Nardil Food Interactions: An Overview
Nardil® (
phenelzine sulfate) is a prescription medication used to treat
depression. It is part of a group of medications called monoamine oxidase inhibitors (MAOIs). As with other MAOI
antidepressants, there are many dangerous food interactions with Nardil.
Cause of Nardil Food Interactions: The Tyramine Effect
Monoamines are a certain type of chemical in the body that include dopamine, norepinephrine, epinephrine, serotonin,
melatonin, histamine, and several others. Monoamine oxidase is an enzyme that breaks down monoamines. MAOI medications block the action of monoamine oxidase, causing an increase in the level of monoamines in the body. In depression, the level of monoamines can be low, so increasing monoamines usually helps with depression symptoms.
Unfortunately, monoamine oxidase is also responsible for breaking down tyramine, a naturally occurring chemical that affects
blood pressure. MAOI medications keep the body from breaking down tyramine and can lead to extremely high tyramine levels (which can be very dangerous). High levels of tyramine can cause a "hypertensive crisis" (dangerously
high blood pressure).
