Xeloda (Capecitabine) is used in combination with other medications to treat breast cancer that has come back after treatment with other medications. It is also used alone to treat breast cancer that has not improved after treatment with other medications. Capecitabine is also used to treat colon or rectal cancer (cancer that begins in the large intestine) that has gotten worse or spread to other parts of the body. It is also used to prevent colon cancer from spreading in people who have had surgery to remove the tumor. Capecitabine is in a class of medications called antimetabolites. It works by stopping or slowing the growth of cancer cells.

Capecitabine comes as a tablet to take by mouth. It is usually taken twice a day (in the morning and in the evening) for 2 weeks, followed by a 1 week break before repeating the next dosage cycle. It is usually taken after a meal (within 30 minutes of breakfast and dinner) and with a glass of water. Your doctor will decide how many times you should repeat this cycle.
