Passage: Corticosteroids, such as dexamethasone and budesonide, have been shown to improve outcomes in children with all severities of croup. Significant relief is obtained as early as two hours after administration. While effective when given by injection, or by inhalation, giving the medication by mouth is preferred. A single dose is usually all that is required, and is generally considered to be quite safe. Dexamethasone at doses of  0.15, 0.3 and 0.6 mg/kg appear to be all equally effective.

Question: What medication is able to be administered both by injection and by breathing it in?
Dexamethasone
