side effects of certain chemotherapy agents. It is referred to as a chemoprotectant,
antineoplastic adjunct, or cardioprotective agent. (For more detail, see "How this
drug works" section below).
What Dexrazoxane Is Used For:
- Dexrazoxane is used to reduce the incidence and severity of heart problems associated
with the chemotherapy agent doxorubicin in women being treated for metastatic breast
- It is only used for women who have received a high cumulative dose of doxorubicin
and who would benefit from continued therapy.
- It is not recommended for women who are just starting doxorubicin. (There is some
evidence that the addition of dexrazoxane when just starting doxorubicin may interfere
with the antitumor effects of doxorubicin).
Note: If a drug has been approved for one used, physicians
may elect to use this same drug for other problems if they believe it may be helpful.
How Dexrazoxane Is Given:
- This medication is given through a vein (intravenously, IV)

- The amount of dexrazoxane that you will receive depends on many factors, including
your height and weight, your general health or other health problems, and the type
of cancer or condition being treated. Your doctor will determine your dose
- The side effects seen with treatment of dexrazoxane are likely attributable to the
other chemotherapy medications being given in combination with dexrazoxane.

Monitoring and Testing:
A baseline heart evaluation is recommended before starting treatment, and a heart
function test will be done as your doctor prescribes. You will be checked
regularly by your health care professional while you are taking dexrazoxone, to
monitor side effects and check your response to therapy. Periodic blood work
to monitor your complete blood count (CBC) as well as the function of other organs
(such as your kidneys and liver) will also be ordered by your doctor.
How Dexrazoxane Works:
Chemoprotective agents are drugs that are used with certain types of chemotherapy
to protect the body from or minimize the side effects of the chemotherapy.
These medications do not eliminate side effects in general. Rather, they protect
the body from some of the potentially serious side effects. These drugs also
have side effects of their own so they are used only with specific types of chemotherapy
or when the benefit clearly is greater than the risk.
How dexrazoxane works is not fully understood. It is thought that by being
broken down within the cells into other chemicals, these chemicals interfere with
harmful elements known as free radicals. These free radicals are thought to
be responsible, in part, for heart problems caused by certain types of chemotherapy
