- Asthma during pregnancy is associated with an increased risk of preterm delivery, low birth weight and pre-eclampsia.- This condition may be undertreated due to insufficient knowledge and, in particular, concerns about teratogenic effects of asthma medication among treating healthcare professionals and pregnant women.- The risk of teratogenic effects of inhaled medications (ICS, SABA and LABA) is small. These agents have been used by large groups of patients for many years.- Well-controlled asthma with pharmacological therapy during pregnancy is safer and leads to fewer complications then accepting asthma symptoms and exacerbations.- Preconception care for a woman with asthma who is treated with medication is recommended.
