Kitchen Food, Drink & Dietary Conflicts
Biochemical interactions with common foods, beverages & cooking ingredientsTalk to your doctor about eating grapefruit and drinking grapefruit juice while 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).
Green Tea, Black Tea & Matcha (Tannins & OATP Inhibitors)
Tannins form insoluble macromolecular iron-tannate precipitates, dropping non-heme iron absorption by up to 80%. Catechins additionally inhibit intestinal OATP uptake transporters, drastically reducing bioavailability of beta-blockers (atenolol) and allergy medications (fexofenadine).
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%.
Alcoholic Beverages (Beer, Wine, Spirits)
Multiplies respiratory depression and profound sedation with opioids and sedatives; blocks hepatic lactate uptake with metformin (lactic acidosis); triggers acute disulfiram-like vomiting and tachycardia with metronidazole; and accelerates dose-dumping in extended-release capsules.
Prescription & OTC Drug Interactions (DDI)
Documented pharmacological conflicts & contraindicated co-prescriptionsDietary Supplements, Herbs & Minerals (DNI)
Interactions with over-the-counter vitamins, minerals, and herbal preparationsChronotherapy & Meal Administration Protocols
Optimal absorption, meal-timing rules & GI tolerability protocolsIt is usually taken once a day with food.
Rationale: Food enhances bioavailability, prevents gastric mucosal irritation, or stabilizes peak-to-trough pharmacokinetic variations.
