1. What Neupogen is and what it is used for

Neupogen is a white blood cell growth factor (granulocyte colony-stimulating factor) belonging to a group of medicines called cytokines. Growth factors are proteins naturally produced in the body, which can be manufactured using biotechnology methods and used as medicines. Neupogen stimulates the bone marrow to produce more white blood cells.
A low number of white blood cells (neutropenia) may occur for several reasons. Neutropenia reduces the body's ability to fight infections. Neupogen stimulates the bone marrow to rapidly produce new white blood cells.
Neupogen may be used:

• to increase the number of white blood cells after chemotherapy, thereby helping to prevent the development of infections;
• to increase the number of white blood cells after bone marrow transplantation, thereby helping to prevent the development of infections;
• before high-dose chemotherapy, to stimulate the bone marrow to produce more stem cells, which can be collected from the patient and later reinfused after treatment. Stem cells can be collected from the patient themselves or from a donor. The transplanted stem cells return to the bone marrow and produce blood cells;
• to increase the number of white blood cells in patients with severe chronic neutropenia, thereby helping to prevent the development of infections;
• in patients with advanced HIV infection to reduce the risk of developing infections.

2. Important information before using Neupogen

When not to use Neupogen

• if the patient is allergic to filgrastim or any of the other ingredients of this medicine (listed in section 6.).

Warnings and precautions
Before starting treatment with Neupogen, discuss this with your doctor, pharmacist, or nurse.
Before starting treatment, inform your doctor if the patient has:

• sickle cell anaemia; Neupogen may cause a worsening of the disease.
• allergy to natural rubber (latex). The needle cap attached to the prefilled syringe is made of natural rubber and may cause an allergic reaction.
• osteoporosis (a bone disease).

Tell your doctor immediately if, during treatment with Neupogen, the patient experiences:

• sudden signs of hypersensitivity such as: rash, itching or hives, swelling of the face, lips, tongue or other parts of the body, shortness of breath, wheezing or difficulty breathing, as these may be symptoms of a severe allergic reaction (hypersensitivity),
• swelling of the face or ankles, blood in the urine or urine appearing brown, or urine output being less than usual (glomerulonephritis),
• pain in the upper left part of the abdomen, pain on the left side under the ribs, or pain at the top of the left shoulder [these may be symptoms of an enlarged spleen (splenomegaly) or possibly a ruptured spleen],
• unusual bleeding or bruising [these may be symptoms of reduced platelet count (thrombocytopenia) and reduced blood clotting ability],
• in patients with cancer and in healthy donors, symptoms of aortitis (inflammation of the aorta – the large blood vessel carrying blood from the heart to the rest of the body) have been observed rarely. Symptoms may include: fever, abdominal pain, malaise, back pain and increased inflammatory markers. If the patient experiences such symptoms, inform the doctor.

Loss of response to filgrastim
If the patient experiences a loss of response or inability to maintain response to filgrastim treatment, the doctor will investigate the reasons, including possible development of neutralizing antibodies against filgrastim.
The doctor may recommend closer monitoring of the patient; see section 4 of the leaflet.
In patients with severe chronic neutropenia, there is a risk of developing blood cancers [leukaemia, myelodysplastic syndrome (MDS)]. Discuss with the doctor the risk of blood cancers and what tests should be performed. If the patient develops blood cancers or there is a likelihood of their occurrence, Neupogen should not be used unless otherwise directed by the doctor.
Only individuals aged between 16 and 60 years may be stem cell donors.
Exercise caution when using other white blood cell-stimulating products
Neupogen belongs to a group of medicines that stimulate the production of white blood cells. The treating doctor should always clearly document the brand name of the medicine administered to the patient.
Neupogen and other medicines
Inform your doctor or pharmacist about all medicines the patient is currently taking or has recently taken, as well as any medicines the patient plans to take.
Pregnancy and breastfeeding
Studies with Neupogen have not been conducted in pregnant or breastfeeding women.
Use of Neupogen during pregnancy is not recommended.
It is important to inform the doctor:

• if the patient is pregnant or breastfeeding,
• if she suspects she may be pregnant, or
• if she plans to become pregnant.

