Diuretics

Answer and Explanation

Correct Answer : A,D,E

A. Oral contraceptives: Phenobarbital can decrease the effectiveness of oral contraceptives, increasing the risk of contraceptive failure and unintended pregnancy.
B. Antihistamines: While phenobarbital can induce hepatic enzymes, leading to increased

metabolism of some antihistamines, this interaction is less clinically significant compared to the interactions with oral contraceptives, opioids, and diuretics.
C.   Warfarin: Phenobarbital can induce the metabolism of warfarin, potentially reducing its anticoagulant effects and necessitating closer monitoring of international normalized ratio (INR) levels.
D.   Opioids: Phenobarbital can increase the metabolism of opioids, leading to reduced analgesic effects and potentially causing inadequate pain control.

E.   Diuretics: Phenobarbital can accelerate the metabolism of diuretics, potentially reducing their efficacy and necessitating adjustments in dosage or monitoring of electrolyte levels.

Explanation

A. Egg salad sandwich: Eggs are generally considered safe to consume with MAOIs. There are no significant interactions between egg salad and MAOIs.
B. Pepperoni pizza: Pepperoni contains high levels of tyramine, which can cause a hypertensive crisis when consumed with MAOIs. Therefore, pepperoni pizza should be avoided by patients
taking MAOIs.

C. Pancakes and maple syrup: Pancakes and maple syrup are generally safe choices with MAOIs, as they do not contain high levels of tyramine.
D. Fried eggs over-easy: Like egg salad, fried eggs are generally considered safe to consume with MAOIs. There are no significant interactions between fried eggs and MAOIs.
