Boostrix Dosage/Direction for Use

Posology: A single 0.5 ml dose of the vaccine is recommended.
Boostrix can be given in accordance with the current local medical practices for booster vaccination with reduced-content combined diphtheria-tetanus vaccine, when a booster against pertussis is desired.
Boostrix can be administered to pregnant women during the second or the third trimester to provide passive protection of infants against pertussis. (See Indications/Uses, Pregnancy under Use in Pregnancy & Lactation and Pharmacology: Pharmacodynamics under Actions.)
Boostrix may also be administered to adolescents and adults with unknown vaccination status or incomplete vaccination against diphtheria, tetanus and pertussis as part of an immunisation series against diphtheria, tetanus and pertussis (see Pharmacology: Pharmacodynamics under Actions). Based on data in adults, two additional doses of a diphtheria and tetanus containing vaccine are recommended one and six months after the first dose to maximize the vaccine response against diphtheria and tetanus.
Repeat vaccination against diphtheria, tetanus and pertussis should be performed at intervals as per official recommendations (generally 10 years).
Boostrix can be used in the management of tetanus prone injuries in persons who have previously received a primary vaccination series of tetanus toxoid vaccine. Tetanus immunoglobulin should be administered concomitantly in accordance with official recommendations.
Method of administration: Boostrix is for deep intramuscular injection, preferably in the deltoid region (see also Precautions).
