Comprehensive clinical interaction and dietary monograph for Indinavir (Indinavir).

Generic Active Chemical: Indinavir
Brand Formulations:Crixivan

Kitchen Food, Drink & Dietary Conflicts

Biochemical interactions with common foods, beverages & cooking ingredients
5 Flagged Foods
Official Patient Dietary Instruction (NLM MedlinePlus)

Drink at least 48 ounces (1.5 liters), which is approximately six 8-ounce (240-milliliter) glasses, of water or other liquids every 24 hours. Talk to your doctor about eating grapefruit and drinking grapefruit juice while taking this medication.

CRITICAL

Grapefruit / Pomelo (Citrus paradisi / Citrus maxima)

NutriDive Kitchen Food Biochemical Ontology & openFDA
Bioactive Compound:Furanocoumarins (Bergamottin, 6',7'-Dihydroxybergamottin)
Biological Target:Intestinal Cytochrome P450 3A4 (CYP3A4) & P-glycoprotein
Clinical Mechanism:

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).

Patient Actionable Rule:Completely avoid grapefruit, pomelos, and Seville oranges for the entire duration of therapy. Normal intestinal CYP3A4 enzyme turnover takes up to 72 hours to regenerate after ingestion.
HIGH

Green Tea, Black Tea & Matcha (Tannins & OATP Inhibitors)

NutriDive Kitchen Food Biochemical Ontology & openFDA
Bioactive Compound:Polyphenolic Tannins & Catechins (EGCG)
Biological Target:Ionic Iron Transporters & OATP1A2 / OATP2B1
Clinical Mechanism:

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).

Patient Actionable Rule:Do not take oral iron supplements with tea; drink tea between meals at least 2 hours apart. If taking fexofenadine or nadolol, avoid green tea within 4 hours.
HIGH

Coffee & High-Caffeine Beverages (Espresso, Energy Drinks)

NutriDive Kitchen Food Biochemical Ontology & openFDA
Bioactive Compound:1,3,7-Trimethylxanthine (Caffeine)
Biological Target:Cytochrome P450 1A2 (CYP1A2) & Adenosine A1/A2A Receptors
Clinical Mechanism:

Ciprofloxacin, fluvoxamine, and oral contraceptives inhibit CYP1A2, reducing caffeine clearance by 30-80% and precipitating palpitations, panic, and severe tremors. Caffeine also accelerates gastric motility, impairing bisphosphonate and thyroid absorption.

Patient Actionable Rule:Take thyroid hormones and bisphosphonates with pure plain water only. Moderate or avoid concentrated caffeine during ciprofloxacin therapy.
HIGH

Dairy Milk, Yogurt & Calcium-Enriched Foods

NutriDive Kitchen Food Biochemical Ontology & openFDA
Bioactive Compound:Ionic Calcium (Ca2+) & Casein Micelles
Biological Target:Intestinal Chelation & Luminal Complexation
Clinical Mechanism:

Divalent calcium binds fluoroquinolone (ciprofloxacin) and tetracycline (doxycycline) antibiotics into unabsorbable ring complexes, reducing systemic antibacterial coverage by up to 90% and causing therapy failure.

Patient Actionable Rule:Separate all dairy ingestion from oral antibiotics, bisphosphonates, and thyroid medications by at least 2 to 4 hours.
HIGH

Fresh Orange Juice & Apple Juice (OATP Influx Blockers)

NutriDive Kitchen Food Biochemical Ontology & openFDA
Bioactive Compound:Flavonoid Glycosides (Naringin, Hesperidin)
Biological Target:Organic Anion Transporting Polypeptides (OATP1A2 & OATP2B1)
Clinical Mechanism:

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%.

Patient Actionable Rule:Take fexofenadine (Allegra) and atenolol with plain water only. Avoid drinking fruit juices within 4 hours before or after dosage.
