Patients receiving concomitant capecitabine and oral coumarin-derivative anticoagulant therapy should be monitored frequently for anticoagulant response (INR or prothrombin time) and the anticoagulant dose should be adjusted accordingly. Altered coagulation parameters and bleeding, including fatal cases, have been reported in patients taking capecitabine concomitantly with coumarin-derivative anticoagulants such as warfarin or phenprocoumon. These events occurred in patients with and without liver metastases and within several days to several months after initiating capecitabine therapy; however, in a few cases the events occurred within 1 month of discontinuation. Age greater than 60 years and a diagnosis of cancer independently predispose patients to an increased risk of coagulopathy .
Capecitabine is used to help treat patients with Dukes' C colon cancer (colon cancer that has spread to lymph nodes in the area close to the colon), after having surgery. This medicine is also used to treat metastatic colorectal cancer (cancer of the colon or rectum that has spread to other parts of the body).
Capecitabine is also used together with docetaxel to treat metastatic breast cancer (breast cancer that has spread to other parts of the body) in patients who have received other medicines (eg, paclitaxel) but did not worked well, or in patients who cannot receive cancer medicines anymore.
Capecitabine belongs to the group of medicines called antineoplastics (cancer medicines). It interferes with the growth of cancer cells, which are eventually destroyed by the body. Since the growth of normal cells may also be affected by the medicine, other side effects may also occur. Some of these may be serious and must be reported to your doctor.

Appropriate studies have not been performed on the relationship of age to the effects of capecitabine in the pediatric population. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of capecitabine in the elderly. However, elderly patients are more likely to have unwanted side effects (eg, severe diarrhea, nausea or vomiting, hand-and-foot syndrome) or age-related kidney or liver problems, which may require caution and an adjustment in the dose for patients receiving capecitabine.

While you are being treated with capecitabine, and after you stop treatment with it, do not have any immunizations (vaccines) without your doctor's approval. Capecitabine may lower your body's resistance and the vaccine may not work as well or you might get the infection the vaccine is meant to prevent. In addition, you should not be around other persons living in your household who receive live virus vaccines because there is a chance they could pass the virus on to you. Some examples of live vaccines include measles, mumps, influenza (nasal flu vaccine), poliovirus (oral form), rotavirus, and rubella. Do not get close to them and do not stay in the same room with them for very long. If you have questions about this, talk to your doctor.
Capecitabine can temporarily lower the number of white blood cells in your blood, increasing the chance of getting an infection.
