Warfarin? Warferin is a common misspelling of warfarin.
Warfarin sodium (Coumadin®, Jantoven®) is a prescription medicine often used for preventing blood clots from forming. When used to treat a blood clot, the drug keeps clot formation in check, allowing the body's natural processes to break it down. Warfarin usually comes in tablet form, but is also available as an injection (although this is rarely used). It is important that you talk to your healthcare provider before using this medication if you have high blood pressure, diabetes, or liver disease.
