What is a key dietary warning associated with MAOIs?

• A. Increase tyramine-rich foods
• B. Avoid tyramine
• C. No dietary restrictions
• D. Take with high-protein meals

Answer: (B)

MAOIs block the enzyme that metabolizes monoamines like tyramine. When someone on an MAOI consumes foods high in tyramine, tyramine isn’t broken down properly and can trigger a large, rapid release of norepinephrine. That surge can dramatically raise blood pressure, causing a hypertensive crisis with symptoms like a sudden pounding headache, sweating, rapid heartbeat, and potential risk of stroke. Because of this danger, the key dietary warning is to avoid tyramine-containing foods. This includes many aged or fermented products (such as some cheeses and cured meats), certain wines and beers, soy sauce, and other preserved foods. Increasing tyramine-rich foods would worsen the risk, while there are indeed dietary restrictions with MAOIs to prevent dangerous interactions.
