Summary
Both drugs are anticoagulants, so using them together adds to the bleeding risk. Edoxaban can also alter INR readings, which makes warfarin control harder to assess during overlap or transition.
What this interaction means in plain words
Edoxaban and Warfarin can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Edoxaban belongs to Cardiovascular; Warfarin belongs to Cardiovascular.
Why it happens
Additive pharmacodynamic anticoagulation through inhibition of factor Xa and of vitamin K-dependent clotting factor synthesis.
What to do
Avoid concurrent use except for planned transitions between agents, following labeled switching instructions. During any overlap, monitor INR (at trough of edoxaban) and watch for bleeding.
