People taking capecitabine along with certain "blood thinners" (anticoagulants such as warfarin or phenprocoumon) may have a higher chance of serious, rarely fatal bleeding. Your risk may be higher because you have cancer, or if you are older than 60 years. Bleeding has occurred during treatment and as long as one month after stopping capecitabine.
If you are using an anticoagulant, blood lab tests (INR/PT) will be closely checked. Tell your doctor right away if you have any signs of bleeding or bruising (such as bloody/black/tarry stools). You should be tested for a DPD enzyme deficiency before you start treatment with capecitabine. Ask your doctor for more details.
How to use Capecitabine
Take this medication by mouth as directed by your doctor, usually 2 times a day; once in the morning and once in the evening. Swallow the tablets whole with a full glass of water (8 ounces/240 milliliters) within 30 minutes after a meal. Do not crush or split the tablets. If you have trouble swallowing the tablets whole, ask your health care professional for advice. Your doctor may direct you to take this medication in a treatment cycle. Carefully follow your doctor's instructions.
The dosage is based on your medical condition, body size, and response to treatment. Do not increase your dose or use this drug more often or for longer than prescribed. Your condition will not improve any faster, and your risk of side effects will increase.
Since this drug can be absorbed through the skin and lungs and may harm an unborn baby, women who are pregnant or who may become pregnant should not handle this medication or breathe the dust from the tablets.
