Answer

Warfarin administration can start on day 1 or 2 of heparin therapy. After two consecutive clotting tests showing a therapeutic International Normalized Ratio (INR) and a minimum of 5 days of heparin therapy, the patient can continue on warfarin alone. In most patients, specialists recommend 6-9 months of initial treatment with warfarin.
