Is there a pharmacological benefit to administering dexamethasone PO vs IV/IM or is it the preferred route simply to avoid unnecessary sharp use?


The oral route is preferred, when tolerated by the patient. The bioavailability (amount of drug available in the body) is similar and as such, avoids the need for a more invasive administration route. Note that the Croup Medical Directive solely utilizes PO administration.



Bronchoconstriction, Croup, Dexamethasone
