Most pregnant women with asthma have a safe pregnancy, labor, and delivery. If you experienced severe asthma attacks before you got pregnant, you may have severe attacks during pregnancy. In general, the treatment plan your doctor had you on before you got pregnant should continue to help. This would include medications prescribed for asthma before or during pregnancy.

During a pregnancy, oxygen use increases by about 25%. This is because your baby needs that oxygen in order to grow and develop. That’s why asthma treatment is so important while you’re pregnant. Asthma medication (such as terbutaline) and steroids (such as hydrocortisone or methylprednisolone) can be used during pregnancy. Aminophylline or theophyline are also safe to use.
