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 .

Uses For capecitabine
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. capecitabine 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.
capecitabine is available only with your doctor's prescription.
Before Using capecitabine
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For capecitabine, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to capecitabine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
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.
Studies in women breastfeeding have demonstrated harmful infant effects. An alternative to this medication should be prescribed or you should stop breastfeeding while using capecitabine.
Interactions with Medicines
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary.

Proper Use of capecitabine
Medicines used to treat cancer are very strong and can have many side effects. Before using capecitabine, make sure you understand all the risks and benefits. It is important for you to work closely with your doctor during your treatment.
Take capecitabine exactly as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. To do so may increase the chance of side effects.
capecitabine should come with a patient information leaflet. Read and follow these instructions carefully. Ask your doctor if you have any questions.
Take capecitabine with food or within 30 minutes after you eat.
Swallow the tablet whole with water. Do not cut, crush, break, or chew it. If the tablet must be cut or crushed, it should be done by a pharmacist.
The dose of capecitabine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of capecitabine. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

Precautions While Using capecitabine
It is very important that your doctor check your progress at regular visits to make sure that capecitabine is working properly and to check for unwanted effects.
Your doctor may request that you have a test to determine if your blood is clotting properly, and may preform this test frequently if you are also taking a blood thinner.
Using capecitabine while you are pregnant can harm your unborn baby. Female patients must use effective birth control during treatment and for 6 months after your treatment ends. Male patients with partners of childbearing potential should also use effective contraception during treatment and for 3 months after the last dose. Tell your doctor right away if you think you have become pregnant.
capecitabine may cause heart problems. Check with your doctor right away if you have chest pain that may spread to your arms, jaw, back, or neck, faintness, nausea, swelling in your hands, ankles, or feet, trouble breathing, or unusual sweating.
Check with your doctor right away if any of the following symptoms occur:
- Diarrhea, moderately severe (four to six stools a day more than usual, or during the night).
- Nausea that is severe enough to cause you to eat less than usual.
- Vomiting two or more times in a 24-hour period.
- Pain and redness, swelling, or sores or ulcers in your mouth or on your lips that are severe enough to interfere with eating.
If vomiting occurs less often than mentioned above, or if nausea does not cause you to eat less than usual, it is not necessary for you to stop taking the medicine or to check with your doctor (unless these effects are particularly bothersome). Also, you do not need to stop taking the medicine if diarrhea occurs less often than mentioned above or if the other side effects listed are not severe enough to interfere with eating or other daily activities. However, check with your doctor as soon as possible if they occur.
Serious skin reactions can occur with capecitabine. Check with your doctor right away if you have blistering, peeling, or loose skin, red skin lesions, pain, swelling, or blisters on the palms of your hands or soles of your feet, loss of fingerprints, severe acne or skin rash, sores or ulcers on the skin, or fever or chills while you are using 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. It can also lower the number of platelets, which are necessary for proper blood clotting. If this occurs, there are certain precautions you can take, especially when your blood count is low, to reduce the risk of infection or bleeding:
- If you can, avoid people with infections. Check with your doctor immediately if you think you are getting an infection or if you get a fever or chills, cough or hoarseness, lower back or side pain, or painful or difficult urination.
- Check with your doctor immediately if you notice any unusual bleeding or bruising, black, tarry stools, blood in the urine or stools, or pinpoint red spots on your skin.
- Be careful when using a regular toothbrush, dental floss, or toothpick. Your medical doctor, dentist, or nurse may recommend other ways to clean your teeth and gums. Check with your medical doctor before having any dental work done.
- Do not touch your eyes or the inside of your nose unless you have just washed your hands and have not touched anything else in the meantime.
- Be careful not to cut yourself when you are using sharp objects such as a safety razor or fingernail or toenail cutters.
- Avoid contact sports or other situations where bruising or injury could occur.
