Warnings
Black Box Warnings
The drug should be administered under the supervision of an experienced cancer chemotherapy physician because of the possibility of severe toxic reactions
Patient should be hospitalized for initiation of the therapy because of the risk for severe toxic reactions
Contraindications
None
Cautions
Discontinue in case of stomatitis, esophagopharyngitis, leukopenia, thrombocytopenia, intractable vomiting, GI bleeding, hemorrhage
Severe diarrhea may occur; withhold fluorouracil for Grade 3 or 4 diarrhea until resolved or decreased in intensity to Grade 1, then resume fluorouracil at a reduced dose; administer fluids, electrolyte replacement, or antidiarrheal treatments as necessary
Therapy can cause neurologic toxicity, including acute cerebellar syndrome and other neurologic events, based on postmarketing reports; neurologic symptoms included confusion, disorientation, ataxia, or visual disturbances; withhold fluorouracil for neurologic toxicity; there are insufficient data on risks of resumption of fluorouracil in patients with neurologic toxicity that has resolved
Treatment can cause cardiotoxicity, including angina, myocardial infarction/ischemia, arrhythmia, and heart failure; reported risk factors for cardiotoxicity are administration by continuous infusion rather than intravenous bolus and presence of coronary artery disease; withhold fluorouracil for cardiotoxicity; risks of resumption of fluorouracil in patients with cardiotoxicity that has resolved not established
Mucositis, stomatitis or esophagopharyngitis, which may lead to mucosal sloughing or ulceration, can occur with fluorouracil; the incidence is reported to be higher with administration by intravenous bolus compared with administration by continuous infusion; withhold administration for Grade 3 or 4 mucositis; resume fluorouracil at a reduced dose once mucositis has resolved or decreased in severity to Grade 1
Clinically significant elevations in coagulation parameters have been reported during concomitant use of warfarin and fluorouracil; closely monitor patients receiving concomitant coumarin-derivative anticoagulants such as warfarin for INR or prothrombin time in order to adjust anticoagulant dose accordingly
Myelosuppression
- Treatment can cause severe and fatal myelosuppression which may include neutropenia, thrombocytopenia, and anemia
- The nadir in neutrophil counts commonly occurs between 9 and 14 days after drug administration; obtain complete blood counts prior to each treatment cycle, weekly if administered on a weekly or similar schedule, and as needed
- Withhold fluorouracil until Grade 4 myelosuppression resolves; resume fluorouracil at a reduced dose when myelosuppression has resolved or improved to Grade 1 in severity
Palmar-plantar erythrodysesthesia
- Therapy can cause palmar-plantar erythrodysesthesia, also known as hand-foot syndrome (HFS)
- Symptoms of HFS include a tingling sensation, pain, swelling, and erythema with tenderness, and desquamation; HFS occurs more commonly when fluorouracil is administered as a continuous infusion than when administered as a bolus injection, and has been reported to occur more frequently in patients with previous exposure to chemotherapy
- HFS is generally observed after 8 to 9 weeks of drug administration but may occur earlier; institute supportive measures for symptomatic relief of HFS; withhold administration for Grade 2 or 3 HFS; resume fluorouracil at a reduced dose when HFS is completely resolved or decreased in severity to Grade 1
Patients with low or absent dipyrimidine dehydrogenase activity
- Based on postmarketing reports, patients with certain homozygous or certain compound heterozygous mutations in the DPD gene that result in complete or near complete absence of DPD activity are at increased risk for acute early-onset of toxicity and severe, life-threatening, or fatal adverse reactions caused by fluorouracil (e.g., mucositis, diarrhea, neutropenia, and neurotoxicity)
- Patients with partial DPD activity may also have increased risk of severe, life-threatening, or fatal adverse reactions caused by fluorouracil
- Withhold or permanently discontinue fluorouracil based on clinical assessment of the onset, duration and severity of the observed toxicities in patients with evidence of acute early-onset or unusually severe toxicity, which may indicate near complete or total absence of DPD activity
- No fluorouracil dose has been proven safe for patients with complete absence of DPD activity; there is insufficient data to recommend a specific dose in patients with partial DPD activity as measured by any specific test
Hyperammonemic encephalopathy
- Drug can cause hyperammonemic encephalopathy in absence of liver disease or other identifiable cause, based on postmarketing reports
- Signs or symptoms of hyperammonemic encephalopathy reported to start within 72 hours after initiation of fluorouracil infusion; these included altered mental status, confusion, disorientation, coma, or ataxia, in the presence of concomitant elevated serum ammonia level
- Withhold fluorouracil for hyperammonemic encephalopathy and initiate ammonia-lowering therapy; the risks of resumption of fluorouracil in patients with hyperammonemic encephalopathy that has resolved have not been established
Pregnancy & Lactation
Pregnancy
There are no adequate and well-controlled studies with fluorouracil in pregnant women; based on its mechanism of action, the drug can cause fetal harm when administered to a pregnant woman
If this drug is used during pregnancy, or patient becomes pregnant while taking this drug, apprise the patient of the potential hazard to a fetus
Contraception
- Females: Based on mechanism of action, drug can cause fetal harm when administered to a pregnant woman; advise females of reproductive potential to use effective contraception during treatment with fluorouracil and for up to 3 months following cessation of therapy
- Males: Fluorouracil may damage spermatozoa; advise males with female partners of reproductive potential to use effective contraception during and for 3 months following cessation of therapy
Infertility
- Females: Advise females of reproductive potential that, based on animal data, fertility may be impaired while receiving fluorouracil
