FLEBOGAMMA DIF 50 mg/ml SOLUTION FOR INFUSION

2. What you need to know before you use Flebogamma DIF

Do not use Flebogamma DIF

• If you are allergic to human immunoglobulins or to any other component of this medicine (included in section 6).

• If you have IgA deficiency in blood or have developed antibodies to IgA.

• If you have fructose intolerance, a rare genetic disease that consists of the inability to produce the enzyme responsible for breaking down fructose. In infants and young children (0-2 years), hereditary fructose intolerance (HFI) may not have been diagnosed and could be fatal, so they should not receive this medicine. (See special precautions regarding excipients at the end of this section).

Warnings and precautions

Consult your doctor, pharmacist, or nurse before starting to use Flebogamma DIF.

Some adverse reactions may occur more frequently:

• if administered at a high infusion rate.
• if you receive Flebogamma DIF for the first time, or have changed from another human normal immunoglobulin (IgIV) product, or a long period of time (e.g., several weeks) has elapsed since the last infusion. You will be closely monitored for up to one hour after the infusion to detect possible adverse reactions.

Allergic reactions are rare. These may occur in isolated cases if you do not have sufficient IgA immunoglobulins in your blood or if you have developed anti-IgA antibodies.

Patients with pre-existing risk factors

Please inform your doctor if you have any other medical condition and/or disease, as closer monitoring is required in patients with pre-existing risk factors for thrombotic events (blood clot formation). In particular, inform your doctor if you have:

• diabetes
• high blood pressure
• history of vascular disease or thrombotic events
• overweight
• reduced blood volume
• diseases that increase blood viscosity
• aged over 65 years

Patients with kidney problems

If you have kidney disease and receive Flebogamma DIF for the first time, you may experience kidney problems.

Your doctor will consider the existing risk factors in your case and take appropriate measures, such as reducing the infusion rate or stopping treatment.

Effects on blood tests

After receiving Flebogamma DIF, the results of certain blood tests (serological tests) may be altered for some time. If you have a blood test after receiving Flebogamma DIF, please inform the analyst or your doctor that you have received this medicine.

Special safety precautions

When medicines are prepared from human blood or plasma, a series of measures must be taken to prevent the possible transmission of infections to patients. These measures include:

• careful selection of blood and plasma donors to ensure the exclusion of donors at risk of having infections,

• analysis of each donation and plasma pool to detect possible viruses or infections,

• inclusion of a series of stages in the processing of blood or plasma that can inactivate or eliminate viruses.

Despite these measures, when medicines prepared from human blood or plasma are administered, the possibility of transmitting infections cannot be completely excluded. This also applies to 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 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, such as those contained in the medicine, are protective.

It is highly recommended that each time Flebogamma DIF is administered to a patient, a record is kept of the name of the medicine and the batch number administered (indicated on the label and box after Batch) to maintain a relationship between the patient and the product batch.

Children and adolescents

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

Using Flebogamma DIF with other medicines

• Tell your doctor or pharmacist if you are taking or have recently taken any other medicines.

• Effects on vaccines: Flebogamma DIF may reduce the effectiveness of certain types of vaccines (live attenuated vaccines). In the case of rubella, mumps, and varicella, a period of up to 3 months should elapse after receiving this medicine and before receiving these vaccines. In the case of measles, the period is up to 1 year.

• Concomitant use with medicines that increase water excretion from the body (loop diuretics) should be avoided during treatment with Flebogamma DIF.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, 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 or nausea) during treatment that could affect their ability to drive and use machines.

Flebogamma DIF contains sorbitol

Sorbitol is a source of fructose. If you (or your child) have hereditary fructose intolerance (HFI), a rare genetic disease, you must not receive this medicine. Patients with HFI cannot break down fructose, which can cause serious adverse effects.

Consult your doctor before receiving this medicine if you (or your child) have HFI or if your child cannot take sweet foods or drinks because they cause dizziness, vomiting, or unpleasant effects such as bloating, stomach cramps, or diarrhea.

Flebogamma DIF contains sodium

This medicine contains less than 7.35 mg of sodium (main component of cooking/table salt) per 100 ml. This is equivalent to 0.37% of the maximum daily intake of 2 g of sodium recommended for an adult.

3. How to use Flebogamma DIF

Flebogamma DIF is for intravenous administration (injection into a vein). You can administer it yourself if you have previously received complete training from hospital staff or a healthcare professional. You must perform the infusion exactly as you have been taught to avoid the presence of germs. You should never administer an injection if you are alone; a healthcare professional with experience in preparing medicines, cannulation, administration, and monitoring of adverse reactions should always be present.

The dose you receive will depend on your disease and weight and will be calculated by your doctor (see section "Instructions for healthcare professionals" at the end of the leaflet).

At the start of the infusion, you will receive Flebogamma DIF at a low rate (0.01-0.02 ml/kg/min). If you tolerate it well, your doctor may gradually increase the infusion rate (up to 0.1 ml/kg/min).

Use in children over 2 years

The dose in children is not considered to be different from that in adults, as it depends on the disease and the child's weight.

If you receive more Flebogamma DIF than you should

If you receive more Flebogamma DIF than you should, your body may experience fluid overload. This can occur especially if you are a high-risk patient, for example, if you are elderly or have heart or kidney problems. Consult your doctor immediately.

If you forget to use Flebogamma DIF

Consult your doctor or pharmacist immediately and follow their instructions.

You should not administer a double dose to make up for a forgotten dose.

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

Posology and Method of Administration

The dose and dosing regimen depend on the indication.

It may be necessary to individualize the dosing regimen for each patient according to the clinical response. The dose based on body weight may require adjustment in patients with low weight or overweight. The following dosing regimen can be used as a guideline.

The recommended posology is described in the following table:

Flebogamma DIF should be administered intravenously at an initial rate of 0.01-0.02 ml/kg/min during the first thirty minutes. If well tolerated, the administration rate can be gradually increased up to a maximum of 0.1 ml/kg/min.

In the clinical trial conducted with patients with chronic ITP, a significant increase in mean platelet levels (64,000/µl) was obtained, although without reaching normal levels.

Pediatric Population

Since the posology for each indication is based on body weight and adjusted according to the clinical outcome of the conditions indicated above, the posology in children does not differ from that indicated for adults.

Incompatibilities

Flebogamma DIF should not be mixed with other medicines or intravenous solutions and should be administered using a separate intravenous line.

Special Precautions

Sorbitol

Patients with hereditary fructose intolerance (HFI) should not receive this medicine unless it is strictly necessary.

Infants and children (under 2 years) may not be diagnosed with hereditary fructose intolerance (HFI). Medicines (containing sorbitol/fructose) administered intravenously can be potentially fatal and should be contraindicated for this population unless there is an absolute clinical need and no alternative is available.

Before receiving this medicine, the patient's medical history should be thoroughly reviewed for symptoms of HFI.

It is highly recommended that each time Flebogamma DIF is administered to a patient, a record is kept of the name of the medicine and the batch number administered in order to maintain a relationship between the patient and the batch of the product.

Handling and Disposal Instructions

The product should reach room temperature (not above 30 °C) before use.

The solution should be transparent or slightly opalescent. Do not use Flebogamma DIF if the solution is turbid or contains sediment.
