Simply Put, What is Busulfan?
Busulfan is a very strong chemotherapy medicine. Its main job is to destroy diseased cells in your body.
Before you get a stem cell transplant, doctors need to clear out your sick bone marrow. Busulfan cleans out the unhealthy cells and makes space for new, healthy stem cells to grow.
You cannot take this medicine at home as a pill. It is given through a vein as an infusion, much like an intravenous drip.
Medical professionals give this treatment only in a hospital or specialized clinic. You are in safe hands with a trained team watching over you.
Things to Tell Your Doctor Before Treatment Starts

Things to Watch Out For During Treatment
Your body may react in new ways while you take this medicine. Knowing what to watch for helps you stay safe.
Watch Closely for Infections
Busulfan can lower the number of white blood cells that fight germs in your body. This means you have a much higher chance of catching infections.
- Stay far away from anyone who has a fever, cold, body aches, or a sore throat.
- If you develop a fever, chills, a cough, or a sore throat, do not take medicine on your own. Call your doctor or treatment hospital right away.
Watch for Bleeding and Bruising
This medicine can lower your platelets, which are the blood cells that help stop bleeding. Because of this,
- Check to see if you bruise much easier than normal.
- Watch for bleeding gums, frequent nosebleeds, blood in your urine, or black stools.
- Tell your doctor right away if you notice any of these bleeding signs.
