1. What is UMAN BIG and what is it used for

UMAN BIG is a solution of human hepatitis B immunoglobulin. Immunoglobulins are blood proteins and are antibodies. UMAN BIG is used in the following therapies: prevention of hepatitis B virus recurrence after liver transplantation due to liver damage caused by hepatitis B virus, prevention of hepatitis B through immediate administration of antibodies that induce immunity in patients in the following cases: accidental exposure of non-immune individuals (i.e., individuals who have not been vaccinated against hepatitis B virus, including those whose vaccination has not been completed or whose status is unknown), in patients undergoing hemodialysis (i.e., patients with severe kidney failure requiring blood purification through so-called artificial kidneys) until the effectiveness of vaccination is achieved, in newborns born to mothers who are carriers of hepatitis B virus, and in individuals who do not respond to vaccination (i.e., individuals who do not have a immune response after vaccination) and those who require continuous prevention due to a constant risk of hepatitis B virus infection.

2. Important information before using UMAN BIG

When not to use UMAN BIG:

In individuals with immunoglobulin A (IgA) deficiency, antibodies against immunoglobulin A may develop in the blood. UMAN BIG contains a small amount of IgA, so these individuals may experience a severe allergic reaction. The doctor should weigh the benefits of using UMAN BIG against the potential risk of allergic reactions.

Warnings and precautions

Before starting treatment with UMAN BIG, discuss it with your doctor, pharmacist, or nurse. Ensure that UMAN BIG is not administered into the patient's blood vessel due to the risk of shock (acute circulatory failure). In carriers of hepatitis B surface antigen (HBsAg), administration of the medicine does not have an effect. Actual hypersensitivity reactions are rare. In rare cases, human hepatitis B immunoglobulin may cause a drop in blood pressure with an anaphylactic reaction (severe reaction with a drop in blood pressure, respiratory distress, fainting, sometimes fever, and skin reactions) even in patients who have previously tolerated human immunoglobulin treatment well. Suspected allergic or anaphylactic reaction requires immediate discontinuation of injection. In case of shock, follow the applicable medical standards for shock treatment. If any of the following symptoms occur: shortness of breath, pain, and swelling of the limb, loss of ability to move or feel a part of the body (focal neurological deficits), and chest pain, contact a doctor or the nearest hospital immediately, as these symptoms may indicate a progressing thrombotic event. The medicine contains 3.9 mg of sodium in 1 ml. Patients controlling sodium levels should take into account the amount of sodium in the diet depending on the required dose of the product. Medicines prepared from human blood or plasma are subject to certain procedures that are intended to prevent the transmission of infectious agents to treated patients. These procedures include: selection of blood and plasma donors, which aims to exclude donors who may be a source of infection, testing of plasma for the presence of infectious agents/viruses, and inclusion in the manufacturing process of methods that inactivate or remove viruses. Despite these precautionary measures, it cannot be completely excluded that the transmission of infectious agents through medicines prepared from human blood or plasma may occur. This also applies to unknown or newly discovered viruses and other types of infections. It is considered that the precautionary measures taken are effective against enveloped viruses, such as human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV), as well as non-enveloped viruses, such as hepatitis A virus (HAV). These measures may have limited effectiveness against non-enveloped viruses, such as parvovirus B19. It has not been found that immunoglobulins can cause hepatitis A or parvovirus B19 infection, as the presence of antibodies may play a protective role against viral infections. It is strongly recommended that each time UMAN BIG is used, the name and batch number should be recorded in order to facilitate the identification of the medicine. Effect on laboratory tests If the patient has received UMAN BIG, before taking a blood test, inform the doctor or nurse about it. UMAN BIG may affect the results of some serological tests for the presence of antibodies against red blood cells.

Children and adolescents

There are no special precautions or monitoring recommended for children and adolescents.

