Capecitabine is an anti-cancer ("antineoplastic" or "cytotoxic") chemotherapy drug. Capecitabine is classified as an "antimetabolite." (For more detail, see "How Capecitabine Works" section below).
What Capecitabine Is Used For:
- Colon or rectal cancer
- Metastatic breast cancer
- Esophageal, gastric, hepatobiliary, neuroendocrine, pancreatic, ovarian, fallopian tube, peritoneal or unknown primary cancers (off-label use)
Note: If a drug has been approved for one use, physicians may elect to use this same drug for other problems if they believe it may be helpful.
How Capecitabine Is Given:
- Taken as a pill by mouth.
- Take after food (within 30 minutes of a meal) with water. (Usually taken in a divided dose 12 hours apart).
- Tablets come in 2 sizes; 150mg and 500mg.
- Do not crush, chew or dissolve tablets.
- If you miss a dose, skip the missed dose and go back to your normal time. Do not take 2 doses at the same time or extra doses.
The amount of capecitabine that you will receive depends on many factors, including your height and weight, your general health or other health problems, and the type of cancer or condition being treated. Your doctor will determine your dose and schedule.
Important things to remember about the side effects of capecitabine:

- You may be at risk of infection so try to avoid crowds or people with colds, and report fever or any other signs of infection immediately to you health care provider.
- Wash your hands often.
- To help treat/prevent mouth sores, use a soft toothbrush, and rinse three times a day with 1/2 to 1 teaspoon of baking soda and/or 1/2 to 1 teaspoon of salt mixed with 8 ounces of water.
- Use an electric razor and a soft toothbrush to minimize bleeding.
- Avoid contact sports or activities that could cause injury.
- To reduce nausea, take anti-nausea medications as prescribed by your doctor, and eat small, frequent meals.
- Prevention of hand-foot syndrome. Modification of normal activities of daily living to reduce friction and heat exposure to hands and feet, as much as possible during treatment with capecitabine. (for more information see - Managing side effects: hand foot syndrome).
- Keeps palms of hands and soles of feet moist using emollients such as Aveeno®, Udder cream, Lubriderm® or Bag Balm®.
- Follow regimen of anti-diarrhea medication as prescribed by your health care professional.
- Eat foods that may help reduce diarrhea (see managing side effects - diarrhea).
- Avoid sun exposure. Wear SPF 30 (or higher) sunblock and protective clothing.
- You may experience drowsiness or dizziness; avoid driving or engaging in tasks that require alertness until your response to the drug is known.
- In general, drinking alcoholic beverages should be kept to a minimum or avoided completely. You should discuss this with your doctor.

Monitoring and Testing While Taking Capecitabine:
You will be checked regularly by your doctor while you are taking capecitabine, to monitor side effects and check your response to therapy. Periodic blood work to monitor your complete blood count (CBC) as well as the function of other organs (such as your kidneys and liver) will also be ordered by your doctor.
How Capecitabine Works:
Cancerous tumors are characterized by cell division, which is no longer controlled as it is in normal tissue. "Normal" cells stop dividing when they come into contact with like cells, a mechanism known as contact inhibition. Cancerous cells lose this ability. Cancer cells no longer have the normal checks and balances in place that control and limit cell division. The process of cell division, whether normal or cancerous cells, is through the cell cycle. The cell cycle goes from the resting phase, through active growing phases, and then to mitosis (division).
The ability of chemotherapy to kill cancer cells depends on its ability to halt cell division. Usually, the drugs work by damaging the RNA or DNA that tells the cell how to copy itself in division. If the cells are unable to divide, they die. The faster the cells are dividing, the more likely it is that chemotherapy will kill the cells, causing the tumor to shrink. They also induce cell suicide (self-death or apoptosis).
Chemotherapy drugs that affect cells only when they are dividing are called cell-cycle specific. Chemotherapy drugs that affect cells when they are at rest are called cell-cycle non-specific. The scheduling of chemotherapy is set based on the type of cells, rate at which they divide, and the time at which a given drug is likely to be effective. This is why chemotherapy is typically given in cycles.
Chemotherapy is most effective at killing cells that are rapidly dividing. Unfortunately, chemotherapy does not know the difference between the cancerous cells and the normal cells. The "normal" cells will grow back and be healthy but in the meantime, side effects occur. The "normal" cells most commonly affected by chemotherapy are the blood cells, the cells in the mouth, stomach and bowel, and the hair follicles; resulting in low blood counts, mouth sores, nausea, diarrhea, and/or hair loss. Different drugs may affect different parts of the body.
Capecitabine belongs to the category of chemotherapy called antimetabolites. Antimetabolites are very similar to normal substances within the cell. When the cells incorporate these substances into the cellular metabolism, they are unable to divide. Antimetabolites are cell-cycle specific. They attack cells at very specific phases in the cycle. Antimetabolites are classified according to the substances with which they interfere.
