Human normal immunoglobulin (IVIg)

1. What Flebogamma DIF is and what it is used for

What Flebogamma DIF is

Phlebogamma DIF contains human normal immunoglobulin, a highly purified protein derived from human plasma (part of the blood from blood donors). It belongs to a group of medicines called immunoglobulin for intravenous use. These are used to treat conditions where the body’s defenses against infection do not work properly.

What Flebogamma DIF is used for

Treatment of adults, children, and adolescents (2-18 years) who do not have enough antibodies (Flebogamma DIF is used as substitution therapy ). There are TV groups:

  • Patients with primary immunodeficiency syndrome (PID) with congenital deficiency of antibodies (group 1).
  • Patients with secondary immunodeficiency (SID) with severe or recurrent infection, ineffective antimicrobial treatment, and either inability to respond to a specific antigen, so-called PSAF ( proven specific antibody failure ) * or IgG levels in serum <4 g / l (group 2).

* PDF = inability to obtain at least one doubled IgG antibody titer against pneumococcal polysaccharide and polypeptide antigen vaccines.

Treatment of adults, children, and adolescents (2–18 years) with certain autoimmune diseases (immune modulation). There are five groups:

  • Primary immune thrombocytopenia (ITP) is a condition in which the number of platelets in the blood has decreased sharply. Platelets play an important role in blood clotting and patients who do not have enough platelets are at high risk for unwanted bleeding and bruising. The drug is also used in patients at high risk of bleeding or who will be operated on shortly.
  • Guillain-Barré syndrome in which the immune system damages the nerves and prevents them from functioning properly.
  • Kawasaki disease (in this case together with treatment with aspirin ), a disease in children where the blood vessels ( arterial s) in the body are enlarged.
  • Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), a rare and progressive disease that causes weakness in the arms and legs, numbness, pain, and fatigue.
  • Multifocal motor neuropathy (MMN), a rare disease that causes slowly progressing asymmetric weakness in the arms and legs without loss of sensation.

2. What you need to know before using Flebogamma DIF

Do not use Flebogamma DIF

  • if you are allergic to human normal immunoglobulin or any of the other ingredients of this medicine (listed in section 6)
  • if you do not have enough immunoglobulins of the type IgA in your blood or have developed IgA antibody is
  • If you suffer from fructose intolerance, a very rare inherited disease, the enzyme that breaks down fructose is not produced. Infants and young children (0-2 years) should not use this medicine as they may not yet be diagnosed with hereditary fructose intolerance ( hereditary fructose intolerance, HFI), which can be fatal. (see special warnings about excipients at the end of this section).

Warnings and cautions

Talk to your doctor, pharmacist, or nurse before using Flebogamma DIF.

Some side effects may occur more often:

  • at high infusion rate.
  • if this is the first time you are receiving Flebogamma DIF, or when switching from a product with human normal immunoglobulin (IVIg), or if it is a long time since your last infusion (eg several weeks), you will be closely monitored for up to one hour after infusion to detect signs of possible side effects.

Allergic reactions are rare. This can happen especially if you do not have enough IgA- type immunoglobulin in your blood or have developed antibodies to IgA.

Patients with previous risk factors

Tell your doctor if you have any other condition and/or disease, as control is required in patients with pre-existing risk factors for thrombotic events (blood clots form in your blood). Be especially careful to tell your doctor if you have:

  • diabetes
  • high blood pressure
  • previously affected by vascular disease or thrombosis
  • overweight
  • decreased blood volume
  • a disease that increases blood viscosity (blood sluggishness unit)
  • age over 65 years

Patients with kidney problems

If you have kidney disease and this is the first time you are getting Flebogamma DIF, you may have kidney problems.

Your doctor will consider your risk factors and take measures such as reducing the infusion or stopping treatment.

Effects on blood tests

After receiving Flebogamma DIF, the results of certain blood tests (serological tests) may be affected for some time. If you are taking a blood sample after receiving Flebogamma DIF, inform the person taking the sample or your doctor that you are taking this medicine.

