A member asked:

My inr won't go down it was 9 had vit k went to 1.7 then had 2mg warfarin n it went back to 6.3 could u tell me what's goin on with my inr plz?

Coumadin (warfarin) sensitivity: Many people are very sensitive to coumadin (warfarin). I have one patient who takes 1 mg and that is enough. We joke about having her lick a pill to make her INR increase. Hang in there with your doctor and they will find the right dose.
