Instructions for injecting Neupogen



Neupogen contains sorbitol
This medicine contains 50 mg sorbitol in each ml.
Sorbitol is a source of fructose. If you (or your child) have hereditary fructose intolerance
(HFI), a rare genetic disorder, you (or your child) must not receive this medicine. Patients with
HFI cannot break down fructose, which may cause serious side effects.
You must tell your doctor before receiving this medicine if you (or your child) have HFI or
if your child can no longer take sweet foods or drinks because they feel sick, vomit or get
unpleasant effects such as bloating, stomach cramps or diarrhoea.

3. How to use Neupogen
Always use this medicine exactly as your doctor has told you. Check with your doctor, nurse
or pharmacist if you are not sure.
How is Neupogen given and how much should I take?
Neupogen is usually given as a daily injection into the tissue just under the skin (known as a
subcutaneous injection). It can also be given as a daily slow injection into the vein (known as
an intravenous infusion). The usual dose varies depending on your illness and weight. Your
doctor will tell you how much Neupogen you should take.

1. What Neupogen is and what it is used for

Patients having a bone marrow transplant after chemotherapy:
You will normally receive your first dose of Neupogen at least 24 hours after your
chemotherapy and at least 24 hours after receiving your bone marrow transplant.

Neupogen is a white blood cell growth factor (granulocyte colony stimulating factor) and
belong to a group of medicines called cytokines. Growth factors are proteins that are produced
naturally in the body but they can also be made using biotechnology for use as a medicine.
Neupogen works by encouraging the bone marrow to produce more white blood cells.

You, or people caring for you, can be taught how to give subcutaneous injections so that you
can continue your treatment at home. However, you should not attempt this unless you have
been properly trained first by your health care provider.
How long will I have to take Neupogen?

A reduction in the number of white blood cells (neutropenia) can occur for several reasons
and makes your body less able to fight infection. Neupogen stimulates the bone marrow to
produce new white cells quickly.


Neupogen contains less than 1 mmol (23 mg) sodium per 0.6 mg/ml or 0.96 mg/ml dose,
i.e. essentially sodium free.

Neupogen can be used:
• to increase the number of white blood cells after treatment with chemotherapy to help
prevent infections;
• to increase the number of white blood cells after a bone marrow transplant to help prevent
• before high-dose chemotherapy to make the bone marrow produce more stem cells which
can be collected and given back to you after your treatment. These can be taken from you or
from a donor. The stem cells will then go back into the bone marrow and produce blood cells;
• to increase the number of white blood cells if you suffer from severe chronic neutropenia to
help prevent infections;
• in patients with advanced HIV infection which will help reduce the risk of infections.

You will need to take Neupogen until your white blood cell count is normal. Regular blood
tests will be taken to monitor the number of white blood cells in your body. Your doctor will
tell you how long you will need to take Neupogen.
Use in children
Neupogen is used to treat children who are receiving chemotherapy or who suffer
from severe low white blood cell count (neutropenia). The dosing in children receiving
chemotherapy is the same as for adults.
If you use more Neupogen than you should
Do not increase the dose your doctor has given you. If you think you have injected more than
you should, contact your doctor as soon as possible.
If you forget to use Neupogen

2. What you need to know before you use Neupogen
Do not use Neupogen
• if you are allergic to filgrastim or any of the other ingredients of this medicine (listed in section 6).

If you have missed an injection, or injected too little, contact your doctor as soon as possible.
Do not take a double dose to make up for any missed doses.
If you have any further questions on the use of this product, ask your doctor, nurse or

Warnings and precautions
Talk to your doctor, pharmacist or nurse before using Neupogen.

4. Possible side effects

Please tell your doctor before starting treatment if you have:
• sickle cell anaemia, as Neupogen may cause sickle cell crisis.
• an allergy to natural rubber (latex). The needle cover on the syringe may be made from a
type of natural rubber and may cause allergic reactions.
• osteoporosis (bone disease).

