What is mechlorethamine?
Mechlorethamine is a cancer (antineoplastic) medication. Mechlorethamine interferes with the growth of cancer cells and slows their growth and spread in the body.
Mechlorethamine is used to treat several types of cancer, such as Hodgkin's Disease, lymphosarcoma, chronic myelocytic or chronic lymphocytic leukemia, lung cancer and mycosis fungoides. Mechlorethamine is also used to treat certain other blood disorders (polycythemia vera) and is sometimes injected into body spaces, such as the chest, abdomen or the sack containing the heart, to stop the accumulation of fluids caused by cancer.
Mechlorethamine may also be used for purposes other than those listed in this medication guide.
