food-drug interaction

7 interactions related to food-drug interaction

oranges + ace inhibitors

Oranges and orange juice are rich in potassium, and ACE inhibitors reduce the kidneys' excretion of potassium by suppressing aldosterone. Drinking large daily volumes of orange juice while taking an ACE inhibitor can nudge serum potassium upward. The risk is real but modest for most people; it matters most in those with reduced kidney function, diabetes, or heart failure, or those also taking other potassium-raising medicines or supplements.

potatoes + ace inhibitors

Potatoes are one of the most concentrated dietary sources of potassium, and ACE inhibitors reduce how much potassium the kidneys excrete by lowering aldosterone. Regularly eating large servings of potatoes while taking an ACE inhibitor can nudge serum potassium upward, especially in people with chronic kidney disease, heart failure, or diabetes, or those taking other potassium-raising medicines.

pomelo + simvastatin

Pomelo (Citrus maxima) contains furanocoumarins that inhibit intestinal CYP3A4, the enzyme that breaks down simvastatin during first-pass absorption. With that enzyme suppressed, more simvastatin reaches the bloodstream, raising the risk of muscle-related side effects. This is the same mechanism behind the well-established grapefruit-simvastatin interaction, since pomelo is the parent species of grapefruit and shares its furanocoumarins.

bananas + spironolactone

Bananas are a well-known high-potassium food, and spironolactone is a potassium-sparing diuretic that makes the kidneys hold onto potassium. Eating large amounts of bananas (and other high-potassium foods) while taking spironolactone can push blood potassium too high (hyperkalemia), which in serious cases can disturb the heart's rhythm.

coconut water + spironolactone

Coconut water is naturally high in potassium and is often consumed in large volumes for hydration. Spironolactone is a potassium-sparing diuretic that reduces the kidneys' ability to excrete potassium. Regular high-volume coconut water consumption alongside spironolactone can raise blood potassium into a dangerous range (hyperkalemia), and at least one published case report links excessive coconut water plus spironolactone to life-threatening hyperkalemia.

bananas + lisinopril

Lisinopril is an ACE inhibitor that reduces aldosterone, so the kidneys hold onto more potassium and serum potassium tends to rise. A diet heavy in high-potassium foods like bananas can add to that load. For most people with normal kidneys this is a small, manageable effect; the risk of clinically meaningful hyperkalemia is greater in those with reduced kidney function, diabetes, heart failure, or who also take potassium-sparing diuretics, potassium supplements, or potassium-based salt substitutes.

avocado + ace inhibitors

Avocado is high in potassium, and ACE inhibitors reduce the kidneys' excretion of potassium by lowering aldosterone. Heavy, regular avocado intake combined with an ACE inhibitor — especially alongside other potassium sources or in people with reduced kidney function — can raise serum potassium toward hyperkalemia.
