Pregnancy and Allergic diseases


 

The effects of pregnancy on asthma have been extensively studied. However, they vary from one individual to another. The following is the rough estimate of the outcome.

  • 1/3: Asthma worsens
  • 1/3: Asthma does not change
  • 1/3: Asthma improves.

The pattern present during the first pregnancy tends to repeat itself during the subsequent ones.

The allergy drugs are classified (see below) according to their tumor-producing effects on the fetus.


CATEGORYANIMAL STUDIESHUMAN STUDIES
ANegativeNegative
BPositiveNegative
CPositiveNot done
DPositivePositive


During pregnancy, the category A and B are preferred. The C drugs can be used if A and B drugs are not adequate for treatment and the potential benefits outweigh the risks.
