What is it and how is it used?
What Privigen is
Privigen is a ready-to-use solution for infusion. The solution contains special proteins, isolated from human blood plasma. These proteins belong to the class of "immunoglobulins", also called antibodies.
How Privigen works
Antibodies are usually produced by our immune system and help the body to fight infections. Certain diseases can cause severe disturbance of the immune system. Because of this, you may not have enough of your own antibodies or you may need additional antibodies. The antibodies which are given to you by Privigen can complement your own antibodies or substitute missing antibodies. The antibodies in Privigen are isolated from human blood plasma. Therefore they work exactly as if they were your own antibodies.
Privigen can also reduce the symptoms in certain inflammatory disorders. In these cases Privigen is regulating the malfunctioning immune system. However, these effects are not fully understood.
What Privigen is used for
Privigen is used in three different situations:
A) Treatment of patients with too few antibodies (replacement therapy). There are three groups:
1. Patients with an inborn lack of antibodies (primary immunodeficiency syndromes (PID)) such as: - congenital agammaglobulinaemia or hypogammaglobulinaemia, - common variable immunodeficiency, - severe combined immunodeficiency,- Wiskott Aldrich syndrome.
2. Patients with certain kinds of blood cancer which lead to a lack of antibody production and recurrent infections such as: - myeloma, - chronic lymphocytic leukaemia with severe secondary hypogammaglobulinaemia.
3. Children who suffer from inborn AIDS (Acquired Immunodeficiency Syndrome) and recurrent infections.
B) Treatment of patients with certain inflammatory disorders (immunomodulation). There are threegroups:
1. Patients who do not have enough blood platelets (immune thrombocytopenic purpura (ITP)) and - who are at high risk of bleeding, - will have a surgery in the near future.
2. Patients with Guillain-Barré syndrome. This is an acute disease that is characterised by inflammation of the peripheral nerves that causes severe muscle weakness mainly in the legs and upper limbs.
3. Patients with Kawasaki disease. This is an acute disease of primarily young children characterised by an inflammation of the blood vessels throughout the body.
C) Treatment or prevention of infections after a bone marrow transplantation (allogeneic bonemarrow transplantation).
What do you have to consider before using it?
Please read this section carefully. The information given should be taken into consideration by you and your doctor before you receive Privigen.
Privigen must not be used
If you are allergic hypersensitive to human immunoglobulins, to any other ingredient of Privigen for a complete list of ingredients see section 6 of this leaflet. Please tell your doctor or health care professional prior to treatment about any medicine or food which you have not well tolerated earlier. If you have antibodies against immunoglobulins of the type IgA in your blood. This is very rare and may occur if you do not have enough immunoglobulins of the type IgA in your blood. Please tell your doctor or health care professional prior to treatment if you have an immunoglobulin type IgA deficiency. If you have too much of the amino acid proline in your blood hyperprolinaemia. This is an extremely rare disorder. Only a few families with this disease are known worldwide. Please tell your doctor or health care professional prior to treatment if you have too much proline in your blood.
Take special care with Privigen
The risk of having certain side effects may be increased in the following circumstances you are overweight, you are elderly, you have diabetes, you have been bedridden for a longer time, you have or have already had problems with your blood vessels vascular diseases or blockage of a vessel, you have or have already had kidney problems, you have a high blood pressure, you blood volume is too low hypovolaemia, you suffer from a disease which causes your blood to thicken, you suffer from an increased tendency for blood clotting thrombophilia,
you suffer from a condition that causes low antibody levels in your blood hypogammaglobulinaemia or agammaglobulinaemia, you suffer from a kidney disease, you are taking medicines that can damage your kidneys nephrotoxic medicines, you are receiving Privigen for the first time or after a long break in treatment e.g. several months. Please tell your doctor or health care professional prior to treatment if at least one of these circumstances applies to you. Your doctor will then choose the right intravenous immunoglobulin for you and will take special precautions. Although Privigen does not contain sugar, it may be diluted with a special sugar solution 5 glucose, which could affect your blood sugar level.
