Dexamethasone is better than prednisone/prednisolone for asthma exacerbations
Use the PO tablets rather than the liquid
They can be crushed with Kool-Aid mix and then dissolved to drink
Magnesium can be used if not adequate improvement after albuterol/ipratropium, dexamethasone.
Other options (last ditch): epinephrine, terbutaline – very poorly tolerated by children!
