Febrile neutropenia is a medical condition characterized by a fever and low levels of neutrophils in the blood, which are a type of white blood cell that fights bacterial infections. There are several synonyms for febrile neutropenia, including neutropenic sepsis, neutropenic fever, and chemotherapy-induced neutropenia. These terms indicate the underlying causes of the condition, such as sepsis or the side effects of chemotherapy. Other related terms in this context include bone marrow suppression, immunosuppression, and myelosuppression. Effective treatment for febrile neutropenia typically involves antibiotics and close monitoring to prevent further complications and ensure a successful recovery.
