Besides warfarin wot can i do to help with my inr it shud be 2.5 -3.5 but over last yr it's been anywhere between 1.4 - 7.2?

Do this:: Try to eat a relatively monotonous diet - especially about the same amount of greens every day. Inform your doctor of any medicine changes (started or stopped) including over the counter meds and herbal preps. Get your value checked often, at least once a week until your INR is remaining between 2.5 and 3.5 several times in a row. Put your meds in a weekly dispenser to confirm you took it daily.