You may be allergic hypersensitive to immunoglobulins antibodies without knowing it. This may occur even if you have previously received human immunoglobulins and had tolerated them well. It may happen particularly if you do not have enough immunoglobulins of the type IgA in your blood. In these rare cases allergic reactions such as a sudden fall in blood pressure or shock may occur. If you notice such reactions during the infusion of Privigen, please tell your doctor immediately. He will decide whether to slow down the infusion rate or whether to abort the infusion completely.
For your personal safety the treatment with Privigen will take place under the supervision of your doctor or health care professional. You will usually be observed during the whole infusion and for at least 20 minutes thereafter. In certain circumstances, special precautions may be necessary. Examples of such circumstances are:
- you are receiving Privigen at a high infusion rate or
- you are receiving Privigen for the first time or after a long break in treatment (e.g. several months).
In these cases you will be closely observed during the whole infusion and for at least 1 hour thereafter.
Information on the starting material of Privigen
Privigen 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 products 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 and other types of infections.
The measures taken are considered effective for enveloped viruses such as human immunodeficiency virus (HIV), hepatitis B virus and hepatitis C virus, and for the non-enveloped hepatitis A and B19 viruses.
Immunoglobulins like Privigen have not been associated with hepatitis A or B19 infections. This is possibly because antibodies against these infections are also present in immunoglobulins. These antibodies may help prevent hepatitis A or B19 infections.
It is strongly recommended that every time you receive a dose of Privigen the name and batch number of the product are recorded in order to maintain a record of the batches used.
Taking Privigen with other medicines
Please tell your doctor or health care 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.
After receiving Privigen, the efficacy of certain vaccinations may be impaired. Affected are vaccinations with live attenuated virus vaccines such as vaccinations against measles, mumps, rubella and varicella. Such vaccinations should be postponed for at least 3 months after the last infusion of Privigen. In the case of measles vaccinations the impairment may persist for up to one year. Therefore your vaccinating doctor should check the efficacy of the measles vaccination.
Please tell your vaccinating doctor prior to a vaccination about your treatment with Privigen.
After receiving Privigen, the results of certain blood tests (serological tests) may be impaired for a certain time.
Please tell your doctor about your treatment with Privigen prior to any blood test.
Pregnancy and breast-feeding
Please tell your doctor or health care professional if you are pregnant or breast-feeding. Your doctor will decide whether you can receive Privigen during your pregnancy or while you are breast-feeding.
The use of Privigen in pregnant or breast-feeding women has not been studied separately. Nevertheless, medicines containing antibodies have been used in pregnant or breast-feeding women. The long-time experience showed that no harmful effects on the course of the pregnancy or the newborn are to be expected.
If you receive Privigen while you are breast-feeding the antibodies in this medicine will also be found in the breast milk. Thus also your baby can receive the protecting antibodies.
Driving and using machines
No effects of Privigen on the ability to drive and use machines are expected.
How is it used?
Privigen is usually administered by your doctor or health care professional. Privigen is intended solely for the infusion into a vein intravenous infusion. Your doctor decides how much Privigen you will receive. The amount depends on your illness, your present condition and your body weight. At the beginning of the infusion you will receive Privigen at a slow infusion rate. If you tolerate this well your doctor can gradually increase the infusion rate.
If you receive more Privigen than you should
Privigen is usually administered under medical supervision only. Overdose is therefore very unlikely to occur. If, in spite of this, you receive more Privigen than you should, your blood may become too thick (hyperviscous). This may happen particularly if you are a patient at risk, for example if you are elderly or if you suffer from a kidney disease.
What are possible side effects?
Like all medicines, Privigen can cause side effects, although not everybody gets them.
You may be allergic hypersensitive to immunoglobulins antibodies and allergic reactions such as a sudden fall in blood pressure or shock may occur. If you notice such reactions during the infusion of Privigen, please tell your doctor immediately. Please see also section 2 of this leaflet about the risk of allergic reactions.
