What is a common treatment for croup?

Oral corticosteroids are a common treatment for croup because they reduce inflammation in the airways, helping to alleviate symptoms such as stridor and respiratory distress. Croup, often caused by viral infection, results in swelling of the larynx and surrounding tissues, which can lead to breathing difficulties. Corticosteroids help minimize this inflammation, leading to improved airflow and reduced symptoms.

Antibiotics are not effective against viral infections, which are the primary cause of most cases of croup. Inhaled bronchodilators may be used in cases of wheezing or when there is bronchospasm, but they do not specifically target the inflammation associated with croup. Antihistamines are typically used for allergic reactions or conditions like allergic rhinitis and are not indicated for viral croup, which involves different inflammatory processes. Thus, oral corticosteroids stand out as the preferred treatment to address the underlying inflammation in croup.
