Which foods should clients taking tranylcypromine avoid?

Clients taking tranylcypromine, a monoamine oxidase inhibitor (MAOI), need to avoid certain foods due to the risk of hypertensive crises, which can occur when tyramine-rich foods are consumed. Tyramine is a naturally occurring compound that can cause blood pressure to spike if not properly metabolized by the body.

Avocado and pickled herring are particularly high in tyramine. Avocados, especially when overripe, contain substantial amounts of tyramine. Pickled herring, as a fermented fish product, is also typically rich in tyramine. This makes these foods especially problematic for individuals taking tranylcypromine, as they may lead to dangerous increases in blood pressure.

The other food options listed are generally lower in tyramine and are not associated with the same risks when consumed by individuals on MAOIs. Therefore, it's essential for those on tranylcypromine to avoid foods such as avocados and pickled herring to maintain their safety and health while undergoing treatment.
