WARNING

Busulfan is a chemotherapy medication used primarily to treat certain types of cancers, such as chronic myelogenous leukemia (CML) and certain types of bone marrow disorders. While it can be effective in treating these conditions, there are several risks associated with taking Busulfan:

• Bone Marrow Suppression: Busulfan can suppress the bone marrow’s ability to produce blood cells, leading to conditions like anemia, leukopenia (low white blood cell count), and thrombocytopenia (low platelet count). This can increase the risk of infections, bleeding, and fatigue.
• Increased Risk of Secondary Cancers: Long-term use of Busulfan has been associated with an increased risk of developing secondary cancers, such as acute myeloid leukemia (AML).
• Gastrointestinal Effects: Busulfan can cause nausea, vomiting, diarrhea, and other gastrointestinal disturbances. These side effects can affect a person’s quality of life and may require supportive care.
• Liver Toxicity: Busulfan can cause liver damage, leading to elevated liver enzymes, hepatitis, and liver failure in severe cases. Regular monitoring of liver function is essential during Busulfan therapy.
• Pulmonary Toxicity: Rarely, Busulfan can cause lung problems, such as pulmonary fibrosis or interstitial lung disease, which can result in difficulty breathing and decreased lung function.
• Reproductive Risks: Busulfan can cause infertility or reduced fertility in both men and women. It may also increase the risk of birth defects if taken during pregnancy.
• Skin Reactions: Some individuals may experience skin reactions, such as rash, itching, or skin discoloration, while taking Busulfan.

It’s essential for patients taking Busulfan to be closely monitored by their healthcare providers for these potential risks and side effects. Additionally, patients should discuss the risks and benefits of Busulfan therapy with their healthcare team before starting treatment.

Why is this medication prescribed?

Busulfan, when prescribed as a tablet, is typically used in the treatment of certain types of cancers and bone marrow disorders, including:

• Chronic Myelogenous Leukemia (CML): Busulfan may be prescribed as part of the treatment regimen for CML, particularly in patients who cannot tolerate or have failed other therapies.
• Preparative Regimen for Stem Cell Transplantation: Busulfan is often used as part of the conditioning regimen before hematopoietic stem cell transplantation (HSCT) to suppress the recipient’s immune system and make room for the transplanted stem cells.
• Bone Marrow Disorders: Busulfan may be used in the treatment of other bone marrow disorders, such as myelodysplastic syndromes (MDS) or aplastic anemia.

How should this medicine be used?

The dosage and duration of Busulfan treatment vary depending on the specific condition being treated, the patient’s overall health, and other factors. Busulfan tablets are usually taken orally, with or without food, as directed by a healthcare provider.

Here are some general guidelines for using Busulfan tablets:

• Follow Prescribed Dosage: Take Busulfan exactly as prescribed by your doctor. Do not alter the dosage or stop taking the medication without consulting your healthcare provider.
• Regular Monitoring: Your doctor will monitor your blood cell counts and liver function regularly during Busulfan treatment to ensure the medication is working effectively and to detect any potential side effects.
• Timing of Administration: Take Busulfan tablets at the same time(s) each day to maintain a consistent level of the medication in your bloodstream.
• Swallow Whole: Swallow the tablets whole with a full glass of water. Do not crush, chew, or break the tablets unless instructed otherwise by your doctor.

Other uses for this medicine

Busulfan, in addition to its primary use in treating certain cancers and bone marrow disorders, may also have other off-label uses. Some of these off-label uses include conditioning therapy before stem cell transplantation and treatment of certain autoimmune diseases. However, these uses should only be pursued under the guidance and supervision of a qualified healthcare professional.

What special precautions should I follow?

When taking Busulfan, there are several special precautions to keep in mind to ensure safe and effective treatment:

• Medical Monitoring: Regular medical monitoring is crucial during Busulfan treatment. Your doctor will monitor your blood cell counts, liver function, and overall health to assess how your body is responding to the medication and to detect any potential side effects or complications.
