1. What Gamma Anti-Tetanus Grifols is and what it is used for
It is presented as a solution for injection in a pre-filled syringe. Each pack of Gamma Anti-Tetanus Grifols contains a pre-filled syringe with human anti-tetanus immunoglobulin which are antibodies against tetanus toxin.
This medicine belongs to the pharmacotherapeutic group called immune sera and immunoglobulins.
Administration of Gamma Anti-Tetanus Grifols is indicated in:
- Post-exposure prophylaxis:
Immediate prevention after wounds that may be contaminated with tetanus if you have not been adequately vaccinated, if your immunization status is not known with certainty, and if you have a severe deficiency in antibody production.
- Treatment of clinically manifested tetanus.
Active tetanus vaccination should always be administered together with anti-tetanus immunoglobulin unless there are contraindications or confirmation of adequate vaccination.
2. Before you use Gamma Anti-Tetanus Grifols
Do not use Gamma Anti-Tetanus Grifols
- if you are allergic (hypersensitive) to human immunoglobulins or to any of the other components of Gamma Anti-Tetanus Grifols.
Take special care with Gamma Anti-Tetanus Grifols
- Make sure that Gamma Anti-Tetanus Grifols is not administered into a blood vessel, due to the possibility of shock.
- Allergic reactions may occur, although rarely.
- Gamma Anti-Tetanus Grifols contains a small amount of IgA. If you have an IgA deficiency, you may develop anti-IgA antibodies and suffer allergic reactions after administration of blood-derived products (hemoderivatives) that contain IgA. Your doctor should weigh the benefit of treatment with Gamma Anti-Tetanus Grifols against the potential risks of hypersensitivity reactions.
- Rarely, human anti-tetanus immunoglobulin may induce a drop in blood pressure with an allergic reaction, even if you have previously tolerated treatment with human immunoglobulin.
- You should be under observation for at least 20 minutes after administration of the product.
Special precautions for safety
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 being carriers of 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 healthcare personnel administer a dose of Gamma Anti-Tetanus Grifols, they record the name of the medicine and batch number administered in order to maintain a record of the batches used.
Use of other medicines
- Tell your doctor or pharmacist if you are using, or have recently used, other medicines, including those obtained without a prescription.
- Effects on vaccines: Gamma Anti-Tetanus Grifols may reduce the effectiveness of certain types of vaccines such as measles, rubella, mumps, and varicella. You may need to wait 3 months before receiving these vaccines. In the case of measles, you may need to wait 5 months before receiving the vaccine.
Effects on blood tests
Tell the analyst or your doctor that you have received this medicine if a blood test is performed after receiving Gamma Anti-Tetanus Grifols. The level of some antibodies may increase.
Pregnancy and breastfeeding
Consult your doctor or pharmacist before using any medicine.
Tell your doctor if you are pregnant or breastfeeding. Your doctor will decide if Gamma Anti-Tetanus Grifols can be used during pregnancy and breastfeeding.
Driving and using machines
The influence of Gamma Anti-Tetanus Grifols on the ability to drive and use machines is nil.
Important information about some of the components of Gamma Anti-Tetanus Grifols

3. How to use Gamma Anti-Tetanus Grifols
Follow these instructions unless your doctor has given you different instructions.
The wound should be cleaned before you are administered the intramuscular injection of Gamma Anti-Tetanus Grifols. In some cases, active immunization with tetanus vaccine should be started simultaneously, administering it in a different area of the body than the immunoglobulin, according to the following instructions:
- Minor and clean wounds
If you have completed your tetanus vaccination cycle or have received the last booster dose in the last 10 years, revaccination and use of Gamma Anti-Tetanus Grifols are not recommended.
If you have not completed your tetanus vaccination cycle, or your immunization status is unknown, or more than 10 years have passed since your last booster, a vaccine dose is recommended. It is not necessary to administer Gamma Anti-Tetanus Grifols.
- Major or dirty wounds
If you have completed your tetanus vaccination cycle and have also received your last booster dose in the last 5 years, revaccination is not necessary; but if more than 5 years have passed since your last booster, a vaccine dose is necessary. In both cases, it is not necessary to administer Gamma Anti-Tetanus Grifols.
If you have not completed your tetanus vaccination cycle, or your immunization status is unknown, in addition to the vaccine dose, Gamma Anti-Tetanus Grifols will be administered.
The doctor will determine if a minor wound is susceptible to being contaminated.
Children and adults should receive the same dose.
- Prevention in case of wounds susceptible to being contaminated with tetanus:
- 250 UI unless the risk is considered extremely high.
- The dose may be increased to 500 UI in:
- infected wounds, when adequate surgical treatment cannot be performed within the next 24 hours.
- penetrating or contaminated wounds with tissue destruction and lack of oxygen, as well as wounds caused by foreign bodies (e.g., bites, stings, or gunshot wounds).
- Treatment of clinically manifested tetanus:
Single doses of 3000 to 6000 UI by intramuscular route in combination with other appropriate clinical therapies.
Gamma Anti-Tetanus Grifols should be administered by intramuscular route.
If you need a large volume (> 2 ml in children or > 5 ml in adults), it is recommended to administer it in fractionated doses and in different regions of the body.
When simultaneous vaccination is necessary, the immunoglobulin and vaccine should be administered in two different regions of the body.
For prevention in case of wounds susceptible to being contaminated with tetanus, if intramuscular administration is contraindicated (coagulation disorders), the injection can be administered subcutaneously. However, it should be noted that there are no clinical efficacy data to support subcutaneous administration.
For the acute treatment of clinically manifested tetanus, if intramuscular administration is not clinically appropriate, an alternative intravenous product can be used if available.
Gamma Anti-Tetanus Grifols should not be mixed with other medicines.
If you use more Gamma Anti-Tetanus Grifols than you should
If you have been administered more Gamma Anti-Tetanus Grifols than you should, consult your doctor or pharmacist immediately.
The consequences of an overdose are not known.
In case of overdose or accidental administration, consult the Toxicology Information Service. Telephone 91 562 04 20.
If you forget to use Gamma Anti-Tetanus Grifols
Consult your doctor or pharmacist immediately and follow their instructions.
