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.

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.
