Ifosfamide, sold under the brand name Ifex among others, is a chemotherapy medication used to treat a number of types of cancer. This includes testicular cancer, soft tissue sarcoma, osteosarcoma, bladder cancer, small cell lung cancer, cervical cancer, and ovarian cancer. It is administered by injection into a vein.

Common side effects include hair loss, vomiting, blood in the urine, infections, and kidney problems. Other severe side effects include bone marrow suppression and decreased level of consciousness. Use during pregnancy will likely result in harm to the baby. Ifosfamide is in the alkylating agent and nitrogen mustard family of medications. It works by disrupting the duplication of DNA and the creation of RNA.

Ifosfamide was approved for medical use in the United States in 1987. It is on the World Health Organization's List of Essential Medicines.
