Effect of Pregnancy on Quantitative Medication Use and Relation to Exacerbations in Asthma

Figure 5

The overall asthma exacerbations were observed less during pregnancy than before and after it. Corticosteroid burst therapy showed a sharp fall at the beginning of pregnancy and slowly increased after delivery. None of the asthma-related hospitalizations, emergency department (ED) visits, and Ventolin nebulizer treatments at the outpatient clinic showed an increasing trend during pregnancy.
