Is it safe to use inhaled corticosteroids in pregnancy?

Question: A healthy woman with mild to moderate asthma came to my clinic today after learning that she was pregnant. She inquired about continuing her inhaled corticosteroid (ICS) medication and whether there would be any risks to her unborn child if she were to do so. What would you advise?

Answer: Given the published evidence, ICSs should be continued throughout pregnancy at low to moderate doses sufficient to control asthma symptoms and prevent exacerbations.
