1. What is Niuliva and what is it used for
Niuliva is presented as a solution for intravenous infusion containing 250 U.I./ml of human hepatitis B immunoglobulin.
This medicinal product belongs to the pharmacotherapeutic group called immune sera and immunoglobulins.
Niuliva is used for:
Prevention of hepatitis B virus (HBV) reinfection after liver transplantation due to liver failure caused by hepatitis B in patients without active viral replication before transplantation.
Hepatitis B immunoprophylaxis
- In case of accidental exposure in non-immunized subjects (including individuals with incomplete or unknown vaccination).
- In patients undergoing hemodialysis, until vaccination becomes effective.
- In newborns of mothers carrying the hepatitis B virus.
- In subjects who did not develop an immune response (unmeasurable anti-hepatitis B antibodies) after vaccination and require continuous prevention due to ongoing risk of hepatitis B infection.
If you have any doubts about the use of Niuliva, consult your doctor.
2. Before using Niuliva
Do not use Niuliva
- if you are allergic (hypersensitive) to human immunoglobulins or to any of the other components of Niuliva.
- if you have intolerance to fructose, a rare genetic disease characterized by the inability to break down fructose.
(See special warnings about excipients at the end of this section).
Take special care with Niuliva
Some adverse reactions may occur more frequently
? in the case of high infusion rate.
? if you have hypo- or agammaglobulinemia (a condition characterized by low levels of immunoglobulin in your blood) with or without IgA deficiency.
Pulmonary adverse reactions (acute transfusion-related lung injury, TRALI) may occur if you receive intravenous immunoglobulin.
True hypersensitivity reactions are rare. The symptoms of hypersensitivity reactions are: skin rash, generalized urticaria, chest tightness, difficulty breathing, decreased blood pressure (hypotension), and severe allergic reaction (anaphylaxis).
Niuliva contains a small amount of IgA. If you have IgA deficiency, you are at risk of developing anti-IgA antibodies and suffering allergic reactions after administration of blood-derived products (hemoderivatives) containing IgA. Your doctor should weigh the benefits of treatment with Niuliva against the potential risks of hypersensitivity reactions.
Rarely, human hepatitis B immunoglobulin may induce a drop in blood pressure with an allergic reaction, even if you have previously tolerated treatment with immunoglobulin.
Patients with pre-existing risk factors
Please inform your doctor if you have any other medical condition or disease, as this may require greater caution. In particular, inform your doctor if you have thrombotic risk factors (risk of developing blood clots or thrombi in your circulation).
Consult your doctor, even if any of the above circumstances have occurred to you in the past.
Special safety precautions
When administering medicines derived from human plasma or blood, certain measures must be taken to prevent infections from being transmitted to patients. These measures include careful selection of donors to exclude those at risk of carrying infectious diseases, analysis of specific infection markers in individual donations and plasma pools, as well as inclusion of stages in the manufacturing process to eliminate/inactivate viruses. Despite this, when administering medicines derived from human blood or plasma, the possibility of transmitting infectious agents cannot be entirely excluded. This also applies to emerging or unknown 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, and for the non-enveloped hepatitis A virus. 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 contained in the product are protective.
It is highly recommended that each time you receive a dose of Niuliva, the name of the medicine and batch number administered be recorded to maintain a record of the batches used.
Use of other medicines
? Inform your doctor or pharmacist if you are using or have recently used other medicines, including those obtained without a prescription.
? Effects on vaccines: Niuliva may reduce the effectiveness of certain types of vaccines such as measles, rubella, mumps, and varicella.
Effects on blood tests
If a blood test is performed after receiving Niuliva, please inform the analyst or your doctor that you have received this medicine. The level of some antibodies may increase.
Pregnancy and breastfeeding
Consult your doctor or pharmacist before using any medicine.
Inform your doctor if you are pregnant or breastfeeding. Your doctor will decide whether Niuliva can be used during pregnancy and breastfeeding.
Driving and using machines
No effects on the ability to drive vehicles or use machinery have been observed.
Important information about some of the components of Niuliva
This medicine contains 50mg of sorbitol per ml.If your doctor has informed you that you suffer from intolerance to some sugars, contact them before using this medicine.
In newborns and children up tothe weaning period, hereditary fructose intolerancemay not have been diagnosed yet, and administration of Niuliva may trigger severe effects. When treatment with Niuliva is considered appropriate for newborns and children (especiallyup to the weaning period), it should be exercised with great caution before and during administration of Niuliva due to the amount of sorbitol contained in the product. This is especially important when more than one dose is needed to achieve protective antibody titers.
No interference with blood glucose level determination is expected.
3. How to use Niuliva
Follow these instructions unless your doctor has given you different instructions.
Prevention of hepatitis B virus (HBV) reinfection after liver transplantation due to liver failure caused by hepatitis B in patients without active viral replication before transplantation:
In adults:
10,000 U.I. on the day of transplantation, during surgery. Afterward, 2,000 - 10,000 U.I./day for 7 days, and as needed to maintain antibody levels above 100 - 150 U.I./l in HBV DNA-negative patients.
In children:
The dosage should be adjusted based on body surface area, at 10,000 U.I./1.73 m2.
Hepatitis B immunoprophylaxis:
- Prevention of hepatitis B in case of accidental exposure in non-immunized subjects:
At least 500 U.I., depending on the intensity of exposure, as soon as possible after exposure, and preferably between 24 - 72 hours.
- Hepatitis B immunoprophylaxis in patients undergoing hemodialysis:
8 - 12 U.I./kg with a maximum of 500 U.I., every 2 months until seroconversion after vaccination.
- Prevention of hepatitis B in newborns of mothers carrying the hepatitis B virus, at birth or as soon as possible after birth:
30 - 100 U.I./kg. Administration of hepatitis B immunoglobulin should be repeated until seroconversion after vaccination.
In all these situations, vaccination against hepatitis B virus is strongly recommended. The first dose of the vaccine can be administered on the same day as the human hepatitis B immunoglobulin, although at different sites.
In subjects who did not develop an immune response (unmeasurable anti-hepatitis B antibodies) after vaccination and require continuous prevention, administration of 500 U.I. in adults and 8 U.I./kg in children every 2 months may be considered; the minimum protective antibody titer is considered 10 mU.I./ml.
Niuliva should be administered intravenously at an initial infusion rate of up to 0.02 ml/kg/min for the first 10 minutes. If you tolerate this infusion rate well, your doctor may gradually increase the infusion rate up to a maximum of 0.04 ml/kg/min. Therefore, generally, administration of 5,000 U.I. will take less than 15 minutes.
If no adverse reactions occur, the initial infusion rate for subsequent infusions will also be up to 0.02 ml/kg/min, and if you tolerate this infusion rate well, your doctor may gradually increase the infusion rate up to a maximum of 0.1 ml/kg/min. In general, the administration time for 5,000 U.I. will be less than 10 minutes.
Niuliva should not be mixed with other medicines or intravenous solutions and should be administered using equipment exclusively for its administration.
If you use more Niuliva than you should
If you have been given more Niuliva than you should, consult your doctor or pharmacist immediately.
The consequences of an overdose are not known.
If you forget to use Niuliva
Consult your doctor or pharmacist immediately and follow their instructions.
You should not be given a double dose to make up for forgotten doses.
