Details with Side Effects
If any of the following events occur within the specified period after administration of a whole-cell pertussis or acellular pertussis-containing vaccine, the decision to administer Pentacel (tetanus toxoid conjugate) vaccine or any pertussis-containing vaccine should be based on careful consideration of potential benefits and possible risks. (19) (See DOSAGE AND ADMINISTRATION.)
- Temperature of ≥ 40.5°C ( ≥ 105°F) within 48 hours, not attributable to another identifiable cause.
- Collapse or shock-like state (hypotonic-hyporesponsive episode [HHE]) within 48 hours.
- Persistent, inconsolable crying lasting 3 hours within 48 hours.
- Seizure with or without fever within ≥ 3 days.
A review by the Institute of Medicine (IOM) found evidence for a causal relation between tetanus toxoid and brachial neuritis, Guillain-Barré syndrome and anaphylaxis. (20) If Guillain-Barré syndrome occurred within 6 weeks of receipt of a prior vaccine containing tetanus toxoid, the decision to give Pentacel (tetanus toxoid conjugate) vaccine or any vaccine containing tetanus toxoid should be based on careful consideration of the potential benefits and possible risks. (19)
Vaccination with Pentacel (tetanus toxoid conjugate) vaccine may not protect all individuals.
Before administration of Pentacel (tetanus toxoid conjugate) vaccine, the patient's current health status and medical history should be reviewed in order to determine whether any contraindications exist and to assess the benefits and risks of vaccination. (See CONTRAINDICATIONS and WARNINGS).
For infants or children at higher risk for seizures than the general population, an appropriate antipyretic may be administered (in the dosage recommended in its prescribing information) at the time of vaccination with an acellular pertussis-containing vaccine (including Pentacel (tetanus toxoid conjugate) vaccine) and for the following 24 hours, to reduce the possibility of post-vaccination fever.
