Management of asthma during pregnancy.

Asthma is estimated to affect up to 4% of pregnancies. Management of asthma during pregnancy follows the same approach as in the general population. Aggressive treatment should be entertained because asthma under poor control during pregnancy can lead to poor outcomes for the mother and child. The foundations of management are environmental avoidance procedures, proper pharmacologic agents, and specific allergen immunotherapy. For pregnant women with persistent asthma, the use of inhaled cromolyn or inhaled budesonide should be considered as first-line agents. Short-acting beta-agonists can be used as needed in all asthma categories. Other agents such as salmeterol, leukotriene modifiers, newer inhaled corticosteroids, and omalizumab may be considered in women who showed a good response to these agents before pregnancy.
