Granulocyte colony stimulating factor, also called G-CSF, Filgrastim or Neupogen®, is a man-made form of a natural human hormone. It is a colorless liquid that is either injected under the skin or given into a vein. G-CSF helps the body make infection-fighting white blood cells, called neutrophils. Some St. Jude patients need this medicine to help build up neutrophils that have been destroyed by chemotherapy.
How to give G-CSF
Inject just below the skin
- If your G-CSF is injected under the skin (subcutaneous injection), a nurse will teach you how to give the injection (refer to “Do you know… How to give subcutaneous injections” or “Do you know… Subcutaneous tissue infusion set”).
- Your subcutaneous injection dose is __________ micrograms.
- For each dose, draw __________ ml into the syringe. After you give the shot, discard the rest of the medicine in the vial. Do not use the same vial of G-CSF more than one (1) time. Refer to “Do you know… Withdrawing medicine from a vial.”
Note: For patients receiving G-CSF doses less than 200 micrograms, the pharmacy will draw up individual doses into syringes.
By IV (into a vein)
If your G-CSF is given into a vein, a nurse will give the G-CSF dose.
Possible side effects
- Mild bone pain
- Pain/bruising at the injection site
These are the most common side effects, but there may be others. Please report all side effects to the doctor or nurse.
In case of a severe side effect or reaction, call the doctor, nurse, or pharmacist at 901-595-3300. If you are outside the Memphis area, dial toll-free 1-866-2STJUDE (1-866-278-5833), and press 0 once the call is connected.
- Until you are ready to use it, keep the G-CSF refrigerated but not frozen. G-CSF may be kept at room temperature for up to 24 hours if needed.
- Before giving a dose of G-CSF, take it out of the refrigerator about an hour before and let it warm to room temperature.
- G-CSF should always be a clear, colorless liquid. Do not use G-CSF if the liquid looks cloudy, changes color, or has flakes or specks in it.
- Do not use G-CSF if the date on the vial has expired. If you receive G-CSF in syringes from the pharmacy, do not use them after the expiration date listed on the syringe. For safety, throw away the unused syringes in a patient sharps container.
- Do not shake the vial of G-CSF. Bubbles make it hard to withdraw the correct dose.
