# Medicines to Prevent Tetanus | |
Some wounds can cause tetanus unless the person has already had the | |
necessary vaccinations. Antitetanus immunoglobulin and the tetanus | |
vaccine are 2 medicines given by injection that prevent tetanus after | |
a wound. One or both are needed depending on whether the person is | |
up-to-date with tetanus vaccinations and the seriousness of the | |
wound. Give the necessary injections as soon as possible. Do not | |
wait for signs of tetanus. | |
A person is up-to-date with tetanus vaccines, when: | |
* They had all 6 doses (a series of 3 as a baby, and later at least | |
3 boosters). | |
OR | |
* They had the first 3 doses and at least one booster within the | |
last 10 years. | |
To know which medicines to prevent tetanus are needed, it is best to | |
know if the person has had a vaccine against tetanus and when. Many | |
people do not know if they have had these vaccines. If their | |
vaccination history is unknown, give medicines as if they are not | |
up-to-date with their vaccines. | |
-> Give the vaccine against tetanus AND give antitetanus | |
immunoglobulin globulin: | |
* If the wound is deep or dirty and the person has not had a | |
tetanus vaccine within the last 5 years or their vaccination | |
history is unknown. | |
-> Give the vaccine against tetanus but do not give antitetanus | |
immunoglobulin globulin: | |
* For any wound, even one that is minor and clean, if it is not | |
certain that the person received at least 3 vaccinations against | |
tetanus (the first 3 doses are usually given during a baby's first | |
year). | |
* If the wound is deep or dirty and 5 years or more has passed | |
since the most recent tetanus vaccine or vaccine booster. | |
* If the wound is minor and clean and 10 years or more has passed | |
since the most recent tetanus vaccine or vaccine booster. | |
-> No injection is needed: | |
* If the wound is deep or dirty but the most recent tetanus vaccine | |
was within the last 5 years. | |
* If the wound is minor and clean and the person is up-to-date with | |
their tetanus vaccines. | |
But if the person has HIV or another illness that lowers their | |
immunity, give antitetanus immunoglobulin for any wound, even a minor | |
one. If they are not up-to-date with the tetanus vaccine, they will | |
need the tetanus vaccine too. | |
# Tetanus vaccine | |
* Vaccines to prevent tetanus often come combined with other | |
vaccines. Abbreviations for such vaccines include: DPT, Tdap, Td, | |
Dt and others. | |
* The DPT vaccine protects against diphtheria, pertussis and | |
tetanus and by 6 months old, babies need a series of 3 injections | |
of this vaccine. | |
* Older children get 3 booster injections of DTP or another | |
combination vaccine to prevent diphtheria and tetanus (such as Td | |
or Dt). | |
* Receiving all 6 doses of these vaccines against tetanus (the | |
series of 3 and then 3 boosters) gives protection from tetanus for | |
decades. | |
* People who did not receive all 6 doses or did not have one within | |
the last 10 years may need a booster vaccine. | |
* Giving the vaccine against tetanus to a pregnant woman whose | |
vaccinations are not up-to-date helps protect both the woman and | |
her newborn baby from tetanus. | |
# Antitetanus immunoglobulin human (Tetanus immune globulin) | |
If a person is not up-to-date with their tetanus vaccination (the | |
series of 3 injections, and at least 3 boosters, or one booster | |
within the past 10 years), then they should be given antitetanus | |
immunoglobulin as soon as possible after getting a wound that might | |
cause tetanus. If giving both the tetanus vaccine and the | |
antitetanus immunoglobulin at the same time, use separate needles and | |
inject in different places on the body. | |
## Side effects | |
There may be pain and tenderness where the injection was given. | |
## Important! | |
Antitetanus immunoglobulin can cause a severe allergic reaction for | |
some people. Always have epinephrine (adrenaline) available in case | |
of an allergic reaction. | |
Some live virus vaccines, including those preventing measles, | |
rubella, and tuberculosis, should not be given for 3 months after | |
someone has received antitetanus immunoglobulin because it may make | |
the other vaccines less effective. | |
## How to use | |
Injection | |
Inject the medicine deep into the muscle. | |
For a wound less than 24 hours old: | |
Inject 250 units one time only. | |
For a wound more than 24 hours old, or a wound that is very likely to | |
be infected with tetanus: | |
Inject 500 units one time only. | |
Also give an antibiotic such as metronidazole OR penicillin G. | |
