Neutropenic fever is a fever while a patient is neutropenic. A fever in a neutropenic patient is a temperature of 100.4°F or 38.0°C or greater. An infection can have few signs in a neutropenic patient because they do not have the white blood cells to start an inflammatory response. Many times, a fever is the only sign of an infection.
A neutropenic fever is an emergency in a cancer patient. Patients with neutropenia are unable to fight infection. This is due to a low number of neutrophils. An infection can quickly turn into sepsis and become life-threatening. Along with the fever, the patient may have chills and rigors (shaking).
If you have a fever of or greater than 100.4°F or 38.0°C, you need to call your provider right away. Intravenous (IV) antibiotics should be given very quickly with a neutropenic fever to prevent sepsis. Broad-spectrum antibiotics are used because they treat many types of infections.
A full infection work-up will be done if you have a neutropenic fever. This involves: a chest x-ray, blood cultures, urine studies, checking the central line, checking the skin and, if you have any specific infectious symptoms, those will also be tested. For example, if you have a fever, stomach pain and loose stools, an abdominal (belly) CT scan may be ordered and stool (bowel movement) studies taken.
If a reason for the fever is found, more specific antibiotics will be given. A medication such as acetaminophen will be given to “break” the fever. When a fever “breaks” or resolves, you may sweat heavily.
If you have a fever for more than 24 hours, the infection work-up may be repeated. It may be done every 24 hours until you no longer have a fever. A source of infection is often not found in neutropenic patients. It is important to continue to treat with antibiotics until you are no longer having fevers and are not neutropenic. Once you are no longer neutropenic, antibiotics may be stopped and, if you do not have a fever for 24 hours, you may be able to go home. If a source of infection is found, you will finish the course of antibiotic treatment.
While neutropenic, there are steps you can take to help prevent a neutropenic fever:
A neutropenic fever is an emergency! If you develop any signs or symptoms of infection, you should call your provider right away.
Signs and symptoms of infection to look for:
Fever or infection in a neutropenic patient is an emergency. Make sure that you have a phone number for use during office hours and an emergency phone number for your provider’s office during non-business hours. They should be kept near a home phone or can be programmed into a cellular phone. Do not wait to call your provider and follow the instructions given to you as to how to proceed.
