A patient on warfarin has an INR of 2.5 and needs a dental procedure. What do you do?

  1. Proceed with the procedure (with local hemostatic measures)
  2. Postpone until INR normalizes
  3. Stop warfarin first
Show answer and explanation

Correct answer: A. Proceed with the procedure (with local hemostatic measures)

  • A. Correct. An INR within therapeutic range (generally up to ~3.5) allows routine dental procedures/extractions with local hemostatic measures; warfarin should NOT be stopped (thromboembolism risk).
  • B. Incorrect. Postponing is unnecessary at a therapeutic INR.
  • C. Incorrect. Discontinuing anticoagulation risks serious thromboembolic events and is not indicated for most dental procedures.
