Carmustine for injection should be administered under the supervision of a qualified physician experienced in the use of cancer chemotherapeutic agents. Bone marrow suppression, notably thrombocytopenia and leukopenia, which may contribute to bleeding and overwhelming infections in an already compromised patient, is the most common and severe of the toxic effects of carmustine. Blood counts should be monitored weekly for at least 6 weeks after a dose. At the recommended dosage, courses of carmustine should not be given more frequently than every 6 weeks. Pulmonary toxicity from carmustine appears to be dose related, as patients receiving greater than 1400 mg/m(2) cumulative dose are at significantly higher risk than those receiving less. Delayed pulmonary toxicity can occur years after treatment, and can result in death, particularly in patients treated in childhood .
Carmustine injection is used alone or together with other medicines to treat certain type of brain tumors (e.g., glioblastoma, brainstem glioma, medulloblastoma, astrocytoma, ependymoma, and metastatic brain tumors), cancer of the lymph system (e.g., Hodgkin's disease, non-Hodgkin's lymphoma), and a certain type of cancer in the bone marrow (e.g., multiple myeloma). It may also be used to treat other kinds of cancer, as determined by your doctor.
Carmustine belongs to the group of alkylating agents. It interferes with the growth of cancer cells, which are eventually destroyed. Since the growth of normal body cells may also be affected by carmustine, other effects may occur. Some of these may be serious and must be reported to your doctor. Other effects (e.g., hair loss), may not be serious but may cause concern. Some effects may not occur for months or years after the medicine is used.
Before you begin treatment with carmustine, you and your doctor should talk about the benefits this medicine will do as well as the risks.

While you are being treated with carmustine injection, and after you stop treatment with it, do not have any immunizations (vaccines) without your doctor's approval. Carmustine may lower your body's resistance and the vaccine may not work as well for you or you might get the infection the vaccine is meant to prevent. In addition, you should not be around other persons living in your household who receive live vaccines because there is a chance they could pass the virus on to you. Some examples of live vaccines include measles, mumps, influenza (nasal flu vaccine), poliovirus (oral form), rotavirus, and rubella. Do not get close to them and do not stay in the same room with them for very long. If you have questions about this, talk to your doctor.
Carmustine can temporarily lower the number of white blood cells in your blood, increasing the chance of getting an infection. It can also lower the number of platelets, which are necessary for proper blood clotting.

If carmustine accidentally seeps out of the vein into which it is injected, it may damage some tissues and cause scarring. Tell the doctor or nurse right away if you notice redness, pain, or swelling at the injection site.
This medicine may increase risk of lung problems while smoking.
