Carmustine can cause a severe decrease in the number of blood cells in your bone marrow. This increases the risk that you will develop a serious infection or bleeding. If you experience any of the following symptoms, call your doctor immediately: fever, sore throat, chills, or other signs of infection; unusual bleeding or bruising; black and tarry stools; red blood in stools; bloody vomit; vomited material that looks like coffee grounds.

Carmustine also can cause lung damage, even years after treatment. The lung damage can cause death, especially in patients treated with carmustine as children. Tell your doctor if you have or have ever had lung disease.

Keep all appointments with your doctor and the laboratory. Your doctor will order certain tests to check your body’s response to carmustine.

Carmustine injection is used to treat certain types of brain tumors. Carmustine injection is also used along with prednisone to treat multiple myeloma (a type of cancer of the bone marrow). It is also used with other medications to treat Hodgkin’s lymphoma (Hodgkin’s disease) and non-Hodgkin’s lymphoma (cancer that begins in the cells of the immune system) that has not improved or that has worsened after treatment with other medications. Carmustine is in a class of medications called alkylating agents. It works by slowing or stopping the growth of cancer cells in your body.

Carmustine injection comes as a powder to be added to fluid and injected over at least 2 hours intravenously (into a vein) by a doctor or nurse in a medical office or hospital outpatient clinic. It is usually injected once every 6 weeks. It may also be injected in smaller doses once a day for 2 days in a row every 6 weeks.

Your doctor may need to delay your treatment or adjust your dose if you experience certain side effects. It is important for you to tell your doctor how you are feeling during your treatment with carmustine.
