose patch, you may not need diet restrictions, but ask your doctor.
