Background: Several classes of drugs, such as antibiotics, may interact with warfarin to cause an increase in warfarins anticoagulant activity and the clinical relevance of warfarin-antibiotic interactions in older adults is not clear. Objective: The aim of this study was to determine the effect of oral antibiotics, such as amoxicillin, azithromycin, cephalexin, ciprofloxacin, levofloxacin. Warfarin—the most widely used oral anticoagulant worldwide 1 —is commonly prescribed for the treatment and prevention of thromboembolism in patients with deep vein thrombosis, pulmonary embolism, atrial fibrillation and mechanical heart valves. 1-4 Warfarin has a narrow therapeutic range and requires frequent monitoring to avoid potentially life-threatening complications from both under. Antibiotics in the same class have similar effects on INR: Cephalosporins may increase INR by inhibiting production of vitamin K-dependent clotting factors. 6,13; Fluoroquinolones may increase INR by inhibiting warfarin metabolism, displacing warfarin from protein-binding sites, or disturbing intestinal flora that synthesizes vitamin K. 7,1 I haven't heard of any caution about interactions between Warfarin and antibiotics, and I have not taken an antibiotic since I started taking Warfarin 5 years ago.
