Warning: Increased Risk of Bleeding with Concomitant Use of Vitamin K Antagonists. Altered coagulation parameters and/or bleeding, including death, have been reported in patients taking capecitabine concomitantly with oral vitamin K antagonists, such as warfarin.Clinically significant increases in prothrombin time (PT) and international normalized ratio (INR) have been reported in patients who were on stable doses of a vitamin K antagonist at the time capecitabine was introduced.

These events occurred within several days and up to several months after initiating capecitabine and, in a few cases, within 1 month after stopping capecitabine.

These events occurred in patients with and without liver metastases.Monitor INR more frequently and adjust the dose of the vitamin K antagonist as appropriate.
