All to know



What is it and how is it used?

Fasturtec contains the active ingredient rasburicase.
Rasburicase is used to treat or prevent high blood levels of uric acid from occurring in patients with disorders of the blood cells (haematological diseases) who are about to receive or are receiving chemotherapy treatment.

When chemotherapy is given, cancer cells are destroyed, releasing large amounts of uric acid into the bloodstream.
Fasturtec works by allowing uric acid to more easily be removed from the body by the kidneys.


What do you have to consider before using it?

Do not use Fasturtec if you:

  • are allergic (hypersensitive) to rasburicase, other uricases or any of the other ingredients of Fasturtec
  • have a history of haemolytic anaemia (an illness caused by red blood cells being abnormally broken down).
Take special care with Fasturtec if you:

  • have a history of any kind of allergy.

Tell your doctor if you have ever had any allergic type reactions due to other medicines as Fasturtec can cause allergic-type reactions, including severe cases.

It is not known whether the chance of developing an allergic reaction is increased if treatment with Fasturtec is repeated.

In case of disorders of the blood in which red blood cells are abnormally broken down (haemolysis) or abnormal blood pigment levels (methaemoglobinaemia), your doctor will immediately and permanently discontinue treatment with Fasturtec.

Using other medicines

Please tell your doctor if you are taking, or have recently taken, any other medicines, including medicines obtained without a prescription.

Pregnancy and breast feeding

Tell your doctor if you are, or think you may be pregnant, or if you are breast-feeding.

Driving and using machines

No information on the ability to drive and use machines is available.

How is it used?

Fasturtec is to be given to you before or during the start of your course of chemotherapy.

Fasturtec is injected slowly into a vein, which should take about 30 minutes.

Your dose will be calculated according to your body weight.
The recommended dose is 0.20 mg per kg of body weight per day in both children and adults.

It will be given once a day, for up to 7 days.
During treatment with Fasturtec, your doctor will carry out blood tests to check the levels of uric acid and decide how long you will be treated for.
Your doctor may also test your blood to make sure that you do not develop any blood disorders.

If you use more Fasturtec than you should

If it does occur, the doctor will closely monitor the effects on your red blood cells and treat any symptoms that follow.

If you have any further questions on the use of this product, ask your doctor, nurse or hospital pharmacist.

What are possible side effects?

Like all medicines, Fasturtec can cause side effects, although not everybody gets them. Fasturtec will be administered at the same time as other medicines that may also cause side effects.

If you suddenly notice:

  • a swelling of the face, lips, tongue or other part of your body
  • a shortness of breath, wheezing or breathing problems
  • a rash, itching or hives tell your doctor, nurse or hospital pharmacist immediately as these may be signs of a serious allergic reaction (anaphylaxis). These are rare (affecting between 1 in 1,000 and 1 in 10,000 patients).

Common side effects (affecting between 1 in 10 and 1 in 100 patients):

  • high fever
  • allergic reactions, mainly rashes and urticaria.

Uncommon side effects (affecting between 1 in 100 and 1 in 1,000 patients):

  • severe allergic reaction, such as low blood pressure (hypotension) and wheezing or difficulty in breathing (bronchospasm)
  • severe diarrhoea
  • severe vomiting
  • severe nausea
  • severe headache
  • blood disorders such as a disorder of the blood in which red blood cells are abnormally broken down (haemolysis) or abnormal blood pigment levels (methaemoglobinaemia).

Rare (affecting between 1 in 1,000 and 1 in 10,000 patients):

  • runny or blocked nose, sneezing, facial pressure or pain (rhinitis).

If you notice any of these, tell your doctor, nurse or hospital pharmacist.

If any of the side effects gets serious, or if you notice any side effects not listed in this leaflet, please tell your doctor, nurse or hospital pharmacist.

The following information is intended for medical or healthcare professionals only: See section 3 ?How to use Fasturtec? and practical information on preparation and handling given below.

Fasturtec must be reconstituted with the entire volume of the supplied solvent (e.g. 1.5 mg rasburicase vial to be reconstituted with the 1 ml solvent ampoule; 7.5 mg rasburicase vial to be reconstituted with the 5 ml solvent ampoule). Reconstitution results in a solution with a concentration of 1.5 mg/ml to be further diluted with sodium chloride 9 mg/ml (0.9%).

Reconstitution of the solution:
Add the content of one ampoule of solvent to one vial containing rasburicase and mix by swirling very gently under controlled and validated aseptic conditions.
Do not shake.
Inspect visually prior to use. Only clear and colourless solutions without particles should be used. For single-use only, any unused solution should be discarded.
The solvent contains no preservative. Therefore the reconstituted solution should be diluted under controlled and validated aseptic conditions.

Dilution before infusion:
The required volume of the reconstituted solution depends on the patient's body weight. The use of several vials may be necessary to obtain the quantity of rasburicase required for one administration. The required volume of the reconstituted solution, taken from one or more vials, is to be further diluted with sodium chloride 9 mg/ml (0.9%) solution to make a total volume of 50 ml. The concentration of rasburicase in the final solution for infusion depends on the patient's body weight.

The reconstituted solution contains no preservative. Therefore the diluted solution should be infused immediately.

The final solution should be infused over 30 minutes.

Sample handling:
If it is necessary to monitor a patient?s uric acid level, a strict sample-handling procedure must be followed to minimise ex vivo degradation of the analyte. Blood must be collected into pre-chilled tubes containing heparin anticoagulant. Samples must be immersed in an ice/water bath. Plasma samples should immediately be prepared by centrifugation in a pre-cooled centrifuge (4 °C). Finally, plasma must be maintained in an ice/water bath and analysed for uric acid within 4 hours.
