Leflunomide and warfarin interaction: case report and review of the literature.

A 61-year-old Caucasian woman receiving long-term anticoagulation with warfarin for recurrent thromboembolism and atrial fibrillation was found to have an elevated international normalized ratio (INR) after she started leflunomide therapy for rheumatoid arthritis. Her INR had been stable for 4 months before this event. The patient required an overall decrease of 22% in her weekly warfarin dose to maintain a therapeutic INR within the goal range of 2.

Enhanced antithrombotic effect of warfarin associated with low-dose alcohol consumption.

A 58-year-old Caucasian man was receiving long-term anticoagulation with warfarin for the prevention of ischemic stroke; his international normalized ratio (INR) had been stable. His INR increased when he began consistent, low-dose beer consumption for its perceived cardiovascular protection. After he stopped drinking the alcohol, his anticoagulation control improved and returned to previous levels.
