Uses For filgrastim-aafi

Filgrastim-aafi injection is used to treat neutropenia (low white blood cells) that is caused by cancer medicines. It is a synthetic (man-made) form of a substance that is naturally produced in your body called a colony stimulating factor. Filgrastim-aafi helps the bone marrow to make new white blood cells.

When certain cancer medicines are used to fight cancer cells, they also affect the white blood cells that fight infections. Filgrastim-aafi is used to prevent or reduce the risk of infections while you are being treated with cancer medicines. Filgrastim-aafi is also used to help the bone marrow recover after a bone marrow transplantation, for a process called peripheral blood progenitor cell collection in cancer patients.

Filgrastim-aafi is available only with your doctor's prescription.

For non-prescription products, read the label or package ingredients carefully.

Proper Use of filgrastim-aafi

A nurse or other trained health professional may give you filgrastim-aafi. It is given as a shot under your skin or into a vein.

You may be taught how to give filgrastim-aafi at home. Make sure you understand all of the instructions before giving yourself an injection. Use filgrastim-aafi only as directed by your doctor. Do not use more of it, do not use it more often, and do not use it for a longer time than your doctor ordered. You will also be shown the body areas where this shot can be given. Use a different body area each time you give yourself a shot. Keep track of where you give each shot to make sure you rotate body areas. This will help prevent skin problems from the injections. Do not inject into skin areas that are tender, red, bruised, hard, or has scars or stretch marks.

Filgrastim-aafi comes with patient instructions. Read and follow these instructions carefully. Ask your doctor if you have any questions about:

  • How to prepare the injection.
  • The proper use of disposable syringes.
  • How to give the injection.
  • How long the injection can be stored at home.

Start using the medicine 24 hours or more after you finish your chemotherapy. However, do not use it within 24 hours before you begin another chemotherapy.

Allow the medicine to warm to room temperature before you inject it. If the liquid in the prefilled syringe or vial has changed color, looks cloudy, or if you see particles in it, do not use it.

Do not shake the prefilled syringe. Use the syringe or vial only once. Do not save leftover medicine.

If you use the prefilled syringe, make sure you know how to use the needle guard. After giving an injection, slide the needle guard forward over the needle until you hear a "click." The needle guard will safely cover the used needle.

Each syringe or vial of medicine is good for only one dose. Throw the syringe or vial away after your dose. Do not save unused medicine from an opened vial or syringe. Do not shake the medicine.

Dosing

The dose of filgrastim-aafi will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of filgrastim-aafi. If your dose is different, do not change it unless your doctor tells you to do so.

The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

Call your doctor right away if you have swelling or puffiness and are urinating less often, trouble breathing, feeling of fullness, dizziness, or feeling faint.

Check with your doctor right away if you or your child has black or tarry stools, bleeding gums, blood in the urine or stools, pinpoint red spots on the skin, or unusual bleeding or bruising after receiving filgrastim-aafi.
