Things You Must Tell Your Doctor Before Starting Treatment
This section is extremely important for your health and safety. To make sure your treatment works well and to protect you from bad side effects, your doctor needs to know your complete medical history.
Never feel shy or nervous about asking questions or sharing details with your doctor. Honest and open communication helps your medical team choose the safest and best care plan for you.
Make sure to tell your doctor right away before starting Capecitabine if any of the following apply to you:

To get the maximum benefit from your medicine, you must follow your prescription instructions exactly as written by your medical team.
- Swallow your tablets whole with a full glass of water.
- Take your dose within thirty minutes after eating a meal. Never take your pills on an empty stomach.
- Never crush, cut, or chew the tablets, and do not treat them like gum. Swallow them completely intact.
- Keep taking your medicine every single day until your doctor tells you to stop.
Treatment Cycles
Your doctor may explain that you do not take this medicine every single day without a break. Instead, treatment is given in cycles. This means you take the pills for a set number of days, such as two weeks, followed by a rest period of a few days or a week.
Your doctor will design a schedule that fits your unique diagnosis. You must follow this schedule with exact precision. Taking more medicine than prescribed can cause dangerous, life-threatening side effects.
Handling Your Medicine Safely
You should practice safe habits when handling your pills. If possible, wear clean medical gloves when handling or sorting your tablets. Ask your pharmacist or doctor if you have any questions about safe handling at home.
What to Do If You Miss a Dose
If you forget to take your scheduled dose of medicine at the right time, skip that missed dose completely. Do not try to make up for it later.
Take your next dose at the regular scheduled time. Never take two doses at the same time to make up for a missed pill.
Important Safety Precautions During Treatment
While you are taking Capecitabine, you need to pay close attention to how your body feels and protect your health.
Protecting Yourself Against Infections
This medicine can lower your immune system. That means your body has a harder time fighting off germs, and you are more likely to catch infections.
- If you develop a fever, chills, a sore throat, or a cough, contact your doctor right away. Do not try to treat infections by yourself at home.
- Try to stay away from crowds and people who are sick with colds or flus.
Bleeding and Bruising Precautions
Your body may bruise or bleed more easily while taking this treatment.
- Brush your teeth gently. Always use a soft-bristled toothbrush instead of a hard one.
- Watch your skin for unexplained bruises or purple spots. Tell your doctor if your gums bleed or if you get random nosebleeds.
Pregnancy and Breastfeeding Safety
This is a critical rule for both women and men receiving this therapy.
- For women: You must completely avoid getting pregnant while taking this medicine and for at least six months after your last dose.
- For men: You must avoid fathering a child while taking this medicine and for at least three months after your last dose.
- Do not breastfeed while taking Capecitabine and for at least two weeks after your final dose.
Severe Diarrhea, Vomiting, and Skin Reactions
- If you experience severe diarrhea, constant vomiting, or heavy sweating, your body can quickly become dehydrated. Contact your doctor right away for guidance.
- This medicine can sometimes cause serious skin reactions. Seek medical help right away if you notice a red rash with fever, blistering or peeling skin, sores inside your mouth, or swelling of your face and lips.
What Side Effects Might Occur?
Like all prescription medicines, Capecitabine can cause side effects. However, not everyone experiences every side effect. The most important rule is to report any new or worsening problems to your doctor right away.
| Side Effect Category | Symptoms You Must Watch For |

What If You Take Too Much Medicine?

When to Seek Emergency Medical Help
Call emergency services or go to the nearest emergency room right away if you experience chest pain, severe breathing difficulties, sudden severe bleeding, a high fever over 100.4°F (38°C), or severe allergic reactions with swelling of your face and throat.
