Summary: For children brought to emergency care for an acute asthma exacerbation, giving single-dose dexamethasone + an inhaled beta-agonist may lead to the same rates of treatment response and hospitalizations as treatment with a 3-day course of prednisolone + an inhaled beta-agonist (although patients given dexamethasone might have a slightly increased need for subsequent oral steroids within the following 2 weeks).
