BOOSTRIX is available in vials and 2 types of prefilled syringes. One type of prefilled syringe has a tip cap which may contain natural rubber latex and a plunger which does not contain latex. The other type has a tip cap and a rubber plunger which contain dry natural latex rubber. Use of these syringes may cause allergic reactions in latex-sensitive individuals. The vial stopper does not contain latex. [See HOW SUPLIED, Storage and Handling.]
Guillain-Barre Syndrome and Brachial Neuritis
If Guillain-Barre syndrome occurred within 6 weeks of receipt of a prior vaccine containing tetanus toxoid, the risk of Guillain-Barre syndrome may be increased following a subsequent dose of tetanus toxoid-containing vaccine, including BOOSTRIX. A review by the Institute of Medicine (IOM) found evidence for a causal relationship between receipt of tetanus toxoid and both brachial neuritis and Guillain-Barre syndrome.1
Progressive or Unstable Neurologic Disorders
Progressive or unstable neurologic conditions (e.g., cerebrovascular events and acute encephalopathic conditions) are reasons to defer vaccination with a pertussis-containing vaccine, including BOOSTRIX. It is not known whether administration of BOOSTRIX to persons with an unstable or progressive neurologic disorder might hasten manifestations of the disorder or affect the prognosis. Administration of BOOSTRIX to persons with an unstable or progressive neurologic disorder may result in diagnostic confusion between manifestations of the underlying illness and possible adverse effects of vaccination.
Persons who experienced an Arthus-type hypersensitivity reaction following a prior dose of a tetanus toxoid-containing vaccine usually have a high serum tetanus antitoxin level and should not receive BOOSTRIX or other tetanus toxoid-containing vaccines unless at least 10 years have elapsed since the last dose of tetanus toxoid-containing vaccine.
As with any vaccine, if administered to immunosuppressed persons, including individuals receiving immunosuppressive therapy, the expected immune response may not be obtained.
Prevention and Management of Acute Allergic Reactions
Prior to administration, the healthcare provider should review the immunization history for possible vaccine sensitivity and previous vaccination-related adverse reactions to allow an assessment of benefits and risks. Epinephrine and other appropriate agents used for the control of immediate allergic reactions must be immediately available should an acute anaphylactic reaction occur.
Carcinogenesis, Mutagenesis, Impairment of Fertility
BOOSTRIX has not been evaluated for carcinogenic or mutagenic potential, or for impairment of fertility.
Use In Specific Populations
Pregnancy Category C
Animal reproduction studies have not been conducted with BOOSTRIX. It is also not known whether BOOSTRIX can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. BOOSTRIX should be given to a pregnant woman only if clearly needed.
Animal fertility studies have not been conducted with BOOSTRIX. In a developmental toxicity study, the effect of BOOSTRIX on embryo-fetal and pre-weaning development was evaluated in pregnant rats. Animals were administered INFANRIX prior to gestation and BOOSTRIX during the period of organogenesis (gestation days 6, 8, 11) and later in pregnancy (gestation day 15), 0.1 mL/rat/occasion (a 45-fold increase compared with the human dose of BOOSTRIX on a body weight basis), by intramuscular injection. No adverse effect on pregnancy and lactation parameters, embryo-fetal or pre-weaning development was observed. There were no fetal malformations or other evidence of teratogenesis noted in this study.
Pregnancy Registry: GlaxoSmithKline maintains a surveillance registry to collect data on pregnancy outcomes and newborn health status outcomes following vaccination with BOOSTRIX during pregnancy. Women who receive BOOSTRIX during pregnancy should be encouraged to contact GlaxoSmithKline directly or their healthcare provider should contact GlaxoSmithKline by calling 1-888-452-9622.
It is not known whether BOOSTRIX is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when BOOSTRIX is administered to a nursing woman.
BOOSTRIX is not indicated for use in children younger than 10 years of age. Safety and effectiveness of BOOSTRIX in this age group have not been established.
In clinical trials, 1,104 subjects 65 years of age and older received BOOSTRIX; of these subjects, 299 were 75 years of age and older. In the US elderly (65 years and older) study, immune responses to tetanus and diphtheria toxoids following BOOSTRIX were non-inferior to the comparator Td vaccine. Antibody responses to pertussis antigens following a single dose of BOOSTRIX in the elderly were non-inferior to those observed with INFANRIX administered as a 3-dose series in infants [see Clinical Studies]. Solicited adverse events following BOOSTRIX were similar in frequency to those reported with the comparator Td vaccine [see ADVERSE REACTIONS].