If the patient becomes pregnant during treatment with Neupogen, she should inform her doctor.
Unless otherwise advised by the doctor, breastfeeding should be discontinued during treatment with Neupogen.
Driving and operating machinery
Neupogen may have a minor influence on the ability to drive and operate machinery. This medicine may cause dizziness. It is recommended that the patient wait and assess how they feel after taking Neupogen before driving or operating machinery.
Neupogen contains sodium
The medicine contains less than 1 mmol (23 mg) of sodium per prefilled syringe, meaning the medicine is considered "sodium-free".
Neupogen contains sorbitol
The medicine contains 50 mg of sorbitol in each ml.
Sorbitol is a source of fructose. If the patient has previously been diagnosed with hereditary fructose intolerance, a rare genetic disorder, the patient must not take this medicine. In patients with hereditary fructose intolerance, the body cannot break down the fructose contained in this medicine, which may lead to serious adverse reactions.
Inform your doctor before taking this medicine if the patient has hereditary fructose intolerance or, if the patient cannot consume sweet foods or drinks for longer periods due to nausea, vomiting or unpleasant adverse effects such as: bloating, stomach cramps or diarrhoea.

3. How to use Neupogen

This medicine should always be used exactly as prescribed by the doctor. If in doubt, consult
your doctor, nurse, or pharmacist.
How Neupogen is administered and what is the dose
Neupogen is usually given daily by injection into the tissue just under the skin (subcutaneous injection). The medicine may also be given daily by slow injection into a vein (intravenous infusion). The dose depends on the type of condition and the patient's body weight. Your doctor will inform you what dose of the medicine you should receive.
Patients undergoing bone marrow transplantation after chemotherapy:
Usually, the first dose of Neupogen will be given at least 24 hours after chemotherapy or at least 24 hours after bone marrow transplantation.
Patients or caregivers may be trained to administer subcutaneous injections so that treatment can be continued at home. Patients should not attempt this unless they have been properly trained by their doctor.
How long to use Neupogen
Neupogen should be used until the white blood cell count returns to normal. Blood tests will be performed regularly to monitor the number of white blood cells in the body. Your doctor will inform you how long you should continue Neupogen treatment.
Use in children
Neupogen is used in children receiving chemotherapy or suffering from severe neutropenia (a marked decrease in white blood cells). Dosing in children receiving chemotherapy is the same as in adults.
Use of a higher than recommended dose of Neupogen
Do not increase the dose prescribed by your doctor. If you suspect that a higher than recommended dose has been given, contact your doctor as soon as possible.
Missed dose of Neupogen
If a dose is missed or if a lower than recommended dose was given, inform your doctor as soon as possible. Do not take a double dose to make up for a missed dose.
If you have any further questions about the use of this medicine, consult your doctor, nurse, or pharmacist.

4. Possible adverse reactions

Like all medicines, this medicine can cause adverse reactions, although not everyone will experience them.
You should immediately inform your doctor if, during treatment:

• an allergic reaction occurs, including weakness, sudden drop in blood pressure, breathing difficulties, facial swelling (anaphylaxis), skin rash, itchy rash (urticaria), swelling of the face, lips, mouth, tongue or throat (angioedema), and shortness of breath (dyspnoea).
• cough, fever, and breathing problems (dyspnoea) occur, as these may be symptoms of acute respiratory distress syndrome.
• kidney damage (glomerulonephritis) occurs. Kidney damage has been observed in patients receiving Neupogen. Immediate contact with a doctor is necessary if the patient develops facial or ankle swelling, blood in the urine, or urine that is brownish in colour or passed in smaller amounts than usual.
• any of the following adverse reactions or a combination thereof occurs:
  • swelling or puffiness, which may be associated with reduced frequency of urination, difficulty breathing, abdominal swelling or a feeling of fullness, and general fatigue. These symptoms usually develop rapidly.

These may be symptoms of a condition called "capillary leak syndrome", which causes
leakage of blood from small blood vessels into the patient's body and requires
immediate medical intervention.

• any combination of the following symptoms occurs:
  • fever or chills or a sensation of intense cold, increased heart rate, confusion, disorientation, shortness of breath, severe pain or discomfort, and sticky or clammy skin. These may be symptoms of a condition called "sepsis" (also known as blood poisoning), a serious infection leading to systemic inflammation, which may be life-threatening and requires immediate medical attention.
• pain occurs in the upper left part of the abdomen, pain on the left side under the ribs, or pain at the top of the shoulder, as this may indicate spleen disorders [enlargement of the spleen (splenomegaly) or rupture of the spleen].
• blood appears in the urine (haematuria) in patients with severe chronic neutropenia. The doctor may recommend regular urine testing if such an adverse reaction occurs or if protein is present in the urine (proteinuria).

