The pill he is on is called a MAO inhibitor (monoamine oxidase) which inhibits a brain enzyme that metabolizes noradrenalin also called norepinephrine (hormone produced by adrenal glands and neurons that carries messages to other nerves and is part of the fight or flight response and affects blood pressure) and serotonin (hormone that regulates mood, appetite, sleep, regulates pain and causes blood vessels to narrow). MAO inhibitors are used in antidepressant, anti-Parkinson, and anti-Alzheimer drugs. Newer MAO inhibitors are readily reversible in their action and cause less concern about drug-food interactions. Your friend should ask his doctor about some of these newer MAO inhibitors.
The nutrition therapy his doctor probably gave him probably restricts tyramine. The tyramine-free nutrition therapy is necessary because foods high in tyramine combined with Parnate or other MAO inhibitors could cause a sudden constriction of blood vessels with an increase in blood pressure which can result in a stroke. He must follow the nutrition therapy strictly while on this medication. Tryptophan (a protein amino acid) supplements are not recommended either.
He should follow his doctor’s nutrition therapy prescription. The medication may be used for a limited time and if discontinued, the tyramine nutrition therapy should be used an additional 2 weeks after stopping the MAO inhibitor. Here is a list of foods to avoid.
