Capecitabine (Capecitabine Tablets) — Patient Information (Australia)

Capecitabine is an oral anti-cancer medicine used to treat several types of cancer. It belongs to the fluoropyrimidine group and is taken as tablets by mouth. This page explains how capecitabine works, how it is used, what to expect, and important safety information.

Please note: information below is general and may not match your individual plan. Always follow the instructions given by your treating team and read the Consumer Medicine Information (CMI) supplied with your medicine.

Quick Product Summary

How Capecitabine Works (Mechanism of Action)

Capecitabine is a prodrug, meaning it is converted in the body into the active anticancer substance. After absorption, capecitabine undergoes enzymatic conversion to generate 5-fluorouracil (5-FU) mainly in tumour tissues. The active metabolite interferes with the building blocks required for DNA and RNA.

• Disrupts DNA/RNA formation so cancer cells can’t multiply properly.
• Targets rapidly dividing cells, which include many cancer cells (and some normal cells such as those lining the gut and skin).

This is why side effects such as diarrhoea and hand-foot syndrome (redness, swelling, pain, peeling) can occur—these reflect effects on normal, fast-growing tissues.

Pharmacokinetics (Absorption, Distribution, Metabolism, Elimination)

While individual results vary, capecitabine follows a typical pattern in the body:

• Absorption: After oral dosing, capecitabine is absorbed through the gastrointestinal tract.
• Activation: Conversion to active metabolites occurs in the liver and within tissues, including tumours.
• Distribution: The active metabolites circulate and exert effects on dividing cells.
• Elimination: Metabolites are eliminated primarily via the kidneys (urine).

Because kidney function influences elimination, clinicians may adjust dosing in people with reduced kidney function.

Typical Uses and Indications in Australia

Capecitabine is used for several cancer types, depending on the stage, previous treatments, and your overall health. Your treating team will determine the most suitable regimen. Common uses include:

• Breast cancer (including certain stages or in combination regimens, based on clinical circumstances)
• Colorectal cancer (including metastatic disease, often as part of specific protocols)
• Gastric cancer and other gastrointestinal cancers in selected regimens
• Oesophageal or other related cancers in specific treatment pathways (availability and suitability vary)

Indications and eligibility can depend on clinical guidelines and the specific product’s approved usage in Australia. Always refer to the medicine’s CMI and your specialist’s plan for the exact purpose of your course.

Dosing: How Capecitabine is Usually Taken

Capecitabine is taken in cycles, and the exact schedule depends on the cancer type and regimen. A commonly used approach is:

• Oral doses on “active days” for a set period (often 14 days), followed by a rest period (often 7 days), repeated in cycles.

Doses are usually calculated by body surface area (BSA) and adjusted for treatment tolerability, age, blood counts, kidney function, and side-effect severity.

Important: Follow your exact dose instructions exactly. Your team may modify your dose or pause treatment if you develop certain side effects.

When to take your tablets

• Capecitabine is generally taken after food (with water).
• Try to take doses at similar times each day to maintain consistent drug exposure.
• If your schedule changes (e.g., travel), ask your team for advice before adjusting timing.

Timing Tips: Make Treatment Easier

Many people find it helpful to build routines around meals. Practical strategies include:

• Use meal-based dosing: Take each dose soon after finishing food.
• Set reminders: Use phone alarms or medication organisers.
• Track cycles: Keep a calendar noting active days, rest days, and planned blood tests.
• Keep a diary for symptoms: Note diarrhoea frequency, mouth sores, fever, or skin changes—this helps your team respond quickly.

Food Interactions (What to Eat and Avoid)

Food can influence how capecitabine is tolerated. In general:

• Take after meals: Dosing is typically recommended after food to reduce stomach irritation.
• Stay hydrated: If you experience diarrhoea or reduced appetite, focus on maintaining fluid intake.

There are no “forbidden foods” universally for capecitabine, but individual experiences differ. If you develop nausea, mouth sores, or diarrhoea, your treating team may recommend dietary changes.

Alcohol and Medicine Interactions

Alcohol

Alcohol may worsen common side effects such as fatigue, nausea, and can contribute to dehydration. It may also affect liver function. For these reasons, it is generally best to avoid alcohol or keep it to a minimum unless your clinician approves otherwise.

