i have factor five leiden and am on lifetime warfarin. I have been scheduled to have a tooth extracted. My recent inr was 2.7. Do I need to reduce or discontinue my warfarin prior to the extraction? The dentist office said that my inr should be 1.7 or lower.
HIT hanks for posting your query to Chat Doctor.  Yes your Dentist is right. Your INR needs to be less than 1.7 else it may cause bleeding after extraction. You have not mentioned what dose of warfarin you are on ?  I advise you to take half the dose and repeat INR after 4 days. IF It's less than 1.7 get your tooth extracted, but if It's still more than that you can repeat the test after 8 days.  Kindly re-start the previous dose 1 day after extraction.
