Abstract
OBJECTIVE: To report a case of inhibition of the effect of warfarin during treatment with ribavirin.
CASE SUMMARY: A 61-year-old white man received combination treatment with interferon and ribavirin during 1 year for chronic hepatitis C. He was on permanent anticoagulant therapy with warfarin after a previous heart valve replacement. The dose of warfarin had to be increased by approximately 40% to maintain the desired level of anticoagulation.
