[8]For patients who are on anticoagulant therapy, the therapeutic INR ranges between 2.0 to 3.0. INR levels
above 4.9
are considered critical values and increase the risk of bleeding.
What is considered dangerously high INR?
INR
above 8.0
If the INR is greatly above 8.0 (upwards of 10.0 for a patient with no risk factors for falls or haemorrhage), or the patient is elderly and at risk of a fall, 1-2mg of IV phytomenadione may be considered.
What happens if INR is too high?
The higher your PT or INR, the longer your blood takes to clot. An elevated PT or INR means your blood is taking longer to clot than your healthcare provider believes is healthy for you. When your PT or INR is too high, you have
an increased risk of bleeding
.

at greater risk for ischemia than
those who are therapeutic.
Is 2.6 INR good?
The Japanese Circulation Society guideline has recommended prothrombin time-international normalized ratios (PT-INR) of
1.6 – 2.6 for elderly patients
and 2.0 – 3.0 for non-elderly patients, because previous observational studies indicated increased risk of bleeding when the ratio exceeded 2.6.
