Patient Education

Alemtuzumab Injection (Chronic Lymphocytic Leukemia)


Alemtuzumab injection is used to treat B-cell chronic lymphocytic leukemia (B-CLL; a slowly developing cancer in which too many of a certain type of white blood cell accumulate in the body). Alemtuzumab is in a class of medications called monoclonal antibodies. It works by activating the immune system to destroy cancer cells. Alemtuzumab is also available as an injection (Lemtrada) that is used to treat multiple sclerosis (a disease in which the nerves do not function properly; you may experience weakness, numbness, loss of muscle coordination and problems with vision, speech, and bladder control). This monograph only gives information about alemtuzumab injection (Campath) for B-CLL. If you are receiving alemtuzumab for multiple sclerosis, read the monograph entitled Alemtuzumab Injection (Multiple Sclerosis).
