Doxifluridine
About Doxifluridine
Doxifluridine is a prescription medication used to treat several types of cancers, including stomach, colorectal, breast, and lung cancers. Its primary medical purpose is to slow down or halt the growth of abnormal cancer cells in the body.
For this medication to work effectively, it must be taken consistently and exactly at the times prescribed by your specialist. It is typically taken with water after your meals to help protect your digestive system. To support your treatment, maintaining a balanced diet and staying well-hydrated are highly recommended.
While taking Doxifluridine, some people may experience mild side effects like a temporary loss of appetite or slight nausea. However, if you experience more severe reactions, such as persistent vomiting, severe watery stools, or painful mouth sores, you must contact your doctor immediately.
Talk to your doctor before starting this medication if you have a history of kidney disease or liver damage. Do not take this if you are pregnant, planning to become pregnant, breastfeeding, or if you have a known genetic deficiency that prevents your body from breaking down chemotherapy medications safely.
This medication can interact with other prescription medicines, including certain blood thinners and antiviral treatments, which may increase your risk of severe side effects. It is also important to avoid alcohol and smoking during your treatment, as they can worsen stomach irritation and strain your liver. Always consult your doctor or pharmacist if you belong to sensitive groups, such as elderly individuals.
Uses of Doxifluridine
Medicinal Benefits
Doxifluridine is an oral anticancer medicine that is converted in the body to 5-fluorouracil, which interferes with the growth and division of cancer cells. This helps control tumour growth as part of an appropriate cancer treatment plan.
- Helps Control Cancer Growth: Interferes with DNA and RNA synthesis in rapidly dividing cancer cells, helping slow their growth.
- Supports Tumour Control: By limiting the multiplication of cancer cells, it may help control tumour growth and disease progression.
- Provides Systemic Cancer Treatment: As an oral medicine, it is absorbed into the body and can act on cancer cells beyond a single localised tumour.
- Offers Convenient Oral Administration: Being available as an oral treatment allows it to be taken without requiring an intravenous infusion for every dose.
- Supports Cancer Treatment Plans: May be used as part of an oncologist-directed treatment regimen, depending on the type and stage of cancer.
Directions for Use
- Doxifluridine can be taken with or without food.
- Follow your doctor’s instructions on the dosage and timing of this medication to ensure safe and effective use.
- Swallow Doxifluridine as a whole with a glass of water.

Drug Interactions
Inform your doctor about all medicines you are taking, as some may interact with Doxifluridine and increase the risk of side effects:
- Warfarin and Other Anticoagulants: Doxifluridine may increase the anticoagulant effect of warfarin, potentially increasing the risk of bleeding. Close monitoring of blood clotting may be required.
- Sorivudine and Related Medicines: Concomitant use with sorivudine or related compounds can cause severe toxicity because these medicines can interfere with the metabolism of fluoropyrimidines. Such combinations should be avoided.
- Other Chemotherapy Medicines: Combining Doxifluridine with other medicines that suppress the bone marrow may increase the risk of low blood cell counts and related complications. Your oncologist will determine which combinations are appropriate.

Disease/Condition Glossary
Cancer: Cancer is a genetic change in which the body's cells divide uncontrollably and spread into surrounding tissues. There are two types of cancer: benign (localized) and metastatic (spread to the whole body). Types of cancer include blood, lung, breast, etc. Cancer growth can be prevented by chemotherapy, radiation, and stem cell therapy.
FAQs
Doxifluridine is used as a prodrug in chemotherapy (adjuvant treatment of several cancers).
Doxifluridine contains doxifluridine, which is used to improve the selectivity and efficacy of cancer therapy by targeting certain abnormal markers overexpressed by cancer cells but not found in normal tissues.
While taking Doxifluridine, visit your doctor at all the appointments to ensure treatment works. Regular monitoring of blood and lipid tests and weight checks are required. An effective way of contraception should be used by both men and women while taking Doxifluridine.
Limited information is available. Discuss the risks of taking this medication with your doctor.
It is generally recommended to take Doxifluridine after your meals. This helps protect your stomach lining, reduces nausea, and assists with proper absorption of the medicine. Talk to your doctor or pharmacist if you struggle to eat before your dose.
If you experience mild diarrhoea, drink plenty of clear fluids to stay hydrated. However, if you have more than three loose stools in a single day, or if it is accompanied by fever, call your healthcare team immediately. Talk to your doctor before taking any over-the-counter anti-diarrhoea medications.
It is best to avoid alcohol during your treatment. Alcohol can irritate your stomach lining, worsen nausea, and put extra stress on your liver, which is already processing your medication. Talk to your doctor if you have concerns about avoiding alcohol.
Hair thinning or mild hair loss can occur in some people taking Doxifluridine, but it is typically less severe than with other types of intravenous chemotherapy. In most cases, hair grows back normally after the treatment is completed. Talk to your doctor if you are concerned about hair changes.
You should avoid receiving live vaccines (such as the yellow fever or oral polio vaccine) while taking this medicine, as your immune system may be lowered. Standard, non-live vaccines like the seasonal flu shot are generally safe but may be less effective. Always talk to your doctor before scheduling any vaccination.
Some patients experience a condition called hand-foot syndrome, which causes redness, tingling, swelling, or peeling on the palms of the hands and soles of the feet. Keeping your skin moisturised with a gentle cream and avoiding hot water can help. Talk to your doctor right away if you notice these skin changes.
You must avoid becoming pregnant or fathering a child while taking Doxifluridine, as it can cause serious harm to an unborn baby. Use highly reliable, non-hormonal birth control during your treatment and for a specified time afterward. Talk to your doctor for specific advice on family planning.
Regular blood tests are critical to ensure the medication is not causing silent damage to your liver, kidneys, or bone marrow. These tests check your blood cell counts to make sure your immune system remains strong enough to continue treatment safely. Talk to your doctor to understand your testing schedule.
