Tyramine is only the visible tip.
Why are MAOIs prescribed so rarely today? Fear of the “cheese reaction” is often cited. But below the surface, we discover that the attention a cause receives and its real causal weight move in opposite directions: the real forces that sideline this treatment class are the deepest — and the least discussed.
The foundation is ethical, not pharmacological
The pharmacology of MAOIs is, in reality, predictable and manageable: the most serious interactions chiefly involve two known mechanisms (serotonin toxicity and a hypertensive surge), pharmacokinetic interactions are generally of limited importance at usual doses, and the diet is simpler than historical lists suggested.
What sidelines the class is therefore not an irreducible danger but a moral asymmetry: the harm of a hypertensive crisis is named, dated and attributable; the harm of treatment-resistant depression left without an option remains diffuse, statistical and invisible. Omission bias makes non-treatment look “safer” than it is. Tyramine becomes a rationalising symbol for a retreat driven elsewhere.
