1. WHAT GAMMANORM IS AND WHAT IT IS USED FOR
Gammanorm is an immunoglobulin and contains antibodies against bacteria and viruses. Antibodies
protect the body and increase its resistance to infections. The purpose of this
treatment is to attain normal antibody levels.
Gammanorm is used as replacement therapy in adults and children to treat primary immunodeficiency
syndromes such as:
- congenital agammaglobulinaemia and hypogammaglobulinaemia
- common variable immunodeficiency (CVID)
- severe combined immunodeficiency
- IgG subclass deficiencies with recurrent infections
- myeloma or chronic lymphatic leukaemia with severe secondary
hypogammaglobulinaemia and recurrent infections.
Using other medicines
2. BEFORE YOU USE GAMMANORM
Inform your doctor or pharmacist if you are taking, or have recently taken any other
medicines, even over-the-counter ones, or if you have received a vaccination in the
last three months.
Gammanorm may weaken the effect of all vaccines containing live viruses such as
measles, rubella, mumps, and chicken pox. Following treatment with Gammanorm,
three months should have elapsed before you are vaccinated with any of these
vaccines. Where measles vaccine is concerned, you may need to wait up to a year
following treatment with Gammanorm. It is therefore important that the doctor
carrying out the vaccination is aware that you are having, or have had treatment
Inform your doctor that you are taking immunoglobulin when you give a blood
sample, as this treatment may affect the results.
Do not use Gammanorm
- if you are hypersensitive to human normal immunoglobulin or any of the other ingredients of
- intravenously (Gammanorm must not be administered into a vein).
- intramuscularly (into a muscle) by yourself. Gammanorm must not be given into a muscle if you have
any bleeding disorders.
Pregnancy and breast-feeding
Take special care with Gammanorm
- Tell your doctor if you have any other illnesses.
- If Gammanorm is accidentally administered into a blood vessel you could develop shock.
- True hypersensitivity reactions are rare. They can particularly occur in the very rare cases of IgA
deficiency with anti-IgA antibodies and these patients should be treated with caution.
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 the 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 the 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 medicinal product contains 4.35 mmol (or 100 mg) sodium per dose (40 ml). Please take this into
consideration if you are on a controlled sodium diet.
There is limited experience of usage of Gammanorm during pregnancy and breast-feeding. You should
therefore consult your doctor before use of Gammanorm when you are pregnant or breast-feeding.

Important information about some of the ingredients of Gammanorm
3. HOW TO USE GAMMANORM
The treatment will be started off by your doctor who will ensure that you receive training and precise
information on using the pump, injection technique, keeping a treatment diary, and what action to
take in the event of serious side effects. As soon as you are able to treat yourself, and if no side effects
have arisen during treatment, your doctor may allow you to continue treatment at home.
The dosage and infusion speed will be determined by your doctor, who will adapt the dose especially
for you. Always follow your doctor’s instructions.
This product should be administered subcutaneously (under the skin). In special cases where
Gammanorm cannot be given subcutaneously, it may be administered intramuscularly (into muscle).
An intramuscular injection must be given by a doctor or nurse.
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), hepatitis B virus and hepatitis C virus.
The measures taken may be of limited value against non-enveloped 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.
Note: Every time you receive a dose of Gammanorm you should record
the name and batch number of the product in order to maintain a record of the batch used.
Always use Gammanorm exactly as your doctor has told you. You should check with your doctor if
you are not sure.
The product should be at room or body temperature prior to use.
The solution should be clear or slightly opalescent and colourless or pale yellow or light brown. Do
not use solution that is cloudy, contains particles, or has deposits.

• To withdraw Gammanorm, use a sterile syringe and needle or transfer device (e.g. Minispike® or
Medimop® vial adapter).
The following information is intended for medical or healthcare
Inject air into the vial that is equivalent to the amount of Gammanorm
to be withdrawn. Then withdraw Gammanorm from the vial. If
multiple vials are required to achieve the desired dose, repeat this
step (Fig. 1).
• Follow the manufacturer’s instructions for preparing the syringe driver. Prime the administration
tubing to ensure that no air is left in the tubing by filling the tubing/needle with Gammanorm.

If you forget to use Gammanorm
If you forget to inject one dose of Gammanorm do not use a double dose or multiple doses at the
same time to make up for the forgotten dose. Instead inject one dose as soon as possible, then go on
injecting Gammanorm as prescribed by your doctor.
Grasp the skin between two fingers (Fig. 3).
Insert the needle under the skin (Fig. 4).
Gammanorm must not be injected into a blood vessel. To test that no
blood vessel has been accidentally hit, gently pull back on the syringe
plunger and look to see if any blood is flowing back into the tubing
(Fig. 5). If you see any blood, remove and discard the needle and tubing,
gently applying pressure with cotton wool or gauze to where the needle
was inserted. Repeat priming and needle insertion steps using a new
needle, tubing and a new injection site.
Secure the needle in place by applying sterile gauze or a transparent
dressing (Fig. 6).
Inject Gammanorm following the manufacturer’s instructions for the
syringe driver (Fig. 7).
