1. What Panzyga is and what it is used for

What Panzyga is

Panzyga is a human normal immunoglobulin (IgG) solution (i.e. solution of human antibodies) for intravenous administration (i.e. infusion into a vein). Immunoglobulins are normal constituents of the human blood and support the immune defence of your body. Panzyga contains all IgG which are present in the human blood of healthy people. Adequate doses of Panzyga may restore abnormally low IgG levels to the normal range.

Panzyga has a broad spectrum of antibodies against various infectious agents.

What Panzyga is used for

Panzyga is used for the treatment of children and adults (replacement therapy). There are 4 groups of patients where replacement therapy is used:

  • Patients with inborn deficiency of antibodies (primary immunodeficiency syndromes, such as: congenital agammaglobulinaemia and hypogammaglobulinaemia, common variable immunodeficiency, severe combined immunodeficiencies)
  • Patients with diseases of the blood that lead to a lack of antibodies and to recurrent infections (Myeloma or chronic lymphatic leukaemia with severe secondary hypogammaglobulinaemia and recurrent infections)
  • Patients who have low levels of immunoglobulins after the transplantation of stem cells
  • Patients with congenital AIDS who have repeated bacterial infections

Panzyga can be further used in the treatment of inflammatory disorders (immunomodulation). There are 5 groups of patients:

  • In patients with immune thrombocytopenia (ITP), a condition where the platelets get destroyed and are therefore reduced in number, and who have a high risk of bleeding or need to correct the platelet count prior to surgery
  • In patients with Kawasaki disease, a condition that leads to inflammation of various organs
  • In patients with Guillain Barré syndrome, a condition that leads to inflammation of certain parts of the nervous system

2. What you need to know before you use Panzyga

Do NOT use Panzyga:

  • if you are allergic to human normal immunoglobulin or any of the other ingredients contained in Panzyga (listed in section 6).
  • if you have a deficiency of immunoglobulin A (IgA deficiency) and if you have developed antibodies against immunoglobulins of the type IgA.

Warnings and precautions

Talk to your doctor or pharmacist before using Panzyga.

Certain adverse reactions may occur more frequently:

  • in case of high rate of infusion
  • when you receive Panzyga for the first time or, in rare cases, when there has been a long interval since the previous infusion.

In the case of an adverse reaction, your doctor will either reduce the rate of administration or stop the infusion. The treatment of the adverse event required will depend on the nature and severity of the adverse event.

Circumstances and conditions increasing the risk of having side effects

  • If you had kidney problems in the past or if you have certain risk factors like diabetes, overweight, or age over 65, Panzyga should be administered as slow as possible because cases of acute kidney failure have been reported in patients with such risk factors. Tell your doctor, even when any of the above-mentioned circumstances had happened to you in the past.
  • Thromboembolic events such as heart attack, stroke, and obstructions of a deep vein for example in the calves or of a blood vessel in the lung may occur very rarely after administration of Panzyga. These types of events occur more commonly in patients with risk factors, such as obesity, advanced age, high blood pressure, diabetes, previous occurrences of such events, prolonged periods of immobilisations, and intake of certain hormones (e.g. the pill). Ensure a balanced fluid intake; moreover Panzyga should be administered as slow as possible.
  • Allergic reactions are rare, but can induce an anaphylactic shock, even in patients who had tolerated the previous treatments.
  • Strong headaches and neck stiffness may rarely occur several hours to 2 days following Panzyga treatment.
  • Patients with blood group A, B or AB as well as patients with certain inflammatory conditions have a higher risk of red blood cells being destroyed by the administered immunoglobulins (called haemolysis).

Effects on blood tests

Panzyga contains a wide variety of different antibodies, some of which can affect blood tests. If you have a blood test after receiving Panzyga, please inform the person taking your blood or your doctor that you have received the human normal immunoglobulin.

Virus safety

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
  • testing of each donation and pools of plasma for signs of virus/infections
  • steps included by the manufacturers 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 encapsulated viruses such as human immunodeficiency virus (HIV), hepatitis B virus and hepatitis C virus and for the non-encapsulated viruses such as hepatitis A virus and parvovirus B19.

Immunoglobulins have not been associated with hepatitis A or parvovirus B19 infections possibly because the antibodies against these infections, which are contained in the product, are protective.

It is strongly recommended that every time you receive a dose of Panzyga the name and batch number of the product are recorded in order to maintain a record of the batches used.

Children and adolescents

There are no specific or additional warnings or precautions applicable for children and adolescents.

Other medicines and Panzyga

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription, or if you have received a vaccination in the last three months.

Panzyga may impair the effect of live attenuated virus vaccines such as

  • measles
  • rubella
  • mumps
  • varicella.

After administration of this product, an interval of 3 months should elapse before vaccination with live attenuated virus vaccines. In the case of measles, this impairment may persist for up to 1 year.

Pregnancy, breast-feeding and fertility

If you are pregnant or breast-feeding, think you may be pregnant or are planning to become pregnant, ask your doctor or pharmacist if you can get or continue with Panzyga.

Driving and using machines

The ability to drive and operate machines may be impaired by some adverse reactions associated with Panzyga. Patients who experience adverse reactions during treatment should wait for these to resolve before driving or operating machines.

Panzyga contains sodium

This medicinal product contains not more than 0.03 mmol (or 0.69 mg) sodium per ml. To be taken into consideration by patients on a controlled sodium diet.

3. How to use Panzyga

Your doctor will decide if you need Panzyga and at what dose. Panzyga is administered as an intravenous infusion (infusion into a vein) by healthcare personnel. The dose and dosage regimen is dependent on the indication and may need to be individualised for each patient.

If you have any further questions on the use of this product, ask your doctor or pharmacist.
