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

Alcoholic Beverages (Beer, Wine, Spirits)
