Capecitabine is commonly used to treat breast, colorectal, gastric, and pancreatic cancer. It may also be prescribed for other conditions or in combination with intravenous chemotherapy.
Dose and Schedule
Taking Capecitabine as instructed is essential to maximise its effectiveness. Please follow these key points:
- Your dose is based on several factors, including your height, weight, overall health, and diagnosis.
- You should take Capecitabine for 14 consecutive days, twice daily. After completing this, you will have one week off the medication before starting a new cycle.
- You should only take Capecitabine twice daily on the days of your radiation therapy. This means no medication is taken on weekends or public holidays unless you are scheduled for radiation on those days.
- Take Capecitabine twice daily with water, within 30 minutes after a meal, at the same times each day, and at least 10–12 hours apart.
- Swallow Capecitabine tablets whole. Do not crush, cut, or dissolve them. If swallowing is difficult, consult your doctor for alternative options.
- If you miss a dose, do not take an extra dose or double up. Simply take your next dose at the usual time. Record missed doses and inform your doctor during your next appointment.
Drug and Food Interactions
- Warfarin (a blood-thinning medication): Capecitabine interacts with warfarin. Inform your doctor if you are taking it; an alternative blood thinner may be prescribed.
- Other medications: Capecitabine also interacts with phenytoin, allopurinol, and certain other drugs. Inform your doctor about any medications you are taking.
- Herbal remedies: Some herbal medications, including St. John’s Wort, may affect chemotherapy.
Storage and Handling
- Store Capecitabine at room temperature (below 25°C) in a dry place, away from light.
- Keep it out of reach of children and pets.
- Whenever possible, administer Capecitabine to yourself.
- If someone else needs to handle the tablets, they should wear gloves.
- Use a separate daily pill box or reminder for Capecitabine. Do not mix it with other medications. If using a pill box, wash it with soap and water before refilling and wash your hands thoroughly after handling the medication.
- Do not dispose of unused Capecitabine in household trash or flush it down the sink/toilet. Return it to your practice for safe disposal.
- If travelling, store Capecitabine in a sealed plastic bag.
