phenelzine ↔ food

Major Food Interaction

During and within two weeks after treatment with phenelzine, you must not consume any foods or beverages that are high in tyramine content. Doing so can raise your blood pressure to dangerous levels, a condition known as hypertensive crisis. The condition is potentially fatal and may cause symptoms such as severe headache, confusion, blurred vision, problems with speech or balance, nausea, vomiting, chest pain, convulsions, and sudden numbness or weakness (especially on one side of the body). You should seek immediate medical attention if you have any of these symptoms. Foods that are high in tyramine include, but are not limited to, air dried meats; aged or fermented meats; sausage or salami; pickled herring; anchovies; liver; red wine; beer; aged cheeses, including blue, brick, brie, cheddar, parmesan, romano, and swiss; sour cream; sauerkraut; canned figs; raisins; bananas or avocados (particularly if overripe); soy beans; soy sauce; tofu; miso soup; bean curd; fava beans; or yeast extracts (such as Marmite). You should avoid the use of alcohol while being treated with phenelzine, as alcohol may increase some of the nervous system side effects such as dizziness, drowsiness, and difficulty concentrating. Also avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.

High Blood Pressure (Hypertension)

Severe Potential Hazard, Moderate plausibility

monoamine oxidase inhibitors - hypertension/CVD

The use of most monoamine oxidase inhibitors (MAOIs) is contraindicated in patients with diagnosed cardiovascular disease, hypertension, or confirmed or suspected cerebrovascular disorders. These drugs can cause hypertensive crises, which sometimes can be fatal, and are characterized by occipital headache, palpitations, neck stiffness or soreness, nausea, sweating, dilated pupils and photophobia. Intracranial bleeding has been reported in some cases in association with the increase in blood pressure. Normotensive patients receiving therapy with MAOIs need to have monitored their blood pressure frequently to detect any evidence of pressor response and treatment should be discontinued immediately if blood pressure increases or the patient reports symptoms such a headaches or palpitations. Additionally, patients should be advised to avoid foods and drinks with high tyramine content such as cheese, sour cream, beer, liver, bananas and others, as these might trigger an hypertensive crisis.
