Pre-pregnancy, it is important to optimise control of your asthma. During pregnancy you should be closely monitored so that appropriate changes to treatment can be quickly implemented in response to any changed symptoms. In general, asthma inhalers are believed to be safe in pregnancy and the risk of harm to the foetus is much greater from having undertreated and poorly controlled asthma. Roughly one third of women find that their asthma improves during pregnancy, one third find that it stays the same, and the final third find that it worsens.
If you have a serious asthma attack (exacerbation), your doctor may prescribe a short course of oral c orticosteroids. When used orally for less than two weeks, the side effects of corticosteroids are less likely, but when used for many months, they can have a serious and permanent effect. After the severe symptoms of your asthma attack have been successfully treated and controlled, your doctor will work with you to minimize your need for prednisone in the future. Faithfully taking an inhaled corticosteroid every day is the most commonly successful method to do this.
