Busulfan
About Busulfan
Busulfan is a specialised medicine used primarily to prepare patients for a bone marrow or stem cell transplant. It works by clearing out existing bone marrow cells to make room for healthy new donor cells. This critical preparation process is essential for treating certain serious blood and bone marrow conditions, such as leukemia.
Because this treatment is highly specialised, it is given as an injection in a hospital setting. It is not a daily at-home medicine, but rather a carefully timed series of infusions given over several consecutive days before your transplant. Your medical team will manage the schedule precisely, and maintaining this consistency is vital for the success of your transplant.
While this medicine is a crucial step in your treatment, it can cause side effects. Common issues include nausea, vomiting, mouth sores, and temporary hair loss. It can also cause more serious complications, such as liver damage, seizures, or lung problems. You must inform your healthcare team immediately if you experience any unusual symptoms during or after your treatment.
Do not receive this medicine if you have had a severe allergic reaction to it in the past. Before starting, tell your doctor if you have a history of seizures, liver disease, lung problems, or if you are pregnant or planning to become pregnant. This medicine is not suitable for pregnant women as it can harm the unborn baby.
This medication can interact with other substances, including certain anti-seizure drugs and common pain relievers like acetaminophen, which can increase the risk of liver damage. It is also important to talk to your doctor if you are breastfeeding or if you are an older adult, as special precautions may be needed.
Uses of Busulfan
Medicinal Benefits
Using Busulfan as prescribed helps prepare your body for a successful stem cell transplant. Here are the key benefits you can expect:
- Prepares the bone marrow for transplantation: Destroys diseased or abnormal bone marrow cells, creating space for healthy donor stem cells to grow.
- Helps reduce transplant rejection: Suppresses the immune system, helping your body accept the transplanted stem cells more successfully.
- Supports recovery after transplantation: Promotes successful donor stem cell engraftment, helping rebuild a healthy blood and immune system.
Directions for Use
- Follow your doctor's instructions on the dosage and timing of this medication to ensure effective use.
- The healthcare provider or nurse will administer Busulfan.
- Do not self-administer.

View AllDrug Warnings
- Take prescribed anti-seizure medicine: Ensure you take any anti-seizure medication your doctor prescribes before your infusion, as this helps prevent potential seizures.
- Monitor the injection site: Tell your nurse immediately if you feel any burning, pain, swelling, or redness where the IV is placed.
- Avoid live vaccines: Do not receive any live vaccines during your treatment or for several months afterward, as your body's immune defenses will be very low.
- Use strict birth control: Both men and women should use highly effective birth control during and for some time after treatment to prevent pregnancy, as the drug can harm a developing baby.
- Keep up with blood tests: Attend all scheduled blood tests so your medical team can closely monitor your liver function and blood cell levels.
- Watch for liver complications: Contact your medical team urgently if you develop rapid weight gain, swelling of the abdomen, pain in the upper right side of your abdomen, or yellowing of the skin or eyes, as these may be signs of sinusoidal obstruction syndrome (SOS), also called veno-occlusive disease (VOD).
- Discuss fertility preservation early: If you may wish to have children in the future, speak with your healthcare team before treatment starts about options such as sperm banking, egg freezing, or embryo freezing.
Drug Interactions
- Acetaminophen: Taking acetaminophen close to your infusion can increase the risk of liver damage.
- Anti-seizure medications: Drugs like phenytoin can speed up how your body processes Busulfan, potentially making it less effective.
- Certain antifungal medicines: Drugs like itraconazole can slow down the clearance of Busulfan, increasing the risk of severe side effects.

- Pregnancy testing is recommended for females of reproductive potential prior to initiating treatment with Busulfan.
- Busulfan should be taken under strict medical supervision. The doctor will regularly monitor your condition while taking Busulfan.
- Keep all appointments with your doctor and the laboratory. Your doctor will order laboratory tests before, during and after your treatment to check your body's response to busulfan to see if your blood cells are affected by this drug.
- Do not donate sperm during treatment with Busulfan and for three months after your last dose.
Patients Concern
Disease/Condition Glossary
Cancer: Cancer is a condition where cells in a specific body part grow and reproduce uncontrollably. The cancerous cells can invade and destroy surrounding healthy tissue, including organs. Cancer sometimes begins in one body part before spreading to other areas.
Chronic myeloid leukemia (CML) is also known as chronic myelogenous leukemia. It is a type of cancer that begins in the bone marrow's blood-forming cells.
Polycythemia vera is a form of blood cancer (pol-e-sy-THEE-me-uh VEER-uh). It causes your bone marrow to produce an abnormally large number of red blood cells. These extra cells thicken your blood, delaying its flow and even causing major complications like blood clots.
Essential thrombocythemia (ET) is a rare blood condition that causes an abnormally large amount of platelets to develop in the blood. These are blood cells that help with coagulation. Clotting is referred to as thrombosis, and blood cells are referred to as cythaemia.
Myelofibrosis (MF) is a rare type of blood cancer characterized by the formation of scar tissue, known as 'fibrosis,' in the bone marrow. As scar tissue grows, the bone marrow is unable to produce enough healthy blood cells.
FAQs
Busulfan is used to treat Cancers of the blood, such as Chronic myeloid leukaemia, Polycythaemia vera, Thrombocythemia, and Myelofibrosis.
Busulfan contains Busulfan, which works by interfering with the production of blood cell DNA. Thus, it prevents the cells from growing and maturing, which ultimately leads to the death of these cells.
Suppose you have polycythaemia vera (PV). Busulfan can control your blood count, which helps to reduce the risk of both blood clots and bleeding.
If you have essential thrombocythemia (ET), using busulfan to reduce and control platelet counts minimises the risk of blood clotting, bleeding and developing MF.
It is recommended not to be used in the population who are allergic to Busulfan or any other ingredients in this medication, is a pregnant woman, has too low blood cell counts, or suffers from severe liver or hepatic impairment.
Yes, Busulfan can cause a severe decrease in the number of blood cells in your bone marrow. Your doctor will monitor peripheral blood cell counts and adjust the dose as appropriate.
It is injected directly into a vein (intravenously) by a trained healthcare professional in a hospital or transplant clinic, usually over several hours for a few consecutive days. Talk to your doctor.
Yes, temporary hair loss is a very common side effect of this treatment. Your hair will typically begin to grow back after your transplant process and recovery are complete. Talk to your doctor.
This medication can temporarily increase your risk of experiencing a seizure. Your healthcare team will typically prescribe an anti-seizure medicine beforehand to keep you safe during your infusions. Talk to your doctor.
You should avoid receiving live vaccines during and for several months after your treatment, as your immune system will be highly weakened. Always consult your transplant specialist before getting any vaccine. Talk to your doctor.
It can cause stress or damage to your liver, including a serious condition where the small blood vessels in the liver become blocked. Your healthcare team will perform regular blood tests to monitor your liver health. Talk to your doctor.
You should avoid alcohol entirely during this treatment, as both alcohol and the medicine are processed by your liver, and combining them significantly increases your risk of liver damage. Talk to your doctor.
The medicine is processed and cleared from your bloodstream relatively quickly, usually within 24 hours after your last dose, though its effects on your bone marrow and immune system will last much longer. Talk to your doctor.
Yes. Busulfan can reduce fertility in both men and women and may sometimes cause permanent infertility. If future pregnancy is important to you, discuss fertility-preservation options with your healthcare team before starting treatment.
