Ifosfamide is used with other medicines to treat testicular cancer in men.

Ifosfamide is usually given after other treatments have failed.

Ifosfamide may also be used for purposes not listed in this medication guide.

You should not be treated with ifosfamide if you are allergic to it, or if you have a medical condition that causes urination problems (such as an enlarged prostate).

Tell your doctor if you have ever had:

• kidney disease;
• heart disease;
• a bladder infection;
• treatment with busulfan; or
• radiation treatment of your bladder.

Using ifosfamide may increase your risk of developing other cancers, such as leukemia. Ask your doctor about this risk.

Ifosfamide can cause birth defects if a woman is exposed to it during pregnancy.

Use effective birth control to prevent pregnancy, whether you are a man or a woman. Ifosfamide use by either parent may cause birth defects. Keep using birth control for at least 6 months after treatment.

This medication may affect fertility (your ability to have children), whether you are a man or a woman. Some women using ifosfamide have stopped having periods, or started having symptoms of early menopause.

A woman receiving ifosfamide should not breast-feed.
