What is in this leaflet

This leaflet answers some common questions about Ziextenzo.

It does not contain all the available information.

It does not take the place of talking to your doctor, nurse or pharmacist.

All medicines have risks and benefits. Your doctor has prescribed Ziextenzo after considering its likely benefit to you, as well as the potential risks.

Keep this leaflet with your medicine. You may need to read this information again.

What Ziextenzo is used for

Ziextenzo is used following chemotherapy to help fight infection.

Some chemotherapy will reduce the number of neutrophils in your body. Although Ziextenzo is not a treatment for cancer, it does help the body to make new neutrophils. This will reduce your chance of developing infections that might require antibiotics and/or hospital stays. It may even increase your chance of receiving your chemotherapy on time and at the right dose.

How it works

Ziextenzo is a long acting form of Recombinant Human Granulocyte Colony Stimulating Factor or G-CSF. Using gene technology, Ziextenzo is produced in a specific type of bacteria, called E. coli.

G-CSF is produced in the bone marrow and assists in the production of neutrophils, which are a type of white blood cell. Neutrophils help the body fight infections by surrounding and destroying the bacteria that cause the infections.

G-CSF also helps neutrophils to do this work better.

Ask your doctor if you have any questions about why this medicine has been prescribed for you.

This medicine is available only with a doctor’s prescription.

Before you use it

When you must not use it

Do not have Ziextenzo if you have an allergy to:

  • any medicine containing pegfilgrastim or Filgrastim
  • any of the ingredients listed at the end of this leaflet
  • any medicines or products that are produced using the bacteria E. coli.

Symptoms of an allergic reaction may include:

  • shortness of breath, wheezing or difficulty breathing
  • swelling of the face, lips, tongue or other parts of the body
  • skin rash, itching or hives.

Do not use Ziextenzo at the same time as your chemotherapy or radiotherapy.

Do not use Ziextenzo within 24 hours after you receive chemotherapy. This is because the chemotherapy medicine may stop Ziextenzo from increasing the number of infection – fighting neutrophils.

Do not use Ziextenzo after the expiry date (EXP) printed on the pack

Do not use Ziextenzo if the packaging is torn or shows signs of tampering.

Do not use Ziextenzo if it has been left out of the refrigerator for more than three days.

How to use it

Ziextenzo is given by injection, into the tissues just below the skin. This is called a subcutaneous injection.

Your doctor, nurse or pharmacist may suggest that you or your carer be taught how to give a subcutaneous injection. This will allow you to have your Ziextenzo injection at home.

Carefully follow all directions given to you by your doctor, pharmacist or nurse. They may differ from the information in this leaflet.

If you do not understand the instructions, ask your doctor, pharmacist or nurse for help.

How to inject Ziextenzo using a pre-filled syringe with an automatic needle guard

To help avoid possible infections and to ensure that you use the medicine correctly, it is important that you follow these instructions.

Read ALL the way through these instructions before injecting. It is important not to try to inject yourself until you have been trained by your doctor, nurse or pharmacist. The carton contains ZIEXTENZO® pre-filled syringe individually sealed in a plastic blister.

Your ZIEXTENZO® pre-filled syringe with needle guard

After the medicine has been injected, the needle guard will be activated to cover the needle. The needle guard is intended to protect healthcare professionals, caregivers and patients from accidental needle sticks after the injection.

What you additionally need for your injection:

  • Alcohol swab.
  • Cotton ball or gauze.
  • Sharps disposal container.

Important safety information

Caution: Keep the pre-filled syringe out of the sight and reach of children.

  1. Do not open the carton until you are ready to use the pre-filled syringe.
  2. Do not use the pre-filled syringe if the seal of the blister is broken, as it may not be safe for you to use.
  3. Never leave the pre-filled syringe unattended where others might tamper with it.
  4. Do not shake the pre-filled syringe.
  5. Be careful not to touch the needle guard wings before use. By touching them, the needle guard may be activated too early.
  6. Do not remove the needle cap until just before you give the injection.
  7. The pre-filled syringe cannot be re-used. Dispose of the used pre-filled syringe immediately after use in a sharps container.

Storage of the ZIEXTENZO® pre-filled syringe

  1. Store the blistered pre-filled syringe in its carton to protect it from light.
  2. Store in the refrigerator between 2 °C and 8 °C. Do not freeze.
  3. Prior to use‚ remove the pre-filled syringe from the refrigerator and allow ZIEXTENZO® to reach room temperature (up to a maximum of 25 °C) for approximately 15-30 minutes.
  4. Do not use the pre-filled syringe after the expiry date which is stated on the carton or syringe label. If it has expired, return the entire pack to the pharmacy.

The injection site

The injection site is the place on the body where you are going to use the pre-filled syringe.

  • The recommended site is the front of your thighs. You may also use the lower abdomen, but not the area 5 centimetres around the navel (belly button).
  • Choose a different site each time you give yourself an injection.
  • Do not inject into areas where the skin is tender, bruised, red, scaly or hard. Avoid areas with scars or stretch marks.

If a caregiver is giving you the injection, the outer upper arms may also be used.

Preparing the ZIEXTENZO® pre-filled syringe ready for use

  1. Take the carton containing the blistered pre-filled syringe out of the refrigerator and leave it unopened for approximately 15-30 minutes so that it reaches room temperature.
  2. When you are ready to use the pre-filled syringe, open the blister and wash your hands thoroughly with soap and water.
  3. Clean the injection site with an alcohol swab.
  4. Remove the pre-filled syringe from the blister. Check to ensure the plastic transparent needle guard is situated over the barrel of the glass syringe. If the transparent needle guard is covering the needle cap (as shown below) the syringe has been activated, DO NOT use this syringe and take a new syringe. The figure below shows a ready to use syringe.
  5. Inspect the pre-filled syringe. The liquid should be clear. Its colour may vary from colourless to slightly yellowish. You may see a small air bubble in the liquid. This is normal. Do not use the pre-filled syringe if any other particulates and/or discolouration are observed.
  6. Do not use if the syringe is broken or activated. Return the ZIEXTENZO® pre-filled syringe and the package to your pharmacy.



How to use the ZIEXTENZO® pre-filled syringe

Carefully pull the needle cap straight off. You may see a drop of liquid at the end of the needle. This is normal.

Gently pinch the skin at the injection site and insert the needle as shown. Push the needle all the way in to ensure that the medication can be fully administered.

Holding the pre-filled syringe as shown, slowly depress the plunger as far as it will go so that the plunger head is completely between the needle guard wings.

Keep the plunger pressed fully down while you hold the syringe in place for 5 seconds.

Keep the plunger fully depressed while you carefully pull the needle straight out from the injection site and let it go off your skin.

Slowly release the plunger and allow the syringe needle guard to automatically cover the exposed needle.

There may be a small amount of blood at the injection site. You can press a cotton ball or gauze onto the injection site and hold it for 10 seconds. Do not rub the injection site. You may cover the injection site with a small adhesive bandage, if needed.

Disposal instructions

Dispose of the used syringe in a sharps container (closable, puncture resistant container).

Do not throw away any medicines via wastewater or household waste. Ask your doctor or pharmacist how to throw away medicines you no longer use. These measures will help protect the environment. Any unused product or waste material should be disposed of in accordance with local requirements.