Special safety warning

When drugs are made from human blood or plasma, several measures are taken to prevent the transmission of infection to patients. This includes:

  • careful selection of blood and plasma donors to ensure that those who can carry your infection have been excluded
  • testing of all donations and collections of plasma for signs of open viruses/infections
  • introduction of blood or plasma processing measures that can inactivate or remove viruses.

Despite these measures, the risk of transmission of infectious agents cannot be completely ruled out when medicinal products derived from human blood or plasma are administered. This also applies to new, hitherto unknown viruses or other types of infection.

The measures taken are considered to be effective for enveloped viruses such as human immunodeficiency virus ( HIV ), hepatitis B virus, or hepatitis C virus,s, and the non-enveloped hepatitis A virus or parvovirus B19.

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

It is strongly recommended that the product name and batch number (indicated on the label and carton after Lot) be registered each time Flebogamma DIF is administered to maintain a register of used batches.

Children and young people

Vital signs (body temperature, blood pressure, heart rate, and respiratory rate) should be followed during infusion one of Flebogamma DIF.

Other medicines and Flebogamma DIF

  • Tell your doctor or pharmacist if you are taking or have recently taken any other medicines.
  • Vaccine effects: Flebogamma DIF may reduce the effect of certain types of vaccines (live attenuated viral vaccines). In cases such as rubella, mumps, and chickenpox, a period of up to 3 months should run from the time you receive the medicine until you receive the vaccine. In the case of measles, this period is up to one year.
  • You should avoid using concomitant medicines that increase the excretion of water from the body (loop diuretics) during treatment with Flebogamma DIF.

Pregnancy and breastfeeding

If you are pregnant or breast-feeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Driving and using machines

Patients may experience reactions (such as dizziness and nausea) during treatment that may affect their ability to drive and use machines.

Flebogamma DIF contains sorbitol

This medicine contains 50 mg sorbitol per ml. If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicine.

In people older than 2 years who do not tolerate fructose, a spontaneous reaction to fructose-containing food develops which can cause the following symptoms: vomiting, disorders of the gastrointestinal tract, apathy, poor height growth, and weight loss. Therefore, patients should be carefully examined for symptoms of hereditary fructose intolerance before receiving Flebogamma DIF.

Flebogamma DIF contains sodium

This medicine contains less than 1 mmol (23 mg) sodium per vial of 10 ml, 50 ml, 100 ml, and 200 ml, ie essentially ‘sodium-free’. This product contains less than 29.41 mg sodium (the main ingredient in saline/table salt) per vial with 400 ml. This corresponds to 1.5% of the highest recommended daily intake of sodium for adults. Depending on the dose prescribed by your doctor, you may receive more than 1 vial.

3. How to use Flebogamma DIF

Flebogamma DIF is given as an injection into a vein ( intravenous administration ). It can be given by yourself if you have received full training from hospital staff. You need to prepare the infusion exactly as you were shown to prevent bacteria from entering. You must never give it to yourself when you are alone; a responsible adult must always be present.

The dose you receive varies depending on your illness and body weight and is calculated by your doctor (see section Instructions for healthcare professionals, given at the end of this leaflet).

At the beginning of infusion one, you will receive Flebogamma DIF at a slow rate (0.01-0.02 ml/kg/min). Depending on how you feel, your doctor may then slowly increase the infusion rate (up to 0.1 ml/kg/min).

Use for children over 2 years of age

Dose one in children is not considered different than in adults because dosage one is given according to the child’s disease and body weight.

If you take more Flebogamma DIF then you should

If you ingest more Flebogamma DIF than you should, your body may accumulate too much fluid. This can happen especially if you are a risk patient, e.g. an elderly patient or a patient who has heart or kidney problems. Tell your doctor immediately.

If you forget to take Flebogamma DIF

Tell your doctor or pharmacist immediately and follow his / her instructions.

You must not be given a double dose to make up for a forgotten dose.

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