Capecitabine oral

Important Note

The following information is intended to supplement, not substitute for, the expertise and judgment of your physician, pharmacist or other healthcare professional. It should not be construed to indicate that use of the drug is safe, appropriate, or effective for you. Consult your healthcare professional before using this drug.




WARNING: Capecitabine may interact with "blood thinners" (anticoagulants such as warfarin or phenprocoumon) and cause serious bleeding episodes; rarely, deaths have occurred. This increased bleeding risk (increased INR/PT) in some cases has occurred within one month of stopping capecitabine, as well as during treatment. If you are using warfarin, your laboratory tests (INR) will be closely monitored, and you should immediately report any signs of bleeding or bruising, including black stools.


Capecitabine is used to treat cancer (e.g., breast or colorectal). Capecitabine kills cancer cells and shrinks tumors by blocking the process by which the cells divide and are formed (DNA/RNA synthesis).
