In managing croup, what medication is recommended for all patients, including those with mild disease?

In the management of croup, oral dexamethasone is recommended for all patients, including those with mild disease, because it is an effective corticosteroid that helps reduce inflammation in the airways and alleviate symptoms of stridor and respiratory distress. The single dose is particularly convenient as it simplifies administration, particularly in an outpatient setting, making it feasible for use even in mild cases where hospital admission may not be necessary.

In contrast, the other options involve treatments that are either not universally necessary or specific to more severe cases. Inhaled epinephrine is effective but generally reserved for moderate to severe croup due to its role in rapidly alleviating airway swelling during acute episodes, rather than as a routine treatment for all croup cases. Oral steroids for 5 days may be beneficial, but guidelines emphasize that a single dose of dexamethasone is sufficient for mild cases. Intravenous hydrocortisone is typically only used in severe cases requiring hospitalization, hence it is not indicated for mild disease. Thus, oral dexamethasone stands as the appropriate recommendation across the spectrum of disease severity in croup management.
