CSFs are supportive medications that can help prevent hospitalization from infection after some types of cancer treatment. These medications are not necessary for everyone undergoing cancer treatment, just those patients who are at a higher risk of developing febrile neutropenia. Most chemotherapy schedules are not associated with a high risk of developing febrile neutropenia. Your doctor can help you understand CSF treatment and how to manage the accompanying side effects.
