Asthma is a
fairly common health problem for pregnant women, including some women who have
never had it before. During pregnancy, asthma not only affects you, but it can
also cut back on the oxygen your

having asthma will make your pregnancy more difficult or dangerous to you or
your fetus. Pregnant women who have asthma that is properly controlled generally

animal and human studies on the effects of asthma medicines taken during
pregnancy found few risks to the woman or her fetus. It is safer for a pregnant
woman who has asthma to be treated with asthma medicines than for her to have
asthma symptoms and asthma attacks.1 Poor control of
asthma is a greater risk to the fetus than asthma medicines are.1
Budesonide is labeled by the U.S. Food and Drug Administration (FDA) as the
safest inhaled corticosteroid to use during pregnancy. One study found that
low-dose inhaled budesonide in pregnant women seemed to be safe for the mother
and the fetus.3
