Kitchen Food, Drink & Dietary Conflicts
Biochemical interactions with common foods, beverages & cooking ingredientsDo not eat grapefruit or drink 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).
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%.

Interactions with over-the-counter vitamins, minerals, and herbal preparationsChronotherapy & Meal Administration Protocols
Optimal absorption, meal-timing rules & GI tolerability protocolsWhen neratinib is taken alone to treat breast cancer, it is usually taken with food once daily for one year.
Rationale: Food enhances bioavailability, prevents gastric mucosal irritation, or stabilizes peak-to-trough pharmacokinetic variations.
When neratinib is taken with capecitabine to treat advanced breast cancer or breast cancer that has spread to other parts of the body, it is usually taken once daily with food on days 1 to 21 of a 21-day cycle until your condition worsens or you develop serious side effects.
Rationale: Food enhances bioavailability, prevents gastric mucosal irritation, or stabilizes peak-to-trough pharmacokinetic variations.
