Before you receive fluorouracil, tell your doctor if you have cancer that has spread to your bone marrow, liver or kidney disease, if you have ever had radiation treatment of your pelvic area, or if you have ever received other cancer medications in the past.
Do not receive fluorouracil without telling your doctor if you are pregnant. It could harm the unborn baby. Use effective birth control, and tell your doctor if you become pregnant during treatment.
You should not breast-feed a baby while being treated with fluorouracil.
Fluorouracil can lower blood cells that help your body fight infections. Avoid being near people who have colds, the flu, or other contagious illnesses. Do not receive a live vaccine during your fluorouracil treatment. Contact your doctor at once if you develop signs of infection such as fever, chills, sore throat, flu symptoms, easy bruising or bleeding, mouth sores, or unusual weakness.
Fluorouracil is a cancer medication. Fluorouracil interferes with the growth of cancer cells and slows their growth and spread in the body.
Fluorouracil is used to treat cancer of the colon, rectum, breast, stomach, or pancreas.
Fluorouracil treats only the symptoms of cancer but does not treat the cancer itself.
Fluorouracil may also be used for purposes other than those listed in this medication guide.
You should not receive this medication if you are allergic to fluorouracil, or if you have:
If you have any of these other conditions, you may need a dose adjustment or special tests to safely receive this medication:

It is not known whether fluorouracil passes into breast milk. However, you should not breast-feed a baby while being treated with fluorouracil.
Fluorouracil is given as an injection through a needle placed into a vein. You will receive this injection in a clinic or hospital setting.
Your first dose of fluorouracil will be given in a hospital setting where you can be closely watched in case the medication causes serious side effects.
Fluorouracil injections are usually given daily for 3 or 4 days in a row, and then every other day for another 3 or 4 days. This treatment cycle may be repeated once a month. You may also receive a weekly dose. Follow your doctor's instructions.
How often you need fluorouracil injections will depend on many factors, including side effects and how your body responds to the medication. Try not to miss any appointments for your fluorouracil injections.
Your white blood cell (WBC) counts may need to be checked with a blood test before you receive each fluorouracil dose. This will help your doctor determine whether you can safely receive the injection.
Tell your caregivers if you feel any burning, pain, or swelling around the IV needle when the medicine is injected.
Fluorouracil can lower blood cells that help your body fight infections. This can make it easier for you to bleed from an injury or get sick from being around others who are ill. Contact your doctor at once if you develop signs of infection such as fever, chills, sore throat, flu symptoms, easy bruising or bleeding (nosebleeds, bleeding gums), mouth sores, or unusual weakness.
Contact your doctor if you miss an appointment for your fluorouracil injection.
Since fluorouracil is given by a healthcare professional, an overdose is not likely to occur.
Overdose symptoms may include more severe forms of the side effects that fluorouracil can cause, such as nausea, vomiting, diarrhea, bloody or tarry stools, coughing up blood, or any signs of infection (such as fever, chills, sore throat, and mouth sores).
Avoid being near people who have colds, the flu, or other contagious illnesses. Contact your doctor at once if you develop signs of infection.
Do not receive a "live" vaccine while you are being treated with fluorouracil, and avoid coming into contact with anyone who has recently received a live vaccine. There is a chance that the virus could be passed on to you. Live vaccines include measles, mumps, rubella (MMR), oral polio, chickenpox (varicella), BCG (Bacillus Calmette and Guérin), and nasal flu vaccine.
