Ifosfamide may cause serious (even fatal) side effects (including urinary problems such as hemorrhagic cystitis, mental/mood changes, blood/bone marrow disorders), which may require your treatment with this medication to be stopped. Tell your doctor right away if you develop symptoms such as pink/bloody urine, frequent/painful urination, severe drowsiness, confusion, unusual changes in behavior, or hallucinations. Blood/bone marrow disorders can affect your body's ability to stop bleeding, or fight infection. Tell your doctor right away if you develop easy bruising/bleeding or signs of infection (such as sore throat that doesn't go away, fever, chills).

Ifosfamide is used to treat various cancers. It works by slowing or stopping the growth of cancer cells.
