Phenelzine is an irreversible MAO inhibitor, meaning that the changes that that phenelzine affects in brain chemistry do not return to normal after the treatment is stopped. Though the changes remain in place, the levels of phenelzine are usually depleted in the body after about two to three weeks following the final dose. At this point, it’s safe to eat foods that conflict with Nardil and to begin taking other antidepressants like selective serotonin reuptake inhibitors (SSRIs) and tricyclics.

The mental health side effects of Nardil can include somnolence, lethargy, sedation, anorexia, insomnia, and, in rare cases, mania, hypomania, and psychosis. Severe symptoms of mania and psychosis are more likely to occur when patients have a history of high alcohol consumption, viral infection, liver damage, or are of old age. Phenelzine can also trigger nausea, vomiting, dizziness, dry mouth, blurry vision, weight fluctuation, high or low blood pressure, and sexual dysfunction, among others.

MAO inhibitors like Nardil can lead to a hypertensive crisis when mixed with food or alcohol that contains the nutrient tyramine. Tyramine is a natural byproduct of fermentation and is present in large quantities in many types of alcohol and foods. Foods to be avoided when taking phenelzine include fermented products like cheese and many processed types of meat. Chocolate is also high in tyramine.