A common adverse reaction following administration of Neupogen is muscle or
bone pain (musculoskeletal pain), which can usually be relieved with commonly used
analgesic medicines. In patients undergoing stem cell or bone marrow transplantation,
graft-versus-host disease may occur – this is a reaction of donor cells against the recipient's body; symptoms and signs of this disease include rash on the palms of the hands or soles of the feet, and ulcers and pain in the oral cavity, intestines, liver, skin, eyes, lungs, vagina, and joints.
In healthy stem cell donors, an increase in white blood cell count (leukocytosis) and a decrease in platelet count, leading to reduced blood clotting ability (thrombocytopenia), have been observed; this will be monitored by the doctor.

7. Instructions for Neupogen Injection

This section provides information on how to administer Neupogen injections.
Important: Do not attempt to self-inject the medicine without prior training provided by your doctor or nursing staff.
Neupogen injection is administered into the tissue just beneath the skin. This method of administration is known as a subcutaneous injection.

Equipment needed for administering the medicine

To self-administer Neupogen subcutaneously, you will need:

• a Neupogen pre-filled syringe,
• alcohol swabs or similar cleansing wipes.

What should be done before self-administering a Neupogen subcutaneous injection?

1. Remove one pre-filled syringe from the refrigerator and leave it at room temperature for about 30 minutes, or gently hold it in your hand for several minutes. This will make the injection less uncomfortable. Do not heat Neupogen in any other way (e.g., in a microwave or hot water).
2. Do not shake the pre-filled syringe.
3. Hold the syringe in your hand and peel off the paper part of the packaging.
4. Turn the syringe over and place it in your hand.
5. Do not remove the needle cap until you are ready to administer the injection.
6. Check the expiry date on the label of the pre-filled syringe (EXP). Do not use the medicine if the last day of the month indicated on the label has passed.
7. Check the appearance of the solution. Neupogen should be a clear, colourless liquid. Do not use the medicine if discolouration, cloudiness or particles are visible.
8. Wash your hands thoroughly.
9. Gather all necessary supplies in a clean, easily accessible, and well-lit area.

How to prepare the Neupogen injection?

Before injecting Neupogen:

1. To avoid bending the needle, safely hold the glass barrel of the pre-filled syringe; gently remove the needle cap without twisting, as shown in Figures 1 and 2.
2. Do not touch the needle or press the plunger.
3. Small air bubbles may be visible in the pre-filled sy游戏副本. Removing these air bubbles before injection is not necessary. Injecting a solution containing air bubbles is harmless.
4. The pre-filled syringe is now ready for use.

Where should Neupogen be self-injected?

The best sites for self-injection are the upper thighs
and the abdomen. If another person is administering the injection,
the upper back area of the arms may also be used.
You may change the injection site if the previous site becomes red or painful.

How to self-administer the Neupogen injection?

1. Disinfect the skin using an alcohol swab and grasp (but do not squeeze) a fold of skin between your thumb and index finger.
2. Insert the needle fully into the skin, as demonstrated by your nurse or doctor.
3. Push the plunger steadily while maintaining the skin fold between your fingers, injecting the medicine until the syringe is completely empty.
4. Remove the needle and release the skin fold.
5. If a drop of blood appears at the injection site, gently wipe it with a swab or gauze. Do not rub the skin at the injection site. If necessary, a bandage may be applied to the injection site.
6. Each syringe is for single use only. Do not use any Neupogen remaining in the syringe.

Important: If you have any doubts, do not hesitate to contact your doctor or nursing staff for assistance.

Disposal of used syringes

• Do not recap used needles, as this may result in accidental needle-stick injury.
• Store used syringes out of sight and reach of children.
• Do not dispose of used syringes in household waste containers. Ask your pharmacist how to properly dispose of used or unwanted syringes.

Information intended exclusively for healthcare professionals:

When used as a concentrate for solution for infusion, Neupogen should be diluted in 20 ml of 5% glucose solution. Detailed information is available in the Summary of Product Characteristics.
