Before Receiving This Vaccine

Allergies - Tell your doctor if you have ever had any unusual or allergic reaction to diphtheria toxoid, tetanus toxoid, DT, or Td. Also tell your health care professional if you are allergic to any other substances, such as preservatives.

Pregnancy - This vaccine has not been shown to cause birth defects or other problems in humans. Immunization of a pregnant woman can prevent her newborn baby from getting tetanus at birth.

Breast-feeding - This vaccine has not been shown to cause problems in nursing babies.

Children - For infants up to 6 weeks of age, use of DT or Td is not recommended.

For children 7 years of age and older, DT is not recommended. Td is used instead.

Older adults - DT is not recommended. Td is used instead. Td is not expected to cause different side effects or problems in older people than it does in younger adults. However, Td may be slightly less effective in older people than in younger adults.
