WHAT ZARZIO® IS USED FOR
Your doctor has prescribed Zarzio® because:
- You are receiving chemotherapy for cancer.
Some chemotherapy will reduce the number of neutrophils (white blood cells) in your body. Although Zarzio® is not a treatment for cancer, it does help the body to make new neutrophils and this will reduce the 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.
- You are receiving a bone marrow or stem cell transplant
Blood cells are produced in the bone marrow and arise from special 'parent cells', called stem cells. Some chemotherapy has toxic effects on bone marrow, so your doctor may choose to collect stem cells from your bone marrow or blood, or from a donor's bone marrow or blood, before you receive your chemotherapy. These collected stem cells are then stored and may be given back to you later, to replace those lost during chemotherapy. This procedure is called a bone marrow or stem cell transplant.
There are normally only a small number of stem cells in your blood; Zarzio® is typically used to increase this number before stem cell collection. You may also receive Zarzio® after a bone marrow or stem cell transplant, to help speed up your recovery.
- You are donating stem cells for another person
If you are aged between 16 and 60 years and have volunteered to donate your stem cells for another person, Zarzio® may be used to increase the number of stem cells in your blood before they are collected. Your stem cells can then be given to a patient after he/she has received their chemotherapy.
- You are suffering from severe chronic neutropenia
Severe chronic neutropenia is a disease in which the body does not make enough neutrophils, increasing your risk of fever and/or infection. Zarzio® helps the body to make and maintain the right number of infection-fighting neutrophils, decreasing the risk of infection and the need for antibiotics and/or hospital stays.
- You are receiving medicines for HIV infection
Some medicines used to treat HIV (Human Immunodeficiency Virus) infection, or its complications, can reduce the number of infection-fighting neutrophils in your blood. Your doctor may prescribe Zarzio® if the number of neutrophils falls too low.
By boosting your neutrophil count, Zarzio® will improve your body's ability to fight infection and may increase your chance of receiving the full dose of some of your HIV medicines. Zarzio® is not a treatment for HIV infection.
How it works
Zarzio® is also known as Filgrastim (rbe), and is a copy of a substance normally present in your body called Granulocyte Colony Stimulating Factor or G-CSF. Through the use of gene technology, Zarzio® 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 infection. 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.
Your doctor may have prescribed it for another reason.
This medicine is available only with a doctor's prescription.
BEFORE YOU START TO USE ZARZIO®
When you must not take it
Do not take this medicine if you have an allergy to:
- Filgrastim, the active ingredient, or to any of the other ingredient(s) listed at the end of this leaflet under Product Description
- any other similar medicines or products that are produced by DNA technology using the bacteria E.Coli.
Some of the 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
- rash, itching or hives on the skin
Do not use Zarzio® at the same time as your chemotherapy or radiotherapy.
Do not use Zarzio® in the 24 hours before or the 24 hours after you receive your chemotherapy, radiotherapy, bone marrow transplant or stem cell transplant.
This is because these types of treatments may stop Zarzio® from increasing the number of infection-fighting neutrophils.
Do not take this medicine after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering.
If it has expired or is damaged, return it to your pharmacist for disposal.
Do not use Zarzio® if it has been left out of the refrigerator for more than 72 hours.
If you are not sure whether you should start taking this medicine, talk to your doctor.
Before you start to take it
Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes.
Tell your doctor if you are pregnant or intend to become pregnant or are breastfeeding.
Tell your doctor if you have or have had any of the following:
- have a medical condition affecting the bone marrow or blood
- have a family history of genetic disorder
- suffer from sickle cell disease
- have problems with your kidneys, liver, heart or other organs
- have had previous treatment for cancer
- have any infections, cancers or tumours.
If you have not told your doctor about any of these things, tell him/her before you use Zarzio®. Your doctor will decide whether it is safe for you to use Zarzio®.
There is a limited experience with the use of Zarzio® in children.
Your doctor will discuss the risks and benefits of using this medicine in children.
Taking other medicines
Tell your doctor or pharmacist if you are taking any other medicines, including any that you get without a prescription from your pharmacy, supermarket or health food shop.
HOW TO USE ZARZIO®
Follow all directions given to you by your doctor, nurse or pharmacist carefully.
They may differ from the information contained in this leaflet.
If you do not understand the instructions, ask your doctor or pharmacist for help.
Zarzio® is given by injection, usually into the tissue just below the skin. This is called a subcutaneous injection and it is a simple procedure.
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 Zarzio® injection at home.
Zarzio® is sometimes given by injection into a vein. This is called intravenous injection and is generally given by a doctor or a nurse.
How much to inject
Your doctor will tell, you the strength of Zarzio® you need and how much you require. How much you need will depend on the reason for your treatment, your body weight and the number of neutrophils in your blood.
For Zarzio® to work properly, you have to use exactly as your doctor has instructed.
Where to inject
The best injection sites are:
- your abdomen, except for the area around the navel (belly button) or
- the front side of your thighs.
The sites are shown in the pictures below
Change the injection site each time you inject to avoid soreness at any one site.
