Phenelzine (Nardil, Nardelzine) is a non- selective and irreversible monoamine oxidase inhibitor (MAOI) of the hydrazine class which is used as an antidepressant and anxiolytic. Along with tranylcypromine and isocarboxazid, phenelzine is one of the few non-selective MAOIs still in widespread clinical use. It is typically available in 15 mg tablets and doses usually range from 30–90 mg per day, with 15 mg every day or every other day suggested as a maintenance dose following a successful course of treatment.
