How It Works

Cyclophosphamide is an alkylating agent and is related to mustard gas. It causes cell death by interfering with the way genetic material (DNA) in the cell multiplies.

Cyclophosphamide is available as an intravenous (IV) medicine and as tablets for oral use in 25 mg and 50 mg. The type and extent of a disease and your body size determine the exact dose and schedule of administering this medicine.

Why It Is Used

Cyclophosphamide is used to treat many forms of cancer, including:

Breast cancer.
Leukemia.
Lung cancer.
Multiple myeloma.

Non-Hodgkin's lymphoma.
Ovarian cancer.
Sarcoma.

Cyclophosphamide is also used to treat other diseases, such as:

Arthritis.
Lupus.
Myasthenia gravis.
Nephrotic syndrome.
Wegener's granulomatosis.

Cyclophosphamide is often used before a bone marrow transplant or after another type of transplant, such as a kidney or liver transplant.
