Corticosteroids are considered the first-line therapy (SOR C). Intravenous immunoglobulin and rituximab
have also been used as first-line agents
pertussis

B. Oral prednisone for 5 days
C. Daily inhaled fluticasone (Flovent)
D. Hospital admission for intravenous methylprednisolone sodium succinate (Solu-Medrol)
E. No corticosteroids at this time

His vital signs do not indicate a
serious condition at this time, so he can be treated as an outpatient. Since he is already on a reasonable
dose of an inhaled bronchodilator/anticholinergic combination, he should be treated with an oral antibiotic
