  • INR measures the efficacy of warfarin and, for DVT, it needs to be between 2 to 3. INR is very sensitive to diet and other medication changes. Your diet must have changed during the travel resulting in this change.
  • In a situation, the warfarin needs to be held for 2 days and the INR rechecked on the third. And, accordingly, the dose is adjusted.
  • If you are taking this for a single DVT that occurred 2 years ago and you do not have a "hypercoagulable state", then the Warfarin can now be stopped. It is not a medication that needs to be taken indefinitely for this indication
