What are warfarin and heparin?

ANSWER

Both are anticoagulant medications, or "blood thinners," that help stop your blood from thickening (clotting.) Natural clots help seal wounds on the inside and outside of your body. But unnecessary clots can cause problems.

Blood thinners don’t really thin your blood. They just interrupt your body’s natural clotting process. Warfarin and heparin act on different parts of this process.
