Warnings and cautions

Talk to your doctor or nurse before using Fluorouracil Teva.

Take special care with Fluorouracil Teva:

  • if you have too low several white blood cells and platelets (you will have to take blood samples to check this).
  • if you have a sore mouth, fever, or any bleeding or if you are weakened (these symptoms may be due to your blood containing a very low number of blood cells ).
  • if you have kidney problems.
  • if you have liver problems.
  • if you have heart problems. Tell your doctor if you feel chest pain during treatment.
  • if you know that the enzyme dihydropyrimide dehydrogenase (DPD) is partially inactive in you. 
  • if the enzyme a dihydropyrimide dehydrogenase (DPD) is partially or completely inactive in someone in your family
  • if you have received high doses of radiation in the pelvic area.
  • if you have gastrointestinal side effects (diarrhea, gastrointestinal bleeding), inflammation of the oral mucosa, or bleeding elsewhere.
  • if you experience nerve damage such as lack of coordination of muscle movements or tremors.
  • if you are of childbearing age. Women and men of childbearing potential must use effective contraception during treatment and 6 months afterward. See also section “Pregnancy, breast-feeding and fertility”.

DPD Deficiency: DPD deficiency is a congenital condition that is not usually associated with health problems unless you use certain medications. If you have DPD deficiency and are taking Fluorouracil Teva, you have an increased risk of serious side effects (listed in section 4 Possible side effects ). It is recommended that you be tested for DPD deficiency before starting treatment. If you have no enzyme activity, do not take Fluorouracil Teva. If you have reduced enzyme activity ( partial deficiency), your doctor may prescribe a lower dose. Serious and life-threatening side effects can still occur even if your test result for DPD deficiency is negative. 

Contact healthcare professionals immediately if you experience the following signs or symptoms: new onset of confusion, disorientation or otherwise altered mental status, problems with balance or coordination, visual disturbances. These can be signs of brain disease that can lead to coma and death if left untreated.

Avoid prolonged exposure to sunlight when treated with this medicine as fluorouracil may increase sensitivity to sunlight. Radiation just before or after treatment with fluorouracil can cause increased pigmentation on skin areas exposed to sunlight.

Other medicines and Fluorouracil Teva

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines. This is very important, as taking more than one medicine at the same time may intensify or weaken the effect of the medicines. Show larger

You must not take brivudine (antiviral medicine used to treat shingles or chickenpox) while you are being treated with fluorouracil (including during the rest period when you are not using fluorouracil). If you have taken brivudine, you must wait at least 4 weeks after stopping brivudine before starting fluorouracil treatment. See also section “Do not use Fluorouracil Teva”.

The effect of Fluorouracil Teva may be affected by certain medicines containing the following active substances:

  • cyclophosphamide (an anticancer medicine)
  • vincristine (a medicine used to treat cancer)
  • methotrexate, (an anticancer medicine)
  • cisplatin (an anticancer medicine)
  • doxorubicin (an anticancer medicine)
  • metronidazole (an antibiotic )
  • calcium leucovorin (also called calcium folinate – used to reduce the harmful effects of anti-cancer drugs)
  • interferon alfaallopurinol (used to treat gout )

  • cimetidine (used to treat stomach ulcers )

Fluorouracil Teva may affect the effectiveness of certain medicines containing the following active substances:

  • phenytoin (used to treat epilepsy/seizures) as combined treatment with fluorouracil may increase the levels of phenytoin in the blood.
  • warfarin (used to counteract blood clots). Combination with fluorouracil may affect the breakdown of warfarin so that the warfarin dose needs to be lowered.

Other medicines in combination with Fluorouracil Teva

  • levamisole (used to treat machine infection), in combination with Fluorouracil Teva, may cause liver damage.
  • clozapine (an antipsychotic drug) in combination with Fluorouracil Teva should be avoided due to the increased risk of the severe reduction in granulocytes, a type of white blood cell vinorelbine (a medicine used to treat cancer) in combination with Fluorouracil Teva and folic acid can cause painful damage and inflammation of the oral mucosa.
  • tamoxifen (a medicine used to treat cancer) in combination with cyclophosphamide, methotrexate, and Fluorouracil Teva may increase the risk of blood clots.
  • Thiazide diuretics (diuretics, antihypertensive drugs) in addition to a combination of cyclophosphamide, methotrexate, and Fluorouracil Teva may result in a decrease in the number of granulocytes (a type of white blood cell ).
  • Mitomycin (cytotoxic antibiotic ) in combination with Fluorouracil Teva may reduce red blood cell counts and acute renal failure.

People treated with Fluorouracil Teva are at risk of developing a weakened immune system. Vaccination with live vaccines should therefore be avoided.
