TALK TO YOUR DOCTOR ... DON'T PLAY AROUND WITH YOUR COUMADIN OR OTHER BLOOD THINNER DOSAGES YOURSELF!

INR is a normalized ratio of the coagulation time of your blood compared to a standardized sample (to eliminate variations in methods).

Therefore the normal INR is in the range of 0.8 to 1.2

Taking a blood thinner will INCREASE the INR, and yes the amount of blood thinner you take will increase the INR number, but taking less blood thinner will take you back to your normal INR.

Blood thinner dosage is critical if you are in need of it. The blood must be thin enough not to cause thromboses (clots) at locations prone to clotting such as replacement valves or where there's severe narrowing of blood vessels, yet it must not be too thin, because the slightest problem could cause you to bleed excessively either internally or externally as if you had haemophillia. Not very good. Even aspirin can upset your clotting ability (which is why it's recommended for people at risk of cardiac problems). Even at a child's dose daily, some people can bruise exceedingly easily. If you're taking blood thinners you've probably been warned not to take aspirin, for this very reason.

So, if you're suffering for example from cuts that take excessively long to stop bleeding, or excessive bleeding, go see your doctor ... don't adjust your blood thinner dose yourself.
