Can acetaminophen and warfarin be taken together?

Concomitant use of acetaminophen and warfarin can result in a pharmacodynamic interaction leading to a supratherapeutic INR and consequent bleeding. Patients taking warfarin who are at high risk of bleeding require close INR monitoring when starting and stopping courses of acetaminophen.

Can Tylenol affect INR levels?

Acetaminophen was independently associated in a dose-dependent fashion with an INR greater than 6.0. For persons taking acetaminophen 9.1 g/week or more, the odds of an INR greater than 6.0 were increased 10-fold.
