What is neutropenia?

Neutropenia (say "noo-truh-PEE-nee-uh") means that your blood has too few white blood cells called neutrophils. White blood cells are an important part of your body's immune system. Neutrophils help protect your body from infection by killing bacteria.

Fever is a common sign of infection. So if you have neutropenia, your doctor may ask you to check your temperature every day and keep a written record of your readings.

Common signs of infection include:

• Fever of 100.4 °F (38 °C) or higher. (This may be the only symptom.)
• Chills or sweating.
• Cough or shortness of breath.
• Nausea or vomiting.
• Redness, pain, swelling, or warmth around a sore or I.V. site.

Other possible signs include a sore throat or mouth sores, vaginal drainage or itching, diarrhea, pain when you urinate, and a need to urinate often.

Neutropenia is sometimes found during a routine blood test. Your doctor will ask about your past health and any symptoms you have. You may have a physical exam. You may also have tests to check the level of white blood cells and other blood cells. Other tests may be done to find the cause.

If your white blood cell count is very low, your doctor may give you medicine to help protect you, such as:

• Antibiotics to help prevent infection.
• Medicine to help your body make white blood cells.

If you get an infection or a fever, you may need to be treated in the hospital. To fight the infection, your doctor may give you antibiotics through a vein (intravenous, or I.V.). This gets the medicine into your bloodstream quickly. Some people may be allowed to take antibiotics by mouth.

• Take your medicines exactly as prescribed. Call your doctor if you have any problems with your medicine.
• Eat a healthy, balanced diet. Eat foods with a lot of fiber. This helps to prevent constipation.

Prevent infections

• Take your temperature several times a day, as your doctor suggests. Keep a written record of your temperature readings. Fever is a common symptom of infection. And it may be the only symptom.
• Use a soft toothbrush. Do not floss your teeth. Talk with your doctor about other steps to prevent infections in your mouth.
• Wash your hands often with soap and water, especially before you eat and after you use the bathroom.
• If you are a woman, use sanitary napkins (pads) instead of tampons. Do not douche.
• Do not use rectal thermometers or suppositories.
• Avoid tasks that might expose you to germs, such as disposing of pet feces or urine.
• Avoid crowds of people and anyone who might have an infection or an illness such as a cold or the flu. You may need to avoid people who have recently had certain kinds of vaccinations.
• Even small injuries can get infected. Take steps to prevent cuts, burns, and sunburns.
• If you have severe neutropenia, your doctor may advise you to avoid fresh fruits, vegetables, and flowers.
