AbstractAsthma and rhinitis frequently complicate pregnancy. The course of asthma may be adversely altered by gestation, placing the mother and fetus at risk. Therefore, pregnant patients with persistent asthma require an aggressive asthma management plan that includes environmental control measures and the use of long-term controller medications. Inhaled corticosteroids (ICSs) are the preferred long-term controller medication for persistent asthma, based on efficacy. However, safety concerns regarding corticosteroids may cause physicians or patients to seek an alternate, less effective treatment during pregnancy. The Food and Drug Administration's pregnancy category ratings are based on animal and human safety data. Because ICSs were previously rated pregnancy category C (i.e., with human studies lacking and animal studies either lacking or positive for fetal risk), other asthma controllers, such as cromolyn and nedocromil, that carry a pregnancy category B rating (i.e., showing no evidence of fetal risk in humans or animal studies negative for fetal risk) appeared to be more desirable for use during pregnancy. One ICS, budesonide, was reclassified as pregnancy category B based on human data supporting its use during pregnancy. In moderate and severe persistent asthma, add-on therapy may be considered, including long-acting beta2-adrenergic agonists, leukotriene receptor antagonists, and theophylline. Because rhinitis may adversely affect quality of life and the course of asthma, recommendations for aggressive management also apply.
