Fluoxetine

The answer is: B

This patient ate tyramine-rich foods while taking an MAOI and went into hypertensive crisis. Tyramine causes release of stored catecholamines from presynaptic terminals, which can cause hypertension, headache, tachycardia, cardiac arrhythmias, nausea, and stroke. In patients who do not take MAOIs, tyramine is inactivated in the gut by MAO, and patients taking MAOIs must be warned about the dangers of eating tyramine-rich foods.
