What is Nardil?
Nardil is the brand name for phenelzine, a type of antidepressant known as a monoamine oxidase inhibitor (MAOI). It is primarily used to treat major depressive disorder, especially in patients who have not responded to other antidepressant treatments.
It may also be used in certain cases of anxiety disorders and social phobia under strict medical supervision.
How Nardil Works
Nardil works by inhibiting the enzyme monoamine oxidase (MAO), which breaks down neurotransmitters like:
- Serotonin
- Dopamine
- Norepinephrine
By increasing the levels of these brain chemicals, Nardil helps improve mood, emotional stability, and anxiety control.
Uses of Nardil
Nardil is prescribed for:
- Treatment-resistant depression
- Major depressive disorder (MDD)
- Anxiety disorders
- Social anxiety disorder (off-label use)
- Atypical depression
Dosage Information
Nardil dosage must be carefully managed by a healthcare professional.
- Initial dose: 15 mg three times daily
- Maintenance dose: 45–90 mg per day (divided doses)
- Dosage adjustments are made gradually based on response
⚠️ Never stop or adjust dosage suddenly due to risk of withdrawal or relapse.
