Chemotherapy for Myelofibrosis

Chemotherapy is a type of cancer treatment that uses drugs to kill fast-growing cells, including cancer cells. In the case of myelofibrosis, chemotherapy may be used to help control symptoms, reduce spleen size, or slow the progression of the disease. It may also be used before a stem cell transplant or when other treatments are not effective.

These are the chemotherapy drugs that are used most often to treat myelofibrosis. New treatments become available all the time, so this may not be a complete list.

Please note: The side effects listed here do not represent a comprehensive list. Each chemotherapy drug has its own set of side effects and ways of working. It's important to discuss all potential side effects of a drug with your healthcare team. Be sure to tell your healthcare team about any side effects you do have.
