1. What Cardioxane is and what it is used for

Cardioxane contains a substance called dexrazoxane. This substance belongs to a group of medicines which protect the heart (cardioprotective medicines).

Cardioxane is used to prevent heart damage when medicines called anthracyclines (such as doxorubicin or epirubicin) are used during breast cancer treatment in adults.

2. What you need to know before you are given Cardioxane

You must not be given Cardioxane

  • If you are under 18 years old and your planned dose of anthracycline is considered low – talk to your doctor about this.
  • If you are allergic (hypersensitive) to dexrazoxane.
  • If you are breast-feeding (see also “Pregnancy and breast-feeding”).
  • If you are given yellow-fever vaccine.

If any of the above apply, you must not be given this medicine.

Warnings and precautions

Talk to your doctor, pharmacist or nurse before you are given Cardioxane:

  • If you have or have had liver or kidney problems.
  • If you have or have had a heart attack, heart failure, uncontrolled chest pain and heart valve problems.
  • If you are pregnant or plan to become pregnant (see also “Pregnancy and breast-feeding”).
  • If you are allergic to dexrazoxane.

You should also be aware that:

  • Your doctor may carry out tests before and during the treatment with Cardioxane to see how well the treatment is working and to check the function of some of your organs, such as your heart, kidneys or liver.
  • Your doctor may carry out blood tests during the treatment with Cardioxane to monitor your bone marrow function. If you are receiving high-dose cancer treatment (e.g. chemotherapy or radiation) and are also being treated with high doses of Cardioxane, your bone marrow function may be reduced. This may affect the production of red blood cells, white blood cells, and platelets.
  • Cardioxane may increase the risk of developing leukaemia (cancer of the blood).
  • During treatment with Cardioxane, women of childbearing potential and men should use effective contraception. Women and men should continue using contraception for at least six months after Cardioxane treatment has been stopped (see also “Pregnancy and breast-feeding”).
  • The combination of Cardioxane with your cancer treatment may increase the risk of blood clots.
  • If Cardioxane powder or solution gets on your skin, tell your doctor straight away. You or your doctor should immediately rinse the affected area thoroughly with water.

Children and adolescents

The long-term benefits and risks of this medicine in children and adolescents are not yet clear. Your doctor will advise on benefits and risks of this medicine.

Older people (over 65 years old)

The doctor may adjust your treatment with Cardioxane according to your health condition (in case of heart, liver or kidney problems).

Other medicines and Cardioxane

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

It is not advisable to take other medicines without telling your doctor as there may be interactions between Cardioxane and other medicines:

  • Vaccines: you must not use Cardioxane if you will receive yellow fever vaccine and it is not recommended that you use Cardioxane if you will receive a vaccine containing live virus particles.
  • Phenytoin, a treatment against seizures.
  • Cyclosporin or tacrolimus (both treatments lower the body's immune system and are used to prevent organ rejection after an organ transplant).
  • Myelosuppressive medicines (decrease production of red, white, or coagulating blood cells).

Pregnancy and breast-feeding

  • You will not be given Cardioxane if you are pregnant or had planned to become pregnant, unless your doctor decides it is necessary.
  • Women of childbearing potential and men should use effective contraception during treatment with Cardioxane and for at least six months after Cardioxane treatment has been stopped.