Possible side effects may be reduced or even avoided by infusing Privigen at a slow infusion rate.
The general experience with immunoglobulin preparations showed that the following side effects may occur headache, chills, fever, vomiting, mild hypersensitivity reactions allergic reactions, nausea, pain in the joints arthralgia, low blood pressure, moderate low back pain.
In rare and isolated cases, the following side effects have also been reported with immunoglobulin preparations temporary non-infectious meningitis reversible aseptic meningitis, transient skin reactions, increase in blood creatinine level, acute renal failure, sudden fall in blood pressure, severe hypersensitivity reactions anaphylactic shock, even when you have shown no hypersensitivity on previous infusions, formation of blood clots which may be carried off in the blood circulation thromboembolic reactions and which may result e.g. in myocardial infarction, stroke, lung vein blockage pulmonary embolism, deep vein thrombosis, transient decrease of red blood cells reversible haemolytic anaemiahaemolysis.
Three clinical studies with Privigen were conducted. In these studies the following side effects have been observed.
The following side effects were common in more than 1 in 100, but less than 1 in 10 infusions headache, vomiting, upset stomach nausea, back pain, chills, tiredness fatigue, fever.
The following side effects were uncommon (in more than 1 in 1000, but less than 1 in 100 infusions): - abnormal awareness of heartbeat,
- temporary lowering of red blood cell count,
- irregularity of red blood cell shape (microscopic finding),
dizziness, head discomfort, sleepiness, shiver tremor, breathlessness, blisters in mouth and throat, painful breathing, throat tightness, diarrhoea, upper stomach pain, protein in the urine on testing, itching, skin disorder, night sweats, hives rash, pain including neck pain, pain in extremity, chest pain, muscle pain, pain and stiffness of muscles and bones muscle spasms, flushing, high or low blood pressure, weakness, flu-like illness, injection site pain, mild jaundice.
Routine laboratory tests may uncommonly reveal changes to liver or kidney functions as well as changes in blood count.
Such side effects may occur even when you have previously received human immunoglobulins (antibodies) and had tolerated them well.
Please tell your doctor or health care professional
- if any of the side effects gets serious or
- if you notice any side effects not listed in this leaflet.

Method of administration
- Human normal immunoglobulin should be infused intravenously. The initial infusion rate is 0.3 ml/kg bw/hr. If well tolerated, the rate of administration may gradually be increased to 4.8 ml/kg bw/hr.
- In PID patients who have tolerated the infusion rate of 4.8 ml/kg bw/hr well, the rate may be further increased gradually to a maximum of 7.2 ml/kg bw/hr.
- If dilution prior to infusion is desired, Privigen may be diluted with 5% glucose solution to a final concentration of 50 mg/ml (5%). Special precautions
- In case of adverse reaction, either the rate of administration must be reduced or the infusion stopped.
- It is strongly recommended that every time Privigen is administered to a patient, the name and batch number of the product are recorded in order to maintain a link between the patient and the batch of the product.
This medicinal product must not be mixed with other medicinal products
Special precautions for disposal and other handling
- The product should be at room or body temperature before use. A vented infusion line should be used for the administration of Privigen. Always pierce the stopper at its centre, within the marked area.
- The solution should be clear or slightly opalescent. Do not use solutions that are cloudy or have particulate matter.
- If dilution is desired, 5% glucose solution is recommended. For obtaining an immunoglobulin solution of 50 mg/ml (5%), Privigen 100mg/ml (10%) should be diluted with an equal volume of the glucose solution. Aseptic technique must be strictly observed during the dilution of Privigen.
- Once the vial has been entered under aseptic conditions, its contents should be used promptly. Because the solution contains no preservative, Privigen should be infused as soon as possible.
- Any unused product or waste material should be disposed of in accordance with local requirements.
