Busulfex (Busulfan) belongs to the group of cancer-fighting medications called antineoplastics, and specifically to the group of antineoplastics called alkylating agents. It is used to treat Leukemia (cancer of white blood cells). Busulfex (Busulfan) prevents the growth of cancer cells by interfering with the genetic material DNA, which is necessary for the reproduction of cells.

It can also be used in combination with other chemotherapy regimens prior to stem cell transplants for certain leukemias, lymphomas (cancer of the lymph cells), Multiple Myeloma (cancer of the plasma cells), and other genetic conditions that have not responded to other therapies or are very aggressive.

Busulfex (Busulfan) may be available under multiple brand names and/or in several different forms. Any specific brand name of Busulfex (Busulfan) may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of Busulfex (Busulfan) may not be used for all of the conditions discussed here.

Your doctor may have suggested Busulfex (Busulfan) for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking Busulfex (Busulfan), speak to your doctor. Do not stop taking Busulfex (Busulfan) without consulting your doctor.

Do not give Busulfex (Busulfan) to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take Busulfex (Busulfan) if their doctor has not prescribed it.



The recommended dose and dosing schedule of Busulfex (Busulfan) varies according to the specific type of cancer being treated, the response to therapy, other medications or treatments being used, and is also based on body size. Busulfex (Busulfan) is either taken as oral tablet(s) daily or injected into a vein through a site on the skin that has been specially prepared for this purpose.

The dose should be taken at the same time each day to have the best effect. Your doctor may want you to drink extra fluids while taking Busulfex (Busulfan) to prevent kidney problems.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

It is important to use Busulfex (Busulfan) exactly as prescribed by your doctor.

Busulfex (Busulfan) may cause nausea, vomiting, and loss of appetite, but it is important that you continue to use the medication. Do not stop taking it without talking with your doctor. If you vomit shortly after taking a dose of Busulfex (Busulfan), call your doctor for instructions on whether to skip that dose or to take another dose.

If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

As well as interfering with the genetic material DNA of cancer cells, Busulfex (Busulfan) can interfere with some of your normal cells. This can cause a number of side effects such as hair loss and mouth sores. Keep track of any side effects and report them to your doctor at your next appointment. 

Store Busulfex (Busulfan) at room temperature, protect it from light and moisture, and keep it out of the reach of children.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.
