WARNING

Busulfex (busulfan) injection is a chemotherapy medication primarily used to treat certain types of leukemia. Like many chemotherapy drugs, Busulfex carries several risks and potential side effects, including:

• Bone Marrow Suppression: Busulfex can suppress bone marrow function, leading to decreased production of blood cells (red blood cells, white blood cells, and platelets). This may result in anemia, increased susceptibility to infections, and bleeding tendencies.
• Secondary Cancers: Long-term use of Busulfex may increase the risk of developing secondary cancers, such as leukemia or solid tumors.
• Infertility: Busulfex may cause infertility in both men and women due to its effects on the reproductive system.
• Gastrointestinal Issues: Common side effects of Busulfex include nausea, vomiting, diarrhea, and loss of appetite.
• Liver Toxicity: Busulfex can cause liver toxicity, leading to elevated liver enzymes and, in rare cases, liver failure.
• Pulmonary Toxicity: There have been reports of pulmonary toxicity, including pulmonary fibrosis, associated with Busulfex use.
• Hypersensitivity Reactions: Some individuals may experience allergic reactions to Busulfex, which can range from mild skin reactions to severe anaphylaxis.
• Neurological Effects: Busulfex can cause neurological side effects such as seizures, confusion, and peripheral neuropathy.
• Skin Reactions: Skin rash, itching, and other dermatological reactions are possible with Busulfex use.

It’s important for patients receiving Busulfex to be closely monitored by healthcare professionals for any signs of toxicity or adverse reactions. Additionally, patients should discuss the risks and benefits of Busulfex treatment with their healthcare provider before starting therapy.

Why is this medication prescribed?

Busulfex (busulfan) injection is prescribed for the treatment of certain types of leukemia, particularly chronic myeloid leukemia (CML) and certain types of acute myeloid leukemia (AML). It is often used as part of a conditioning regimen before a hematopoietic stem cell transplant (HSCT) to help destroy cancer cells and suppress the immune system to prevent rejection of the transplanted cells.

How should this medicine be used?

Busulfex is administered intravenously (into a vein) by a healthcare professional in a hospital or clinic setting. The dosage and frequency of administration will vary depending on factors such as the patient’s age, weight, overall health, and the type and stage of leukemia being treated.

Before each dose of Busulfex, patients may receive medications to prevent nausea and vomiting. The injection is typically given slowly over a period of 2 to 3 hours to reduce the risk of certain side effects.

It’s important for patients to follow their healthcare provider’s instructions carefully when receiving Busulfex treatment. They should not change the dosage or frequency of administration without consulting their doctor. Additionally, patients should report any side effects or concerns to their healthcare provider promptly.

Other uses for this medicine

While Busulfex (busulfan) injection is primarily used for the treatment of certain types of leukemia, it may also be used off-label for other conditions, such as:

• Multiple Myeloma: Busulfex may be used in combination with other medications for the treatment of multiple myeloma, a type of cancer that affects plasma cells in the bone marrow.
• Thalassemia: Busulfex may be used as part of a conditioning regimen before a hematopoietic stem cell transplant (HSCT) in patients with thalassemia, a genetic blood disorder.
• Myelodysplastic Syndrome (MDS): Busulfex may be used in the treatment of myelodysplastic syndrome, a group of disorders characterized by abnormal blood cell production in the bone marrow.

What special precautions should I follow?

As for special precautions for Busulfex injection, patients and healthcare providers should consider the following:

• Monitoring: Patients receiving Busulfex should be closely monitored by healthcare professionals for signs of bone marrow suppression, liver toxicity, pulmonary toxicity, and other adverse reactions.
