Gleeson K, Systemic corticosteroid therapy should be administered promptly to all patients with signs of severe asthma.21 [Evidence level A, systematic review of randomized controlled trials], In patients who can tolerate oral medications, oral corticosteroid therapy is as effective as intravenous therapy.22 Typically, prednisone is given orally in a dosage of 1 to 2 mg per kg once daily (usual maximum: 60 to 80 mg per day) for five to seven days.

Management goals for status asthmaticus are (1) to reverse airway obstruction rapidly through the aggressive use of beta2-agonist agents and early use of corticosteroids, (2) to correct hypoxemia by monitoring and administering supplemental oxygen, and (3) to prevent or treat complications such as pneumothorax and respiratory arrest. J Pak Med Assoc. [6], The mortality risk is also particularly high in patients who delay medical treatment, especially treatment with systemic corticosteroids. 9.
