Use |
|
Selective induction of active immunity against tetanus in selected patients.
Note: Tetanus and diphtheria toxoids for adult use (Td) is the preferred
immunizing agent for most adults and for children after their seventh birthday.
Young children should receive trivalent DTwP or DTaP
(diphtheria/tetanus/pertussis - whole cell or acellular), as part of their
childhood immunization program, unless pertussis is contraindicated, then TD is
warranted. |

Contraindications |
|
Hypersensitivity to tetanus toxoid or any component (may use the fluid
tetanus toxoid to immunize the rare patient who is hypersensitive to aluminum
adjuvant); avoid use with chloramphenicol or if neurological signs or symptoms
occurred after prior administration; poliomyelitis outbreaks require deferral of
immunizations; acute respiratory infections or other active infections may
dictate deferral of administration of routine primary immunizing but not
emergency doses |
|
|
Warnings/Precautions |
|
Not equivalent to tetanus toxoid fluid; the tetanus toxoid adsorbed is the
preferred toxoid for immunization and Td, TD or DTaP/DTwP are the preferred
adsorbed forms; avoid injection into a blood vessel; have epinephrine (1:1000)
available; not for use in treatment of tetanus infection nor for immediate
prophylaxis of unimmunized individuals; immunosuppressive therapy or other
immunodeficiencies may diminish antibody response, however it is recommended for
routine immunization of symptomatic and asymptomatic HIV-infected patients;
deferral of immunization until immunosuppression is discontinued or
administration of an additional dose >1 month after treatment is recommended;
allergic reactions may occur; epinephrine 1:1000 must be available; use in
pediatrics should be deferred until >1 year of age when a history of a CNS
disorder is present; elderly may not mount adequate antibody titers following
immunization |
|
|
Adverse
Reactions |
|
>10%: Local: Induration/redness at injection site
1% to 10%:
Central nervous system: Chills, fever
Local: Sterile abscess at injection site
Miscellaneous: Allergic reaction
<1%: Fever >103°F, malaise, neurological
disturbances, blistering at injection site, Arthus-type hypersensitivity
reactions |
|
|
Drug
Interactions |
|
Decreased response: If primary immunization is started in individuals
receiving an immunosuppressive agent or corticosteroids, serologic testing may
be needed to ensure adequate antibody response; concurrent use of TIG and
tetanus toxoid may delay the development of active immunity by several
days |
|
|
Stability |
|
Refrigerate, do not freeze |
|
|
Mechanism of
Action |
|
Tetanus toxoid preparations contain the toxin produced by virulent tetanus
bacilli (detoxified growth products of Clostridium tetani). The toxin
has been modified by treatment with formaldehyde so that it has lost toxicity
but still retains ability to act as antigen and produce active immunity; the
aluminum salt, a mineral adjuvant, delays the rate of absorption and prolongs
and enhances its properties; duration ~10 years. |
|
|
Pharmacodynamics/Kinetics |
|
Duration of immunization following primary immunization: ~10
years |
|
|
Usual Dosage |
|
Adults: I.M.:
Routine booster doses are recommended only every 5-10 years
|
|
|
Administration |
|
Inject intramuscularly in the area of the vastus lateralis (midthigh
laterally) or deltoid |
|

Patient
Information |
|
A nodule may be palpable at the injection site for a few weeks. DT, Td and T
vaccines cause few problems; they may cause mild fever or soreness, swelling,
and redness where the shot was given. These problems usually last 1-2 days, but
this does not happen nearly as often as with DTP vaccine. Sometimes, adults who
get these vaccines can have a lot of soreness and swelling where the shot was
given. |

|
Dosage Forms |
|
Injection, adsorbed:
Tetanus 10 Lf units per 0.5 mL dose (0.5 mL, 5 mL) |
