Common uses
Xeloda is used alone or with other treatments/medications to treat certain types of cancer (e.g., of the breast, colon, rectum). It works by slowing or stopping cancer cell growth and by decreasing tumor size.
Before using
Tell your doctor if you:
• take a blood thinner such as warfarin (Coumadin). Xeloda may increase the effect of the blood thinner. Your doctor will need to test your blood more often and adjust the dose of your blood thinner if needed.
• take phenytoin. Your doctor will need to test your blood more often and adjust the dose if needed.
• are pregnant.
• have kidney problems.
• have liver problems.
• take the vitamin, folic acid.
Directions
Read the Patient Information Leaflet provided by your pharmacist before you start taking capecitabine and each time you get a refill. If you have any questions regarding the information, consult your doctor or pharmacist.
Take this medication by mouth, usually twice daily in the morning and evening or as directed by your doctor. It is best to take this with a full glass of water (8 ounces or 240 milliliters) within 30 minutes after the end of a meal. Capecitabine is usually taken every day for 2 weeks, then stopped for 1 week. This course of treatment may be repeated as directed by your doctor.
If you take any antacid products that contain aluminum or magnesium, take capecitabine 2 hours before or after taking any antacids because these products may change the way your body absorbs capecitabine.
The dosage is based on your medical condition, body size, and response to therapy. You may be taking a combination of different tablet sizes. Pay close attention to your dose and tablet sizes to avoid over- or under-dosing.
Do not increase your dose or take this medication more often than directed without your doctor's approval. Your condition will not improve any faster, and the risk of serious side effects may increase.
Since this drug can be absorbed through the skin, women who are pregnant or who may become pregnant should not handle this medication.
Cautions
Xeloda Warfarin Interaction: Patients receiving concomitant capecitabine and oral coumarin-derivative anticoagulant therapy should have their anticoagulant response (INR or prothrombin time) monitored frequently in order to adjust the anticoagulant dose accordingly. A clinically important Xeloda-Warfarin drug interaction was demonstrated in a clinical pharmacology trial. Altered coagulation parameters and/or bleeding, including death, have been reported in patients taking Xeloda concomitantly with coumarin-derivative anticoagulants such as warfarin and phenprocoumon. Postmarketing reports have shown clinically significant increases in prothrombin time (PT) and INR in patients who were stabilized on anticoagulants at the time Xeloda was introduced. These events occurred within several days and up to several months after initiating Xeloda therapy and, in a few cases, within 1 month after stopping Xeloda. These events occurred in patients with and without liver metastases. Age greater than 60 and a diagnosis of cancer independently predispose patients to an increased risk of coagulopathy.
