Scope and limitations
Evidence limitations

Limitations have not yet been documented. Personal history, exact amount and timing, other medicines, allergies, and local guidance may change the answer.

Medical Analysis
Mechanism

Monoamine oxidase inhibitors (MAOIs) inhibit the enzyme responsible for breaking down tyramine. When tyramine is ingested, it can cause a significant increase in norepinephrine levels, leading to vasoconstriction and an increase in blood pressure. This dangerous interaction can result in hypertensive crisis, which is a medical emergency characterized by a rapid and severe elevation in blood pressure, potentially causing stroke or cardiac complications.

Clinical Impact & Risks

Potential for hypertensive crisis, causing severe headache, chest pain, and risk of stroke.

Management & Recommendations

Do not combine MAOIs with tyramine-rich foods. If accidental ingestion occurs, monitor blood pressure closely and seek medical attention for hypertension management.
