Kitchen Food, Drink & Dietary Conflicts
Biochemical interactions with common foods, beverages & cooking ingredientsDo not eat grapefruit or drink grapefruit juice while taking this medication. Talk to your doctor before using potassium-containing salt substitutes while you are taking this medication.
Grapefruit / Pomelo (Citrus paradisi / Citrus maxima)
Destroys enterocyte CYP3A4 enzymes, collapsing first-pass drug metabolism and causing up to 12-fold spikes in bioavailability for oral CYP3A4 substrates (statins, calcium channel blockers, immunosuppressants, PDE5 inhibitors).
Potassium-Enriched Salt Substitutes (Low-Sodium Table Salt)
Provides 500-1400 mg potassium per 1/4 teaspoon. When renal potassium excretion is suppressed by ACE inhibitors, ARBs, or aldosterone antagonists (spironolactone), acute severe hyperkalemia (>6.5 mEq/L) can trigger sudden flaccid paralysis and fatal ventricular fibrillation.
Fresh Orange Juice & Apple Juice (OATP Influx Blockers)
Unlike CYP3A4 inhibitors that increase drug levels, fruit juice bioflavonoids block the enterocyte OATP influx pumps, plummeting absorption of oral fexofenadine (Allegra), ciprofloxacin, and atenolol by 30-70%.
Prescription & OTC Drug Interactions (DDI)
Documented pharmacological conflicts & contraindicated co-prescriptionsDietary Supplements, Herbs & Minerals (DNI)
Interactions with over-the-counter vitamins, minerals, and herbal preparationsPotassium Supplements (Potassium Chloride, Gluconate, Citrate)
Direct renin inhibition suppresses downstream aldosterone secretion, preventing physiological urinary potassium excretion. Exogenous potassium supplements directly provoke dangerous serum hyperkalemia.
St. John's Wort (Hypericum perforatum)
Hyperforin potently activates the Pregnane X Receptor (PXR), inducing hepatic CYP enzymes and intestinal P-gp pumps. This accelerates medication clearance and precipitates therapeutic failure.
