Xeloda (Generic Capecitabine) Overview
Capecitabine is a chemotherapy medication used to treat advanced colorectal cancer, metastatic breast cancer, and gastric cancer. It belongs to a class of drugs called antimetabolites, which work by interfering with cancer cell growth and division. Unlike some chemotherapy drugs given by injection, capecitabine is an oral medication you take by mouth, making it convenient for at-home treatment.
The drug works through a clever mechanism: your body converts capecitabine into 5-fluorouracil (5-FU), an active chemotherapy agent that targets rapidly dividing cancer cells. This conversion happens primarily in tumor tissues, which may help protect some healthy cells. Capecitabine is often used alone or combined with other cancer treatments depending on your specific diagnosis and treatment plan.

Side Effects
Capecitabine can cause various side effects ranging from mild to severe. Most people tolerate the medication, but side effects are common because chemotherapy drugs affect both cancer cells and some healthy cells. Your doctor will monitor you closely and may adjust your dose if side effects become difficult to manage.
Common Side Effects
Hand-foot syndrome: Redness, swelling, pain, and peeling of the palms and soles; usually develops 2–3 weeks after starting treatment
Nausea and vomiting: Feeling sick to your stomach or actually vomiting; usually managed with anti-nausea medications
Diarrhea: Loose or watery stools that may be severe; staying hydrated is important
Fatigue: Extreme tiredness and lack of energy that affects daily activities
Loss of appetite: Decreased desire to eat, which can affect nutrition and energy levels
Mouth sores: Painful ulcers inside the mouth that make eating and drinking uncomfortable
Serious Side Effects
Severe diarrhea and dehydration: Life-threatening fluid loss requiring immediate medical attention and possible hospitalization
Hand-foot skin reaction (Grade 3 or higher): Severe blistering, peeling, and pain that prevents normal hand and foot function
Bone marrow suppression: Low blood cell counts leading to increased infection risk, easy bruising, or severe anemia
Heart problems: Chest pain, shortness of breath, or irregular heartbeat suggesting heart damage (cardiotoxicity)
Severe allergic reaction: Difficulty breathing, swelling of face or throat, or severe rash requiring emergency care
When to Seek Medical Attention
Contact your doctor immediately if you experience severe diarrhea lasting more than a few hours, inability to keep food or fluids down, signs of infection (fever over 101°F), unusual bleeding or bruising, severe hand-foot syndrome that interferes with daily activities, chest pain, or shortness of breath. These symptoms may indicate serious side effects requiring treatment adjustments or medical intervention.
Do not wait for your next scheduled appointment if you develop any of these warning signs. Capecitabine requires close monitoring, and your doctor needs to know about significant changes in how you're feeling.

Important: Take capecitabine exactly as prescribed by your doctor—do not skip doses or stop treatment without approval.

Never stop capecitabine suddenly, as your doctor needs to monitor your cancer response and adjust treatment as needed. Store tablets at room temperature away from moisture and heat.
Drug Interactions
Capecitabine can interact with several medications and substances, potentially reducing its effectiveness or increasing side effects. Always inform your doctor about all medications, supplements, and herbal products you take. Your healthcare team will review your complete medication list before starting capecitabine.
Warfarin and Other Blood Thinners
Capecitabine may increase the effects of blood-thinning medications like warfarin, raising your risk of bleeding. Your doctor may need to check your blood clotting levels (INR) more frequently and adjust your blood thinner dose.
Phenytoin (Dilantin)
This seizure medication may have reduced effectiveness when taken with capecitabine, potentially leading to breakthrough seizures. Your doctor may need to monitor seizure control more closely and adjust the phenytoin dose.
Leucovorin (Folinic Acid)
Leucovorin is sometimes intentionally combined with capecitabine to enhance its cancer-fighting effects. However, this combination requires careful monitoring for increased toxicity and side effects.
Certain Antacids and H2 Blockers
Medications like cimetidine that reduce stomach acid may decrease capecitabine absorption. Take capecitabine at least two hours apart from these medications when possible.
Methotrexate
Using capecitabine with methotrexate increases the risk of serious bone marrow suppression and other chemotherapy-related toxicities. Your doctor will carefully monitor blood counts if both drugs are necessary.
