WARNING

Carmustine, also known as BCNU, is a chemotherapy drug used primarily to treat certain types of brain tumors, lymphoma, and other cancers. While it can be effective in treating these conditions, there are several risks and potential side effects associated with its use:

• Bone Marrow Suppression: Carmustine can reduce the production of blood cells in the bone marrow, leading to anemia, increased susceptibility to infections (due to low white blood cell count), and bleeding tendencies (due to low platelet count).
• Pulmonary Toxicity: There is a risk of lung damage associated with Carmustine, which can lead to breathing difficulties, cough, and potentially severe lung inflammation or fibrosis.
• Delayed Toxicities: Some side effects, such as delayed onset of lung fibrosis or bone marrow suppression, may not appear until weeks or months after treatment.
• Gastrointestinal Effects: Nausea, vomiting, diarrhea, and loss of appetite are common gastrointestinal side effects.
• Liver Toxicity: Carmustine can affect liver function, leading to elevated liver enzymes and potentially liver damage.
• Allergic Reactions: Some individuals may experience allergic reactions, which can range from mild rashes to severe anaphylactic reactions.
• Secondary Malignancies: There is a small risk of developing secondary cancers (such as leukemia) years after treatment with Carmustine.
• Reproductive Risks: Carmustine can cause infertility or harm to unborn babies if used during pregnancy.
• Neurological Effects: Carmustine can sometimes cause neurological side effects such as seizures, confusion, or vision changes.
• Local Tissue Damage: If Carmustine leaks out of the vein during injection, it can cause severe tissue damage.

These risks highlight the importance of careful monitoring and management by healthcare professionals when using Carmustine, as well as discussing potential benefits and risks with patients before initiating treatment.

Why is this medication prescribed?

Carmustine, also known as BCNU (Bis-chloroethyl nitrosourea), is prescribed primarily for the treatment of certain types of cancers, particularly:

• Brain Tumors: Carmustine is commonly used in the treatment of brain tumors, including glioblastoma multiforme and other types of gliomas.
• Lymphomas: It may also be used in the treatment of Hodgkin’s lymphoma and non-Hodgkin’s lymphoma.
• Multiple Myeloma: Carmustine can be part of treatment regimens for multiple myeloma, a cancer of plasma cells.

Carmustine belongs to the class of chemotherapy drugs known as nitrosoureas. It works by interfering with the DNA within cancer cells, ultimately inhibiting their growth and replication.