UMAN BIG and other medicines

Tell your doctor or pharmacist about all medicines you are taking or have recently taken, as well as any medicines you plan to take. Do not mix UMAN BIG with other medicines. Live attenuated viral vaccines In the period of 3 months after administration of UMAN BIG, it may affect the immune response obtained after vaccination with live attenuated viral vaccines, such as measles, mumps, rubella, and chickenpox. After administration of UMAN BIG, a minimum of 3 months should be allowed to pass before vaccination with a live attenuated viral vaccine. After vaccination with live attenuated viral vaccines, human hepatitis B immunoglobulin should be administered within 3 to 4 weeks; in case of need for administration of human hepatitis B immunoglobulin within 3 to 4 weeks after vaccination, the vaccination should be repeated 3 months after administration of human hepatitis B immunoglobulin.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a child, consult your doctor or pharmacist before using this medicine. Pregnancy The safety of using this medicine in pregnant women has not been established in controlled clinical trials, and therefore, it should be administered with caution to pregnant women. Clinical experience with immunoglobulins suggests that no harmful effects on the course of pregnancy, the fetus, or the newborn are expected. Breastfeeding The safety of using UMAN BIG in breastfeeding women has not been established in controlled clinical trials, and therefore, it should be administered with caution to breastfeeding women. Immunoglobulins pass into human milk and may participate in protecting the newborn's body against pathogens penetrating through the mucous membrane. Fertility Clinical experience with immunoglobulins suggests that no harmful effects on fertility are expected.

Driving and using machines

UMAN BIG has no or negligible influence on the ability to drive and use machines. Patients who have experienced side effects during treatment should wait for them to resolve before driving or operating machines.

UMAN BIG contains sodium

This medicine contains up to 3.9 mg of sodium in a 1 ml vial and 11.7 mg of sodium in a 3 ml vial (sodium is a major component of common salt). This corresponds to 0.19% and 0.58% of the maximum recommended daily intake of sodium in the diet for adults.

3. How to use UMAN BIG

This medicine should always be used exactly as your doctor or pharmacist has told you. If you are not sure, ask your doctor or pharmacist. UMAN BIG should be administered intramuscularly. Before use, the medicine should be brought to room temperature or body temperature. Remove the protective strip from the rubber stopper and draw the solution into a syringe for injection. Change the needle and administer. After emptying the vial and filling the syringe, the medicine should be administered immediately. The solution is clear and colorless or pale yellow or pale brown. Do not use solutions that are cloudy or have sediment. If it is necessary to use a larger volume (>2 ml in children or >5 ml in adults), it is recommended to administer it in different parts of the body in divided doses. Any unused product or waste material should be disposed of in accordance with local regulations.

Dosage

The appropriate dose for the patient will be determined by the doctor. The following dosages are usually used: Prevention of hepatitis B virus recurrence after liver transplantation due to liver damage caused by hepatitis B virus: Adults: Recommended dosage: 2160 IU intramuscularly every 15 days after transplantation, not counting the first week after surgery. In case of long-term treatment, this dosage should be adjusted to maintain the concentration of antibodies against HBs antigen in serum above 100 IU/l in HBV-DNA negative patients and above 500 IU/l in HBV-DNA positive patients. If necessary, consider concurrent use of appropriate antiviral drugs as standard prophylaxis against hepatitis B virus reinfection.

Use in children

There are no data on the use of UMAN BIG in children for the prevention of hepatitis B virus recurrence after liver transplantation due to liver damage caused by hepatitis B virus. Prevention of hepatitis B: Prevention of hepatitis B in case of accidental exposure in non-immune individuals: at least 500 IU, depending on the degree of exposure to infection, as soon as possible after exposure, preferably within 24-72 hours. Immunoprophylaxis of hepatitis B in patients undergoing hemodialysis: 8-12 IU/kg, up to a maximum of 500 IU, every 2 months until seroconversion (appearance of antibodies in serum) after vaccination. Prevention of hepatitis B in newborns whose mothers are carriers of hepatitis B virus, at birth or as soon as possible after birth: 30-100 IU/kg. Administration of human hepatitis B immunoglobulin may require repetition to achieve seroconversion after vaccination. In all these cases, vaccination against hepatitis B is highly recommended. The first dose of vaccination may be administered on the same day as human hepatitis B immunoglobulin, but in different parts of the body. In individuals who do not respond to vaccination (unmeasurable antibodies against hepatitis B virus) after vaccination and those who require continuous prophylaxis, administration of 500 IU every 2 months in adults and 8 IU/kg in children may be considered.

Overdose

There are no known consequences of overdose.
