Treatment (including epinephrine 1:1000) for anaphylactoid/hypersensitivity reactions should be present during vaccine use
Not for administration more frequently than every 10 years in patients who experienced a serious arthus-type hypersensitivity reaction following a prior use of tetanus toxoid vaccine even if using for wound management
Syncope, transient visual disturbances, tonic-clonic movements, or weakness reported with use
Use caution if Ghillain-Barre syndrome occurs within 6 weeks of tetanus toxoid administration
Pregnancy and lactation
Pregnancy category: C
Lactation: Excretion in milk unknown; use with caution
Pregnancy categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.
C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.
D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.
X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.
NA: Information not available.
