Are asthma medications harmful to the fetus?
Asthma medications do not appear to be associated with increased congenital malformations. Theoretically, however, some of the asthma medications may contribute to an increased risk to the fetus. Observations in hundreds of pregnancies in women with asthma have demonstrated that most anti-asthmatic medications are appropriate for use in pregnancy. The risks of uncontrolled asthma appear to be greater than the risks of necessary asthma medications. However, any oral medication should be avoided unless necessary for the control of symptoms. In general, aerosol and sprays are preferred therapy.