When to inject
For best results, you should inject Zarzio® at about the same time each day. Your doctor will tell you when to begin your treatment and when to stop it.
How long to use it
Patients receiving chemotherapy or who have received a bone marrow or a stem cell transplant
are only required to use Zarzio® for short periods of time until the number of infection-fighting neutrophils are restored (usually 1 to 3 weeks).
Stem cell donors should receive Zarzio® treatment for 4 to 5 days.
Patients with severe chronic neutropenia are required to use Zarzio® regularly and for a long period of time, to keep the number of infection-fighting neutrophils at a normal level.
Patients with HIV infection need to use Zarzio® daily until their neutrophils numbers are normal. Usually, the dose is then reduced to three injections per week to maintain the neutrophil numbers. Your doctor will tell you how many injections you need each week and on which days they should be given.
Things to do before you inject
Make sure you have all materials you need for your injection:
- a new Zarzio® syringe
- an alcohol swab
- a puncture-resistant sharps container.
Follow these instructions exactly to help avoid contamination and possible infection.
If you are unsure, check with your doctor, nurse or pharmacist.
- Find a clean, flat working surface, such as a table, where you can inject undisturbed.
- Remove the syringe from the refrigerator. For a more comfortable injection, leave at room temperature for approximately 30 minutes. Do not warm Zarzio® in any other way (e.g. do not warm in a microwave or hot water).
- Check that the syringe has not been used before.
- Do not shake the syringe. If the Zarzio® solution appears frothy or bubbly, allow the syringe to sit undisturbed for a few minutes to reduce the froth or bubbles before measuring your dose.
- Do not remove the needle cover until you are ready to inject.
- Check the expiry date on the label. Do not use if the date has passed the last day of the month shown.
- Check the appearance of the solution. The solution should be clear and colourless or slightly yellow in colour. If it is cloudy, coloured or there are clumps or flakes, you must not use it.
- Wash and dry your hands thoroughly.
How to prepare for your injection
- Hold the syringe vertically with the needle pointing up, this helps reduce the amount of medicine that may leak out of the needle. Carefully remove the needle cover, taking care not to touch the exposed needle.
- Check the dose (in mL) that your doctor has prescribed and locate the correct volume mark on the syringe barrel. Carefully push the plunger until the grey upper edge of the plunger reaches the correct volume mark. This will push the air and any excess liquid out of the syringe.
- Double-check that you have the correct dose.
How to inject
- Clean the site where the injection is to be made with an alcohol swab, moving the alcohol swab in an expanding circle and allow the site to dry.
- Pinch a large area of skin between your thumb and forefinger, to create a firm injection site.
- Pick up the syringe and hold it as you would a pencil.
- Insert the needle directly into the skin (at an angle between 45° and 90° or as advised by your doctor, nurse or pharmacist).
- After the needle is in, pull back the plunger very slightly. If blood comes into the syringe, the needle has entered the blood vessel. Remove the needle. Select another site, clean the new site with an alcohol swab and reinsert the needle. Again, pull back the plunger very slightly to check for blood. If blood does not appear in the syringe, inject the Zarzio® by gently pushing the plunger all the way in.
- Withdraw the needle and using the alcohol swab apply pressure for several minutes to the injection site.
- Do not put the needle cover back on the used syringe. You cannot reuse the syringe.
Discard the used syringe into an approved, puncture-resistant sharps container.
Do not change the dose or the way you inject Zarzio® without consulting your doctor. Always follow your doctor's instructions.
If you forget your injection
If you miss your scheduled dose, inject it as soon as you can, provided it is still on the same day.
If you miss a whole day before you remember to inject yourself, do not take a 'catch-up' dose or increase your next dose.
Advise your doctor, nurse or pharmacist as soon as possible about the missed dose.
If you have trouble remembering to inject your dose, ask your pharmacist for some hints.
If you inject too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone Australia 13 11 26 or New Zealand 0800 POISON or 0800 764766) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much Zarzio®. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
Symptoms of an overdose may lead to neutrophil levels that are too high. Research has shown that doses almost 15 times greater than the most common dose do not immediately result in any harmful effects.
WHILE YOU ARE TAKING ZARZIO®
Things you must do
Be alert for any signs or symptoms of infection.
There are many ways an infection can show itself.
You should watch for:
- fever (a temperature of 38.2°C or greater, or as your doctor suggests)

Tell any other doctors who treat you that you are taking this medicine.
If you become pregnant during treatment with Zarzio®, tell your doctor immediately.
Keep all your doctor's appointments so that your health can be monitored.
Treatment with Zarzio® leads to changes in the number of certain blood cells. Your doctor may order blood tests to check the levels of infection-fighting neutrophils and blood cells.
Blood tests may also be undertaken after you have completed your Zarzio® treatment until your blood cells have returned to normal levels.
Things you must not do
Do not use Zarzio® to treat any other complaints unless your doctor tells you to.
Do not give Zarzio® to anyone else, even if they have the same condition as you.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are using Zarzio®.
All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical attention if you get some of the side effects.
Do not be alarmed by the following lists of side effects. You may not experience any of them.
