Capecitabine: What You Need to Know

Capecitabine (brand name Xeloda) is an oral chemotherapy many people use for colorectal and certain breast cancers. The big advantage is you can take it at home instead of getting every dose in clinic. That makes daily life easier, but it also means you must follow rules closely and watch for side effects.

How capecitabine works and when it's used

Capecitabine is a prodrug that turns into 5‑fluorouracil (5‑FU) inside the body, mainly in tumor tissue. Doctors prescribe it as a single drug or with other chemo (for example with oxaliplatin, a combo often called XELOX). Common uses include adjuvant therapy after surgery and treatment for metastatic disease.

Treatment schedules vary. A typical plan is two weeks of pills followed by one week off, repeated every three weeks. Exact dose depends on your body size, other drugs, and your overall health—so always use the dose your oncologist gives you.

Side effects, monitoring and practical tips

The most common problems are hand‑foot syndrome, diarrhea, mouth sores, nausea, and tiredness. Hand‑foot syndrome shows as redness, swelling, or pain on palms and soles. Keep skin moisturized, avoid hot water and tight shoes, and tell your team early—adjusting dose often prevents worse symptoms.

Diarrhea can be serious. Stay hydrated, use anti‑diarrheal meds only if your doctor okays them, and call your clinic for persistent loose stools. Mouth sores are managed with gentle mouth rinses and soft foods.

Capecitabine can affect blood counts and liver tests. Your provider will order regular bloodwork. If you have fever, unexplained bruising, or bleeding, contact them right away.

Watch for chest pain or new shortness of breath. Though rare, capecitabine can cause heart problems. Also, it can interact with other medicines—most notably warfarin (can raise INR) and a few antiviral drugs. Always give your care team a full list of pills and supplements.

Do not take capecitabine if you are pregnant or breastfeeding. Use reliable birth control during treatment and for a time after—your oncology nurse will tell you how long.

Practical tips: take each dose with food or within 30 minutes after a meal to reduce stomach upset. Store pills in the original container at room temperature. Keep a planner or set phone alarms so you don’t miss doses. If you vomit soon after taking a dose, call your clinic for instructions instead of simply re‑dosing.

Questions to ask your doctor: What exact dose and schedule will I follow? Which side effects should I report right away? How will we monitor bloodwork and liver function? Who do I call after hours if something urgent comes up?

Capecitabine lets many people stay at home while receiving effective cancer treatment. Follow the dosing rules, watch for warning signs, and keep communication open with your care team—that's how you stay safer and get the most out of treatment.
