What is Lonquex used for

Lonquex is used following chemotherapy to help fight infection.

Some chemotherapy will reduce the number of neutrophils in your body. Although Lonquex is not a treatment for cancer, it does help the body to make new neutrophils and this may 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

Lonquex contains the active substance lipegfilgrastim. Lipegfilgrastim is a long-acting modified protein produced by biotechnology in bacteria called Escherichia coli. It belongs to a group of proteins called cytokines and is similar to a natural protein (granulocyte-colony stimulating factor [G-CSF]) produced by your own body.

Lipegfilgrastim stimulates the bone narrow (the tissue where new blood cells are made) to produce more white blood cells. White blood cells are important as they help your body fight infection. These cells are very sensitive to the effects of chemotherapy which can cause the number of these cells in your body to decrease. If white blood cells fall to a low level, there may not be enough left in the body to fight bacteria and you may have an increased risk of infection.

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.

How to use it

Lonquex is given by injection using a prefilled syringe, usually into the tissues just below the skin. This is called a subcutaneous injection and it is a simple procedure.

It is important that you do not try to give yourself the injection unless you have received special training from your doctor or nurse.

If you are not sure about giving yourself the injection or you have any questions, please ask your doctor or nurse for help.

The recommended dose is one prefilled syringe (6 mg lipegfilgrastim) ONCE PER CHEMOTHERAPY CYCLE. This medicine should be given approximately 24 hours after your last dose of chemotherapy at the end of each chemotherapy cycle.

To give yourself an injection into the tissue under the skin you will need:

a pre-filled syringe of Lonquex

an alcohol wipe

a piece of gauze bandage or sterile gauze swab

Instructions for Injecting Lonquex

What you should do before your injection:

Take the medicine out of the refrigerator.

Open the blister and take the pre-filled syringe out of the blister. Do not pick up the pre-filled syringe by the plunger or needle cover. This will damage the safety device.

Check the expiry date on the pre-filled syringe label (EXP). Do not use if the date has passed the last day of the month shown.

Check the appearance of Lonquex. It must be a clear and colorless liquid. If there are particles in it or if it is cloudy, you must not use it.

Do not shake Lonquex vigorously as this may affect its activity.

For a more comfortable injection, let the pre-filled injection stand for 30 minutes to reach room temperature (not above 25°C) or hold the pre-filled syringe gently in your hand for a few minutes. Do not warm Lonquex in any other way (for example, do NOT warm it in a microwave or in hot water).

Do NOT remove the needle cover from the syringe until you are ready to inject.

Find a comfortable, well-lit place. Place everything where you can reach for it (the Lonquex pre-filled syringe, an alcohol wipe and a piece of gauze bandage or a sterile gauze swab.

Wash your hands thoroughly.

How to prepare for your injection

Before you give yourself a Lonquex injection, you must do the following:

Hold the syringe and gently remove the cover from the needle without twisting. Pull straight. Do not touch the needle or push the plunger.

You may notice small air bubbles in the pre-filled syringe. If there are air bubbles present, gently tap the syringe with your fingers until the air bubbles rise to the top of the syringe. With the syringe pointing upwards, expel all air form the syringe by pushing the plunger slowly upwards.

You can now use the pre-filled syringe.

Keep pre-filled syringes out of the sight and reach of children.

Where your injection should be given

The most suitable places to inject yourself are:

the top of your thighs.

the abdomen avoiding the skin directly surrounding the navel.

If someone else is injecting you, they can also use the back and side of your upper arms.

How you should inject yourself

Disinfect the injection site on the skin by using an alcohol wipe and pinch the skin between your thumb and forefinger, without squeezing it.

Put the needle fully into the skin as shown by your nurse or doctor. The angle between the syringe and skin should not be too narrow (at least 45°).

Pull slightly on the plunger to check that a blood vessel has not been punctured. If you see blood in the syringe, remove the needle and re-insert it in another place.

Inject the liquid into the tissue slowly and evenly, always keeping your skin pinched.

Push the plunger as far as it will go to inject all the liquid. While the plunger is still pressed all the way down, remove the needle from the skin. Then release the plunger. The safety device will be activated immediately. The entire needle and syringe will be drawn back automatically and covered so that you cannot prick yourself.

Press the injection site with a piece of gauze bandage or a sterile gauze swab for several seconds.

Each pre-filled syringe is for single use only.

If you have any problems, please ask your doctor or pharmacist for help and advice.

How you should dispose of used syringes

Do not put the cover back on used needles.

Put used syringes into the puncture-proof container and keep this container out of the sight and reach of children.

Dispose of the full puncture-proof container as instructed by your doctor, nurse or pharmacist.

Never put the syringes that you have used back into your normal household rubbish bin.

Allergic reactions such as skin rash, raised itchy areas of skin and serious allergic reactions with weakness, drop in blood pressure, difficulty breathing and swelling of the face have been reported uncommonly (may affect up to 1 in 100 people).

It is important to contact your doctor immediately if you experience pain in the upper left side of the abdomen or left shoulder pain since this may relate to a problem with your spleen.

Cough, fever and difficult or painful breathing can be signs of uncommon (may affect up to 1 in 100 people) serious pulmonary side effects, such as pneumonia and acute respiratory distress syndrome, which may be fatal. If you have a fever or any of these symptoms, it is important to contact your doctor immediately.

It is important to contact your doctor immediately if you have any of the following symptoms: 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 reported with other medicines similar to Lonquex called "capillary leak syndrome", which causes blood to leak from the small blood vessels into your body and needs urgent medical attention.

Other side effects

Very common (may affect more than 1 in 10 people):

Musculoskeletal pains such as bone pain and pain in the joints, muscles, limbs, chest, neck or back. Your doctor will tell you what you can take to ease the bone pain.

Common (may affect up to 1 in 10 people):

Reduction in blood platelets, which increases risk of bleeding or bruising

Low blood levels of potassium, which can cause muscle weakness, twitching or abnormal heart rhythm

Chest pain

Uncommon (may affect up to 1 in 100 people):

Rise in white blood cells

Local reactions at the injection site, such as pain or hardening

Some changes may occur in your blood, but these will be detected by routine blood tests.

Plum-colored raised painful sores on the limbs and sometimes the face and neck with fever (Sweet's syndrome)
