A client taking phenelzine for atypical depression is inquiring about food restrictions; which food can they safely eat?

Clients taking phenelzine, which is a monoamine oxidase inhibitor (MAOI), need to be aware of food restrictions due to the risk of hypertensive crises that can be triggered by tyramine, a substance found in various aged, fermented, or matured foods.

Low-fat yogurt is considered safe because it typically contains low levels of tyramine and is a dairy product that does not undergo the same aging process that hard cheeses or certain meats do. This makes it an appropriate choice for someone on phenelzine. Foods like cheddar cheese, aged meat, and fermented products, however, are generally high in tyramine and should be avoided to manage the risks associated with MAOI therapy.

Choosing low-fat yogurt allows the client to enjoy a nutritious option without the dangers of increasing their tyramine intake.
