human tetanus immunoglobulin at a glance
Medicine class
Tetanus-specific human immunoglobulin providing passive immunity
Usual role
Immediate protection after selected tetanus-prone injuries
Administration
Given by a healthcare professional, usually by injection into a muscle
Vaccination
Does not replace tetanus vaccination; when both are needed, they are injected at different sites
What is human tetanus immunoglobulin used for?
The selected product is licensed to prevent tetanus after a tetanus-prone injury.
For people who have not been adequately vaccinated or whose vaccination history is uncertain.
For people with severe antibody-production deficiency.
For vaccinated people whose wound presents a high tetanus risk.
How does human tetanus immunoglobulin work?
It supplies ready-made IgG antibodies that bind the toxin produced by Clostridium tetani. This provides temporary passive protection but not the lasting immune memory produced by vaccination.
How to take human tetanus immunoglobulin
A trained healthcare professional normally injects it into a muscle. It must not be injected into a blood vessel or mixed with other injectable medicines. If tetanus vaccine is also required, it is given at a different injection site.
Tell the clinician about bleeding disorders, previous reactions to immunoglobulins or blood products, IgA deficiency, clotting risks, and recent or planned vaccinations.
The solution should not be used if it is cloudy or contains deposits.
The product name and batch number should be recorded.

- A sudden fall in blood pressure
human tetanus immunoglobulin in pregnancy
Controlled pregnancy studies are unavailable, but clinical experience with human immunoglobulins does not suggest harm to pregnancy or the baby. A clinician should assess the need for protection after the injury.
human tetanus immunoglobulin while breastfeeding
Human immunoglobulins pass into breast milk and are not expected to harm a breastfed baby. Tell the treating clinician that you are breastfeeding.
human tetanus immunoglobulin interactions
The main clinically relevant interaction is with certain vaccines.
Live attenuated viral vaccines, including measles, mumps, rubella and varicella vaccines
Transferred antibodies may reduce the immune response, so the vaccination team should plan timing.
Tetanus-containing vaccine
It may be given at the same attendance when indicated, but at a different injection site.
Common questions about human tetanus immunoglobulin
Answers are fully visible for fast scanning and source review.
Is human tetanus immunoglobulin the same as a tetanus vaccine?
No. It supplies ready-made antibodies for temporary protection, while vaccination stimulates longer-term immune memory. It does not replace vaccination.
Can it be given with tetanus vaccine?
Yes, when both are indicated, but they must be injected at different anatomical sites.
