Asthma’s progression during pregnancy is highly variable. Improvement in symptoms can be seen in 18%–34% of patients, while worsening of symptoms can be seen in 20%–42% of patients. Acute exacerbations of asthma are most frequently seen late in the second trimester and are associated with a viral upper-respiratory infection. An acute exacerbation of asthma in the parturient can result in increased risk of maternal mortality, preterm delivery, and low-birth-weight infants. In patients with moderate to severe asthma, good control with inhaled corticosteroids, such as budesonide, is a cornerstone of reducing morbidity and mortality. The four components of care for the asthmatic patient are education, control of environmental factors, medications, and monitoring of symptoms.
