GAMMAGARD S/D 5 g, POWDER AND SOLVENT FOR INFUSION SOLUTION

2. What you need to know before you use GAMMAGARD S/D

Do not use GAMMAGARD S/D

• If you are allergic (hypersensitive) to immunoglobulins or to any of the other components of this medicine (listed in section 6).
• If you have an immunoglobulin A deficiency. You may have anti-immunoglobulin A antibodies in your blood. GAMMAGARD S/D contains very small amounts of immunoglobulin A and you may develop an allergic reaction.

Warnings and precautions

Monitoring period required during infusion

• You will be closely monitored during the GAMMAGARD S/D infusion period to prevent you from suffering an allergic reaction. Your doctor will ensure that the infusion rate of GAMMAGARD S/D is suitable for you.

There may be a higher risk of side effects:

• if GAMMAGARD S/D is administered at a high rate,
• if you have a disorder characterized by low levels of antibodies in the blood (hypo- or agammaglobulinemia),
• if you have not received this medicine before or
• if a long period (e.g. several weeks) has passed since you last received it.

In these cases, you will be closely monitored during the infusion and for one hour after the infusion has ended, as there may be a higher risk of side effects.

If you have recently received GAMMAGARD S/D, you will only be observed during the infusion and for at least 20 minutes after the infusion.

When to stop or reduce the infusion rate

In rare cases, your body may be sensitized to medicines that contain antibodies. This can occur especially if you have an immunoglobulin A deficiency. In these rare cases, you may experience allergic reactions such as a sudden drop in blood pressure or shock, even if you have previously received treatment with medicines that contain antibodies.

• If you notice any of the following symptoms, inform your doctor or nurse immediately:
• Sudden wheezing, difficulty breathing or chest tightness
• Headache
• Fever
• Swelling of the eyelids, face, lips or blood vessels
• Hives or itchy skin
• Itching all over the body

Depending on your doctor's decision, the infusion rate may be reduced or stopped.

Special patient groups

Your doctor should exercise caution if you are overweight, elderly, diabetic, immobile, using estrogens, have a permanent vascular catheter or are prone to thrombosis.

Your doctor will closely monitor you if you have:

• high blood pressure
• low blood volume (hypovolemia)
• increased blood viscosity or vascular problems (vascular diseases including cardiac output or thrombotic episodes)
• excessive coagulation or coagulation disorders.

In these cases, immunoglobulins may increase the risk of myocardial infarction, stroke, pulmonary embolism or deep vein thrombosis, although this is very rare.

Inform your doctor if you are diabetic.

This medicine contains glucose. GAMMAGARD S/D does not contain sucrose or maltose.

Patients with diabetes mellitus should be aware that a 5% (50 mg/ml) solution of GAMMAGARD S/D contains 400 mg of glucose per gram of IgG. A 70 kg patient who receives a dose of 1 g/kg of IgG would receive 28 grams of glucose or 112 calories. This may affect their blood sugar level.

Your doctor will also take special care

The protein content may increase, causing increased blood viscosity

Information on the original material of GAMMAGARD S/D

GAMMAGARD S/D is manufactured from human plasma (the liquid part of the blood). When medicines are made from human blood or plasma, a number of measures are 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 carrying infections and testing of each donation and plasma pool for potential viruses or infections. The manufacturers of these products also include a series of steps in the processing of the 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 transmission of infections cannot be totally 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 (HBV) and hepatitis C virus (HCV), and for the non-enveloped hepatitis A virus (HAV). The measures taken may have limited value for non-enveloped viruses such as parvovirus B19.

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

It is recommended that each time you are given GAMMAGARD S/D, a record should be kept of the name of the medicine and batch number administered to maintain a record of the batches used.

Use of GAMMAGARD S/D with other medicines

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines or if you have been vaccinated in the last six weeks.

Infusion of immunoglobulins such as GAMMAGARD S/D may alter the effectiveness of some live virus vaccines such as measles, rubella, mumps and chickenpox. Therefore, after administration of these medicines, you may need to wait up to 3 months before receiving a live attenuated virus vaccine. You may need to wait up to 1 year after receiving immunoglobulins before receiving the measles vaccine.

Effects on blood tests

GAMMAGARD S/D contains a wide range of different antibodies, some of which may interfere with blood tests. If you have a blood test, please inform the analyst or your doctor that you have been given GAMMAGARD S/D.

Administration of Gammagard S/D may result in false positive readings in tests that rely on the detection of beta-D-glucans for the diagnosis of fungal infections; this may persist for several weeks after infusion of the product.

Pregnancy, breastfeeding and fertility

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 using this medicine.

• No clinical trials have been conducted with GAMMAGARD S/D in pregnant or breastfeeding women. Years of clinical experience with antibody-containing medicines have shown that no harmful effects are expected during pregnancy or for the baby.
• If you are breastfeeding, the antibodies in GAMMAGARD S/D may be present in breast milk. Therefore, your baby may be protected against certain infections.
• The effects of GAMMAGARD S/D on fertility have not been established.

Driving and using machines

Patients may experience reactions (e.g. dizziness or nausea) during treatment with GAMMAGARD S/D that could affect their ability to drive and use machines.

If this happens, wait until the reactions have disappeared.

Gammagard S/D 5 g contains sodium and glucose

This medicine contains 334 mg of sodium (main component of cooking/table salt) in each vial. This is equivalent to 17% of the maximum recommended daily intake of sodium for an adult.

This medicine contains glucose. Patients with diabetes mellitus should be aware that a 5% (50 mg/ml) solution of GAMMAGARD S/D contains 400 mg of glucose per gram of IgG. A 70 kg patient who receives a dose of 1 g/kg of IgG would receive 28 grams of glucose, which may affect their blood sugar level.

