When are systemic corticosteroids typically used in asthma management?

Systemic corticosteroids are primarily utilized during acute asthma exacerbations due to their potent anti-inflammatory properties. During an exacerbation, the airways become inflamed and narrowed, leading to increased symptoms such as wheezing, shortness of breath, and chest tightness. Systemic corticosteroids, administered orally or intravenously, act quickly to reduce inflammation within the airways, thereby improving airflow and alleviating symptoms.

In contrast, while corticosteroids can be beneficial for long-term management, they are typically used in inhaled forms for regular maintenance therapy rather than systemic forms, which are more suited for immediate relief during exacerbations. Mild symptoms often do not require systemic corticosteroids; instead, inhaled short-acting bronchodilators are generally sufficient. Lastly, corticosteroids are not only indicated for allergic reactions; they are a critical component of managing severe inflammatory conditions, such as asthma exacerbations. Thus, the use of systemic corticosteroids is specifically targeted during acute exacerbations to provide rapid control of severe asthma symptoms.