Common medicine interactions

Capecitabine can interact with other medicines through effects on metabolism, blood counts, and kidney/liver function. Tell your pharmacist or doctor about all medicines you take, including:

• Other chemotherapy or cancer therapies
• Blood thinners (e.g., warfarin) — increased bleeding risk can occur
• Anti-gout medicines (e.g., allopurinol) — may increase toxicity risk
• Phenytoin (for seizures) — possible altered levels
• Folic acid or vitamin supplements — may affect treatment outcomes or toxicity
• Antacids and acid-reducing medicines — some combinations can alter drug handling
• Medicines affecting kidney function (e.g., certain NSAIDs or diuretics) — may influence clearance

Never start, stop, or change doses of other medicines without checking first. Your pharmacist can help identify interaction risks.

Safety Profile: What to Watch For

Capecitabine can cause side effects ranging from mild to serious. Most people experience at least some changes during treatment. The most important safety issues to understand are:

• Bone marrow suppression: lower blood counts may raise infection and bleeding risk.
• Gastrointestinal effects: diarrhoea, nausea, vomiting, abdominal discomfort.
• Hand-foot syndrome: redness, swelling, pain, tingling, or peeling on palms/soles.
• Mouth changes: mouth sores or inflammation.
• Fatigue: common during cancer treatment.

Seek urgent medical help if

• You develop a fever (commonly defined as 38°C or higher) or signs of infection.
• You have severe or persistent diarrhoea, dehydration, dizziness, or reduced urine output.
• You experience severe hand-foot symptoms (painful blistering, inability to carry out daily activities).
• You notice signs of an allergic reaction (swelling of lips/face, breathing difficulty, widespread rash).
• You experience uncontrolled vomiting or cannot keep fluids down.

Your local guidance and threshold for “urgent” can differ. Ask your team what symptoms should trigger immediate contact.

Common side effects

• Diarrhoea
• Nausea, vomiting
• Fatigue
• Loss of appetite
• Abdominal discomfort
• Hand-foot syndrome
• Mouth sores
• Changes in taste
• Low blood counts (may appear on blood tests)

Less common but serious risks

• Significant myelosuppression (severe infection or bleeding risk)
• Severe dehydration from diarrhoea
• Severe skin reactions
• Heart-related symptoms (rare; your team will assess risk factors)
• Kidney or liver function changes (monitoring is typical)

Practical Use Tips (How to Reduce Discomfort and Stay Safe)

1) Prevent and manage diarrhoea early

Diarrhoea can become serious quickly, especially if it leads to dehydration. Contact your treatment team early if you notice changes in bowel habits. Common self-care approaches include:

• Start hydrating promptly (water and electrolyte solutions if recommended).
• Follow your clinician’s plan for anti-diarrhoeal medicines if prescribed.
• Avoid foods that worsen diarrhoea (spicy, high-fat, alcohol).
• Monitor frequency and volume. Record when it starts and how many times you go to the toilet.

2) Protect hands and feet to reduce hand-foot syndrome

• Keep skin moisturised with appropriate creams (ask your pharmacist which products are suitable).
• Avoid friction and heat on palms/soles (hot baths, tight shoes, heavy manual work).
• Wear comfortable footwear with cushioning.
• Report early symptoms such as tingling, redness, or mild pain—early management can prevent worsening.

3) Mouth care

• Brush gently with a soft toothbrush.
• Use recommended mouth rinses and avoid irritants (alcohol-based products if they sting).
• Seek advice if you develop painful ulcers or difficulty eating/drinking.

4) Reduce infection risk from low blood counts

• Report fevers immediately.
• Practice good hand hygiene.
• Avoid close contact with people who are sick.
• Follow guidance about vaccinations (some may need timing adjustments during cancer treatment).

5) Keep appointments and monitoring

Blood tests and clinic reviews help detect side effects early and guide dose adjustments. Do not miss scheduled monitoring even if you feel well.

When Doses May Be Adjusted (Dose Modifications)

If side effects occur, clinicians may adjust your dose, delay treatment, or pause temporarily. Dose adjustment decisions are typically based on:

• Severity of diarrhoea or infections
• Degree of hand-foot syndrome
• Blood test results (white blood cells, neutrophils, platelets, haemoglobin)
• Kidney function and other lab values
• Overall wellbeing and ability to complete the planned cycle

Follow your team’s plan for “next steps” if symptoms arise—this is often called a toxicity management plan.

Alternative Options (Depending on Your Cancer and Stage)

Alternatives vary widely by tumour type, stage, previous treatments, and individual health factors. Examples of other chemotherapy or related medicines (not an exhaustive list) may include:

• Other fluoropyrimidines and related regimens used in gastrointestinal cancers
• Targeted therapies and immunotherapies (where appropriate for tumour markers)
• Combination chemotherapy protocols using different agents

Discuss options with your specialist. Factors such as tumour genetics, prior response, and expected side-effect profiles can influence what’s suitable.
