Busulfan Injection

Busulfan injection can cause a severe decrease in the number of blood cells in your bone marrow. Tell your doctor and pharmacist about all the medications you are taking. If you receive busulfan with other medications that may cause a low blood count, the side effects of the medications may be more severe. If you experience any of the following symptoms, call your doctor immediately: fever, sore throat, ongoing cough and congestion, or other signs of infection; unusual bleeding or bruising.

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.

Busulfan may increase the risk that you will develop other cancers. Talk to your doctor about the risks of receiving busulfan.

🔔 Why is this medication prescribed?

Busulfan injection is used to treat a certain type of chronic myelogenous leukemia (CML; a type of cancer of the white blood cells) in combination with other medications to destroy bone marrow and cancer cells in preparation for a bone marrow transplant. Busulfan is in a class of medications called alkylating agents. It works by slowing or stopping the growth of cancer cells in your body.

🔔 How should this medicine be used?

Busulfan comes as a solution (liquid) to be given intravenously (into a vein) over 2 hours by a doctor or nurse in a medical facility. It is usually given every 6 hours for 4 days (for a total of 16 doses) before bone marrow transplant.

Busulfan injection may cause seizures during therapy with the medication. Your doctor will give you another medication to help prevent seizures before and during therapy with busulfan injection.

Major health insurance companies have faced legal trouble over their claim denial practices. In February 2018, the insurance commissioner of California announced plans to investigate Aetna’s coverage denial practices after a former medical director of the insurance company admitted that he never once looked at a patient’s medical records when deciding whether to deny claims over the three years he worked in the position, according to CNN.

🔔 Other uses for this medicine

Busulfan injection is also used in combination with other drugs to destroy the bone marrow and cancer cells in preparation for a bone marrow transplant in people with other types of cancer.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