Please tell your doctor immediately during treatment:
• if you experience an allergic reaction including weakness, drop in blood pressure,
difficulty breathing, swelling of the face (anaphylaxis), skin rash, itchy rash (urticaria),
swelling of the face lips, mouth, tongue or throat (angioedema) and shortness of breath
• if you experience a cough, fever and difficulty breathing (dyspnoea) as this can be a sign
of Acute Respiratory Distress Syndrome (ARDS).
• if you experience kidney injury (glomerulonephritis). Kidney injury has been seen in
patients who received Neupogen. Call your doctor right away if you experience puffiness
in your face or ankles, blood in your urine or brown-coloured urine or you notice you
urinate less than usual.
• if you have any of the following or combination of the following side effects:
- swelling or puffiness, which may be associated with passing water less frequently,
difficulty breathing, abdominal swelling and feeling of fullness, and a general feeling
of tiredness. These symptoms generally develop in a rapid fashion.
These could be symptoms of a condition called “Capillary Leak Syndrome” which causes
blood to leak from the small blood vessels into your body and needs urgent medical
• if you have a combination of any of the following symptoms:
- fever, or shivering, or feeling very cold, high heart rate, confusion or disorientation,
shortness of breath, extreme pain or discomfort and clammy or sweaty skin.
These could be symptoms of a condition called “sepsis” (also called "blood poisoning"),
a severe infection with whole-body inflammatory response which can be life threatening
and needs urgent medical attention.
• if you get left upper belly (abdominal) pain, pain below the left rib cage or pain at the tip
of your shoulder, as there may be a problem with your spleen (enlargement of the spleen
(splenomegaly) or rupture of the spleen).
• if you are being treated for severe chronic neutropenia and you have blood in your urine
(haematuria). Your doctor may regularly test your urine if you experience this side effect
or if protein is found in your urine (proteinuria).

Please tell your doctor immediately during treatment with Neupogen, if you:
• have sudden signs of allergy such as rash, itching or hives on the skin, swelling of the
face, lips, tongue or other parts of the body, shortness of breath, wheezing or trouble
breathing as these could be signs of a severe allergic reaction (hypersensitivity).
• experience puffiness in your face or ankles, blood in your urine or brown-coloured urine
or you notice you urinate less than usual (glomerulonephritis).
• get left upper belly (abdominal) pain, pain below the left rib cage or at the tip of your left
shoulder (these may be symptoms of an enlarged spleen (splenomegaly), or possibly
rupture of the spleen).
• notice unusual bleeding or bruising (these may be symptoms of a decrease in blood
platelets (thrombocytopenia), with a reduced ability of your blood to clot).
Loss of response to filgrastim
If you experience a loss of response or failure to maintain a response with filgrastim treatment, your
doctor will investigate the reasons why including whether you have developed antibodies which
neutralise filgrastim’s activity.
Your doctor may want to monitor you closely, see section 4 of the package leaflet.
If you are a patient with severe chronic neutropenia, you may be at risk of developing cancer of the
blood (leukaemia, myelodysplastic syndrome (MDS)). You should talk to your doctor about your risks
of developing cancers of the blood and what testing should be done. If you develop or are likely to
develop cancers of the blood, you should not use Neupogen, unless instructed by your doctor.
If you are a stem cell donor, you must be aged between16 and 60 years.
Take special care with other products that stimulate white blood cells
Neupogen is one of a group of products that stimulate the production of white blood cells.
Your healthcare professional should always record the exact product you are using.
Other medicines and Neupogen

A common side effect of Neupogen use is pain in your muscles or bones (musculoskeletal
pain), which can be helped by taking standard pain relief medicines (analgesics). In patients
undergoing a stem cell or bone marrow transplant, Graft versus host disease (GvHD) may
occur- this is a reaction of the donor cells against the patient receiving the transplant; signs
and symptoms include rash on the palms of your hands or soles of your feet and ulcer and
sores in your mouth, gut, liver, skin, or your eyes, lungs, vagina and joints.

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

In normal stem cell donors an increase in white blood cells (leukocytosis) and a decrease of
platelets may be seen this reduces the ability of your blood to clot (thrombocytopenia), these
will be monitored by your doctor.
