A neutropenic fever is a temperature over 100.4°F (38°C) in a person with neutropenia. Neutropenia is when you have a low number of neutrophils in the blood. This is a type of white blood cell that helps the body fight infections.
The fever is caused by an infection.
Too few neutrophils can have a number of causes. They range from viral infections to certain medicines. It is common in people who are being treated for cancer.
Having neutropenia raises the chance of infection.
It is more common in older adults.
Other things that may raise your risk are:
- Uncontrolled cancer
- Chronic obstructive pulmonary disease (COPD)
- Liver or kidney problems
The main sign is a fever over 100.4°F (38°C). In some cases, it may be the only sign.
You may also have chills and sweating.
The infection may cause other problems. A urinary tract infection or lung infection will have their own signs.
You will be asked about your symptoms and health history. A physical exam will be done.
Your blood may be tested.
You may have more tests to find the cause of your infection.
You will be treated right away. If not, your life may be at risk.
You will be given antibiotics. Other medicines may be given to treat the type of infection you have.
Tests to find the cause of your infection can take a few days. Your medicine may be changed based on the results.