- Males: Advise males of reproductive potential that, based on animal data, fertility may be impaired while receiving fluorouracil
Animal data
- Administration to rats and mice during selected periods of organogenesis, at doses lower than a human dose of 12 mg/kg, caused embryolethality and teratogenicity; malformations included cleft palate and skeletal defects
- In monkeys, maternal doses of fluorouracil higher than an approximate human dose of 12 mg/kg resulted in abortion
Lactation
Not known whether fluorouracil or its metabolites are present in human milk; because many drugs are present in human milk and because of potential for serious adverse reactions in nursing infants from fluorouracil, a decision should be made whether to discontinue nursing or to discontinue drug, taking into account importance of drug to the mother
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Inhibits DNA synthesis during S phase by inhibition of thymidylate synthetase
Pharmacokinetics
Half-Life: 16 min
Onset: 2-7 d, but may take up to 12 wk
Duration: 24 hr
Metabolism: liver
Metabolites: urea, fluorouracil, dihydrofluorouracil, expired CO2 metabolite
Excretion: urine
Pharmacogenomics
Dihydropyrimidine dehydrogenase (DPD), an enzyme encoded by the DPYD gene, is the rate-limiting step in pyrimidine catabolism and deactivates >80% of 5FU standard doses and the 5FU prodrug capecitabine
Contraindicated in patients with DPD deficiency; causes severe toxicity with conventional doses (ie, grade III/IV toxicity and potentially fatal neutropenia, mucositis, and diarrhea)
Because true DPD deficiency is rare and because the clinical implications of partial deficiency are still unclear, screening for mutations prior to initiating therapy is not warranted

FLUOROURACIL - INJECTION
(flewr-oh-YOUR-uh-sill)
COMMON BRAND NAME(S): Adrucil
USES: Fluorouracil is used to treat various types of cancer. It is a chemotherapy drug that is used to slow or stop cancer cell growth.
HOW TO USE: This medication is usually given by injection into a vein by a health care professional. It may also be given by other methods of injection depending upon your medical condition. The dosage is based on your medical condition, body size, and response to therapy.
SIDE EFFECTS: Nausea, vomiting, loss of appetite, dry/itchy skin, or skin darkening may occur. Nausea and vomiting can be severe. In some cases, drug therapy may be necessary to prevent or relieve nausea and vomiting. Not eating before your treatment may help relieve vomiting. Changes in diet such as eating several small meals or limiting activity may help lessen some of these effects. If any of these effects last or get worse, tell your doctor or pharmacist promptly.Mild diarrhea is also a common side effect. However, diarrhea can rarely become severe, causing very serious problems due to dehydration. Tell your doctor right away if you develop: diarrhea that is severe or doesn't stop, abdominal or stomach pain/cramping, or blood/mucus in your stool.Temporary hair loss may occur. Normal hair growth should return after treatment has ended.Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.Hand and foot problems sometimes occur with fluorouracil use. You can prevent or reduce these problems by protecting your hands and feet from a great deal of heat or pressure. For example, avoid taking hot baths/showers, handwashing dishes with hot water, taking long walks, and rubbing your hands/feet. Tell your doctor right away if you develop the following symptoms on your hands/feet: redness, peeling skin, blisters, pain, numbness, tingling, or swelling. If you develop these symptoms, consult your doctor for treatment options (such as reducing your dose or stopping fluorouracil therapy, applying ice packs to the hands/feet).Tell your doctor right away if you have any serious side effects, including: headache, mental/mood changes (such as confusion), vision changes, unusual eye movements, loss of coordination, unusual tiredness.Get medical help right away if you have any very serious side effects, including: easy bruising/bleeding, blood in the urine, black/bloody stools, vomit that looks like coffee grounds, stomach/abdominal pain, chest pain, jaw/left arm pain, fast/slow/irregular heartbeat, mouth sores, sore throat, painful swallowing, heartburn, pain/redness/swelling of the arms/legs.This medication can lower the body's ability to fight an infection. Tell your doctor promptly if you develop any signs of an infection such as sore throat that doesn't go away, fever, or chills.A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.Fluorouracil can commonly cause a rash that is usually not serious. However, you may not be able to tell it apart from a rare rash that could be a sign of a severe reaction. Get medical help right away if you develop a rash.This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.In the US -Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch.In Canada - Call your doctor for medical advice about side effects. You may report side effects to Health Canada at 1-866-234-2345.
PRECAUTIONS: Before using fluorouracil, tell your doctor or pharmacist if you are allergic to it; or to flucytosine; or to capecitabine; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.Before using this medication, tell your doctor or pharmacist your medical history, especially of: poor nutrition, decreased bone marrow function/blood cell disorders (such as anemia, leukopenia, thrombocytopenia), a certain enzyme deficiency (dihydropyrimidine dehydrogenase - DPD), a serious infection, liver problems, kidney problems.Tell your health care professional that you are using fluorouracil before having any immunizations/vaccinations. Avoid contact with people who have recently received live vaccines (such as flu vaccine inhaled through the nose).To lower the chance of getting cut, bruised, or injured, use caution with sharp objects like razors and nail cutters, and avoid activities such as contact sports.This medication may make you more sensitive to the sun. Limit your time in the sun. Avoid tanning booths and sunlamps. Use sunscreen and wear protective clothing when outdoors. Tell your doctor right away if you get sunburned or have skin blisters/redness.Tell your doctor if you are pregnant or plan to become pregnant.
