Xeloda (Capecitabine) - Oral


Using Xeloda (capecitabine) with oral coumarin-derivative anticoagulants (e.g., warfarin) at the same time can result in altered coagulation parameters, bleeding, and death. People taking Xeloda with these medications

should be monitored frequently by a healthcare provider for their anticoagulant response. People aged 60 years and older who have cancer are at an increased risk.

What Is Xeloda?

Xeloda (capecitabine) is an oral chemotherapy known as an antimetabolite used to treat certain types of colon cancer, colorectal cancer, and breast cancer. When Xeloda is taken orally, it is processed by the body and changed into chemotherapy called 5-fluorouracil.

It is very important that your doctor check your progress at regular visits to make sure that this medicine 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 this medicine 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.

This medicine 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 this medicine. 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 this medicine.

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.

What Are Reasons I Shouldn’t Take Xeloda?

You should not take this medication if you:

  • Are pregnant or breastfeeding: It is recommended to stop breastfeeding during treatment and for two weeks after the final dose.
  • Have severe kidney disease
  • Are allergic to Xeloda or a chemotherapy agent called 5-fluorouracil (5-FU)

What Other Medications Interact With Xeloda?

Although it does not require complete avoidance, Xeloda should be used cautiously in people who take the blood thinner warfarin, as this combination can cause increased bleeding. Dose adjustment of warfarin may be required.

Another drug that may need to be adjusted if taken along with Xeloda is Dilantin (phenytoin)

The medication Zyloprim (allopurinol) should not be taken with Xeloda as it can decrease the effectiveness of Xeloda.

Be sure to tell your healthcare team about all of your medications, including prescription and over-the-counter products, vitamins, and herbal supplements.

What Medications Are Similar?

A medication similar to Xeloda is another chemotherapy agent called 5-FU. Once digested, Xeloda converts into 5-FU in the body. 5-FU is given through an IV infusion, usually over a period of 48 hours.
