A. Hypertension is a serious manifestation of an interaction between phenelzine, a monoamine oxidase inhibitor (MAOI), and tyramine-rich foods like aged cheese. This interaction can lead to a hypertensive crisis, which is a medical emergency. B. Diarrhea is not a typical manifestation of the interaction between phenelzine and tyramine-rich foods. The primary concern is hypertension. C. Bradycardia is not associated with the interaction between phenelzine and tyramine-rich foods.
