1. What is Igantet 250 and what is it used for

Igantet 250 is a solution for injection in a 1 ml syringe-ampoule.
It is obtained from plasma from donors containing specific antibodies against tetanus toxin.
Indications for use
Igantet 250 is used:

• to prevent tetanus in people with fresh wounds that may be infected with tetanus spores; in people who have not been vaccinated in the last 10 years, or have been vaccinated inconsistently or have an unknown vaccination history,
• to treat tetanus.

2.

Important information before using Igantet 250

When not to use Igantet 250

• if hypersensitivity to any component of the medicine occurs,
• in case of hypersensitivity to human immunoglobulin. Particular caution should be exercised when using Igantet 250
• in case of IgA deficiency and the presence of anti-IgA antibodies,
• Ensure that the needle is not in a blood vessel, by withdrawing the syringe plunger, as intravascular administration may cause anaphylactic shock.
• Allergic reactions after administration of human tetanus immunoglobulin are possible, although they occur rarely. In case of anaphylactic shock, proceed according to the principles of anaphylactic shock treatment.
• After administration of Igantet 250, the patient should remain under medical observation for at least 20 minutes.

Warnings and precautions

In the process of producing medicines from human blood or plasma, certain procedures are used to prevent the transmission of infection to treated patients. These procedures include the selection of blood and plasma donors, the purpose of which is to exclude donors who may be a source of infection;
testing of plasma for the presence of infectious agents. Manufacturers of these medicines use processes that inactivate or eliminate viruses. Despite the use of preventive measures, it is not possible to completely exclude the possibility of transmitting infection if medicines produced from human blood or plasma are administered. This also applies to unknown or newly discovered viruses and other pathogens.
The risk of transmitting infectious agents is significantly reduced by using appropriate procedures:

• donor selection based on medical history and screening tests of individual donations and plasma pools for the presence of HBsAg and anti-HIV and HCV antibodies,
• testing of plasma pools for the presence of HCV genetic material,
• use of virus inactivation and removal processes during production, validated using model viruses. These processes are considered effective against HIV, HCV, HAV, and HBV viruses.

The above actions may have limited value in the case of pathogens such as parvovirus B19. So far, the evidence suggests that immunoglobulin preparations do not transmit hepatitis A virus or parvovirus B19. It is assumed that the presence of antibodies plays a significant role in protecting against viral infections.
For the benefit of patients, it is recommended that whenever possible, the name and batch number of Igantet 250 should be recorded.

Igantet 250 and other medicines

Inform your doctor about all medicines you have taken recently, including those available without a prescription. Inform your doctor about recent vaccinations.
Vaccines containing live attenuated viruses
Using immunoglobulins may weaken the effectiveness of vaccines containing live attenuated viruses for at least 6 weeks to 3 months
after administration.
Effect on serological test results
After administration of immunoglobulins, there is a transient increase in passively introduced antibodies in the patient's blood, which may cause false-positive serological test results.

Pregnancy and breastfeeding

The safety of using the medicine during pregnancy has not been the subject of controlled clinical trials, therefore it should be used with caution in pregnant or breastfeeding women. Long-term clinical experience with immunoglobulins, in particular anti-D immunoglobulin, does not indicate that one should expect a negative effect on the course of pregnancy, fetal development, or the newborn.
Immunoglobulins are excreted in human milk, which may contribute to the transfer of protective antibodies to the newborn.

Driving and using machines

No effect of human tetanus immunoglobulin on the ability to drive and use machines has been observed.

3. How to use Igantet 250

Before administration, warm the medicine to room temperature or body temperature.

• Administer slowly intramuscularly.
• If larger doses are required (5 ml or more), it is recommended to divide the dose and administer it in different locations.
• If tetanus immunoglobulin and vaccine are administered simultaneously, use separate syringes and needles. Perform injections in different parts of the body.

After cleaning the wound, removing foreign bodies, and dead tissue, assess the indication for active immunization with tetanus vaccine and simultaneous administration of human tetanus immunoglobulin intramuscularly in a different part of the body, according to the following guidelines:

• Clean and minor injuries

It is not recommended to vaccinate or use tetanus immunoglobulin in patients who have received a booster dose of tetanus vaccine in the last 10 years or have been vaccinated according to the tetanus vaccination program.
Vaccination is recommended for patients who have not received a booster dose in the last 10 years or have not been vaccinated according to the tetanus vaccination program, as well as for those with an unknown vaccination history. Administration of tetanus immunoglobulin is not necessary.

• Contaminated major injuries

It is not recommended to vaccinate patients who have received a booster dose of tetanus vaccine in the last 5 years or have been vaccinated according to the tetanus vaccination program.
Vaccination should be performed if more than 5 years have passed since the last booster dose.
In both cases, administration of tetanus immunoglobulin is not necessary.
In the case of patients who have not been vaccinated according to the tetanus vaccination program or have an unknown vaccination history, vaccination should be performed simultaneously with tetanus immunoglobulin.
For active immunization, a vaccine containing only tetanus toxoid (T) or tetanus and diphtheria toxoids (Td vaccine for adults) can be used. The Td vaccine should not be used in patients with impaired immunity.
The doctor should assess the risk of tetanus based on the likelihood of wound infection with Clostridium tetani.
Doses for children and adults are the same.

• Tetanus prevention

250 IU intramuscularly.
The dose should be doubled (500 IU) in case of complicated wounds (deep wounds with damaged tissues, contaminated), or if more than 24 hours have passed since the injury, or in case of overweight adults.

• Tetanus treatment

The results of several studies suggest the importance of using single doses of 3000 to 6000 IU of human tetanus immunoglobulin in the treatment of tetanus, simultaneously with other appropriate treatment methods.

Using a higher dose of Igantet 250 than recommended

The consequences of overdose are unknown.

4. Possible side effects

Like all medicines, Igantet 250 can cause side effects, although not everybody gets them.
Pain and tenderness may occur at the injection site. This can be prevented by dividing the dose and administering it in different locations.
Sometimes, fever, chills, and skin reactions may occur. Rarely, the following have been observed: nausea, vomiting, decreased blood pressure, tachycardia, and allergic and anaphylactic reactions, including anaphylactic shock.
There is no precise information on the frequency of side effects from clinical trials and post-marketing experience.
Information on the risk of virus transmission - see Warnings and precautions.
