What Hizentra is
Hizentra belongs to the class of medicines called human normal immunoglobulins. Immunoglobulins are also known as antibodies and are blood proteins that help your body to fight infections.
How Hizentra works
Hizentra contains immunoglobulins that have been prepared from the blood of healthy people. The medicine works in exactly the same way as the immunoglobulins naturally present in your blood.
What Hizentra is used for
Hizentra is used to raise abnormally low immunoglobulin levels in your blood to normal levels (replacement therapy). The medicine is used in two different situations:
1. Treatment of adults and children who are born with a reduced ability or inability to produce immunoglobulins (primary immunodeficiencies). This includes conditions such as:
- low immunoglobulin levels (hypogammaglobulinaemia) or absence of immunoglobulins (agammaglobulinaemia) in the blood
- combination of low immunoglobulin levels, frequent infections and inability to produce adequate amounts of antibodies after vaccination (common variable immunodeficiency)
- combination of low level or absence of immunoglobulins and absence or non-functional immune cells (severe combined immunodeficiency)
- lack of certain immunoglobulin G subclasses causing recurrent infections.
2. Treatment of adults and children with certain kinds of blood cancer (such as myeloma or chronic lymphocytic leukaemia) which lead to severely low immunoglobulin levels in the blood and cause recurrent infections.

Do NOT inject Hizentra:
if you are allergic hypersensitive to human immunoglobulins, polysorbate 80 or L-proline. Tell your doctor or healthcare professional prior to treatment if you have experienced an intolerance against one of these components earlier. if you suffer from hyperprolinaemia a genetic disorder causing high levels of the amino acid proline in the blood. into a blood vessel.
Take special care with Hizentra
You may be allergic (hypersensitive) to immunoglobulins without knowing it. However, true allergic reactions are rare. They may occur even if you received human immunoglobulins previously and tolerated them well. It may happen particularly if you do not have enough of the immunoglobulin type A (IgA) in your blood (IgA deficiency). In these rare cases allergic reactions such as a sudden fall in blood pressure or shock may occur (e.g. you may feel light-headed, dizzy, faint on standing, cold in the hands and feet, sense an abnormal heart beat or chest pain, or have blurred vision). - If you notice such signs during the infusion of Hizentra, tell your doctor immediately. He or she will decide whether to slow down the infusion rate or whether to stop the infusion completely.
Your healthcare professional will avoid potential complications by ensuring:
- that you are not sensitive to human normal immunoglobulin.
The medicine must be infused slowly at first. The recommended infusion rate given under section 3 ?How to use Hizentra? must be closely followed.
- that you are carefully monitored for any symptoms throughout the infusion period, especially if:
- you receive human normal immunoglobulin for the first time
- you have switched from a different medicine
- there has been a long interval (more than eight weeks) since the previous infusion. In these cases, it is recommended that you are monitored during the first infusion and for an hour afterwards. If the points above do not apply for you it is recommended that you are observed for at least 20 minutes after administration.
After receiving Hizentra, the results of certain blood tests (serological tests) may be impaired for a certain time.
- Tell your doctor about your treatment with Hizentra prior to any blood test.
Information on what Hizentra is made of
Hizentra is made from human blood plasma (this is the liquid part of the blood). When medicines are made from human blood or plasma, certain measures are put in place to prevent infections being passed on to patients. These include:
- careful selection of blood and plasma donors to make sure those at risk of carrying infections are excluded, and
- the testing of each donation and pools of plasma for signs of virus/infections. Manufacturers of these medicines also include steps in the processing of the blood or plasma that can inactivate or remove viruses. Despite these measures, when medicines prepared from human blood or plasma are administered, the possibility of passing on infection cannot be totally excluded. This also applies to any unknown or emerging viruses or other types of infections.
The measures taken are considered effective for enveloped viruses such as human immunodeficiency virus (HIV, the AIDS virus), hepatitis B virus and hepatitis C virus (liver inflammation), and for the non-enveloped hepatitis A virus and parvovirus B19.
- It is recommended that every time you take Hizentra the following data are recorded in your treatment diary:
- the date of administration,
- the batch number of the medicine, and
- the injected volume, flow rate, the number and location of injection sites.
Taking other medicines
Tell your doctor or healthcare professional prior to treatment if you are currently taking any other medicines or if you have recently taken any other medicines. This also includes non-prescription medicines.
You must not mix other medicines with Hizentra.
Hizentra may impair the effect of some live virus vaccines such as measles, rubella, mumps and chicken pox. Therefore, after receiving these medicines you may have to wait up to 3 months before receiving your live-attenuated vaccine. In the case of measles vaccinations the impairment may persist for up to 1 year.
Therefore your vaccinating doctor should check the efficacy of the measles vaccination. - Tell your vaccinating doctor prior to a vaccination about your treatment with Hizentra.
Pregnancy and breast-feeding
Tell your doctor or healthcare professional if you are pregnant, plan to become pregnant or are breast-feeding. Your doctor will decide whether you can receive Hizentra during your pregnancy or while you are breast-feeding.
No clinical studies have been performed with Hizentra in pregnant women. However, medicines that contain immunoglobulins have been used in pregnant or breast-feeding women for years, and no harmful effects on the course of pregnancy or on the baby have been observed.
If you are breast-feeding and receive Hizentra, the immunoglobulins of the medicine can also be found in the breast milk. Therefore, your baby may be protected from certain infections.
Driving and using machines
No effects of Hizentra on the ability to drive and use machines are expected.
Important information about some of the ingredients of Hizentra
Hizentra contains proline and you must not take it if you suffer from hyperprolinaemia (see also section 2 ?Before you use Hizentra?). Please tell your doctor prior to treatment.

Always use Hizentra exactly as your doctor has told you. Check with your doctor if you are not sure.
Your doctor will calculate the correct dose for you taking into account your weight and response to treatment.
Your doctor will determine whether you need a loading dose (for adults and children) of at least 1 to 2.5 ml/kg of body weight divided over several days. Following this, maintenance doses may be given,
usually weekly, to reach a cumulative monthly dose of about 2 to 4 ml/kg of body weight. Your healthcare professional may adjust the dose based on your response to the treatment.
Method of administration
In case of home treatment, this will be initiated by a healthcare professional experienced in the treatment of immunodeficiency and in the guidance of patients for home treatment.

- The recommended initial infusion rate is up to 15 ml/hour/site. If well-tolerated, the infusion rate can then gradually be increased to 25 ml/hour/site.
- You may use up to 4 injections sites simultaneously, provided that the maximum infusion rate for all sites combined does not exceed 50 ml/hour. Injection sites should be at least 5 cm apart.