3. How to use GAMMAGARD S/D

GAMMAGARD S/D is for intravenous administration (injection into a vein). It will be administered by your doctor or nurse. The dose and frequency of infusion may vary depending on your situation and body weight.

At the start of the infusion, you will receive GAMMAGARD S/D at a low rate. Your doctor may gradually increase the infusion rate depending on whether you tolerate it well.

Use in children

In children (0 to 18 years), the same indications, dose and frequency of infusion are used as in adults.

If you use more GAMMAGARD S/D than you should

If you receive more GAMMAGARD S/D than you should, the blood may become thicker (hyperviscosity). The thicker the blood, the more difficult it is to transport through the blood vessels in your body, so less oxygen will be carried to vital organs, such as the brain, lungs, etc. This can occur especially if you are a high-risk patient (e.g. an elderly patient or a patient with kidney or heart problems). Make sure to drink enough fluids to avoid dehydration and inform your doctor if you have any health problems.

In case of overdose or accidental administration, consult the Toxicology Information Service. Telephone 915 620 420.

4. Possible side effects

Special precautions for storage

A chemical and physical stability of GAMMAGARD S/D reconstituted has been demonstrated for 24 hours at room temperature. From a microbiological point of view, the product should be used immediately, and the time and storage conditions before use are the responsibility of the user and should not normally exceed 24 hours at 2-8°C, when reconstitution has been carried out under controlled and validated aseptic conditions.

Reconstitution: Use an aseptic technique:

After reconstitution, only clear or slightly opalescent and colorless or yellowish solutions will be administered.

Bring the powder vial and the vial of water for injectable preparations (solvent) to room temperature. Maintain this temperature until the dissolution is complete.

• Solution at 5%
  1. Remove the protectors from the vials and clean the stoppers with a germicidal solution.
  2. Remove the protector covering the spike of the transfer device. Do not touch the spike.

3a. Place the solvent vial on a smooth surface.

Use the exposed end of the spike to pierce the solvent vial through the center of the stopper.

PRECAUTION: if the spike is not inserted into the center of the stopper, it may become loose and the vacuum may be lost.

3b. Ensure that the vial neck is fully engaged in the device by pressing the transfer device firmly.

Remove the protector covering the other end of the spike while holding the transfer device. Do not touch the spike.

1. Maintain the solvent vial with the transfer device connected at an angle with respect to the powder vial to prevent the solvent from spilling.

Note: do not place the solvent vial downwards, as the solvent may spill.

5a. Pierce the powder vial through the center of the stopper while quickly inverting the solvent vial to avoid spilling the solvent.

PRECAUTION: if the spike is not inserted into the center of the stopper, it may become loose and the vacuum may be lost.

5b. Ensure that the vial neck is fully engaged in the device by pressing the solvent vial firmly.

1. After all the solvent has passed into the powder vial, remove the transfer device and the empty solvent vial. Immediately rotate the concentrate vial to mix the contents thoroughly.

PRECAUTION: do not shake. Avoid foam formation.

After a single use, discard the transfer device.

• Solution at 10%
  1. Remove the protectors from the vials and clean the stoppers with a germicidal solution.
  2. To prepare a 10% solution, it is necessary to extract half of the solvent volume. Table 2 describes the solvent volume to be extracted from each vial to achieve a 10% solution before connecting the transfer device. Using an aseptic technique, remove the unnecessary solvent volume using a sterile hypodermic syringe and needle. Discard the syringe and needle containing the unused solvent.
  3. Using the residual solvent in the solvent vial, follow steps 2-6 described in section A.

Administration. Use an aseptic technique

Follow the instructions for use of the administration kit included in the packaging. If another administration kit is used, ensure it contains a similar filter.

Instructions for use and handling

The product should be brought to room temperature or body temperature before use.

Complete dissolution should be achieved within 30 minutes.

The resulting solution should be clear or slightly opalescent and colorless or yellowish. Do not use solutions that are turbid or contain sediment. The reconstituted product should be visually inspected before administration to verify the absence of particles and coloration.

Disposal of unused medication and all materials that have come into contact with it should be carried out in accordance with local regulations.

Discard the transfer device after a single use.

Form of administration

Intravenous route.

If possible, it is recommended that the 10% solution of GAMMAGARD S/D be administered through the antecubital veins. This may reduce the likelihood of discomfort at the infusion site.

GAMMAGARD S/D at 5% (50 mg/ml) should be administered intravenously at an initial rate of 0.5 ml/kg/h. In general, it is recommended that patients who receive GAMMAGARD S/D for the first time or switch from another intravenous immunoglobulin to GAMMAGARD S/D start treatment with the lowest administration rate and then increase to the maximum rate if they have previously tolerated several infusions at intermediate infusion rates.

If well tolerated, the administration rate of the 5% solution can be gradually increased up to a maximum of 4 ml/kg/h. When switching from a 5% solution to a 10% solution, the administration rate of the 10% solution should be initially low to maintain a comparable administration rate of IgG protein. In many patients, it is possible to gradually increase the administration rate of the 10% solution up to 8 ml/kg/h. The administration rate will be adjusted individually according to patient tolerability.

Special precautions

Any infusion-related adverse effect should be treated by reducing the rate or stopping the infusion.

Each time GAMMAGARD S/D is administered, it is recommended to indicate the product name and batch number.

Incompatibilities

GAMMAGARD S/D should not be mixed with other medications. It is recommended to administer GAMMAGARD S/D separately from other medications the patient is receiving.
