Corticosteroid Treatment for Asthma Exacerbations
For asthma exacerbations, systemic corticosteroids should be administered promptly, with oral prednisone (or equivalent) as the preferred first-line treatment for most patients, given at a dose of 40-60mg daily for 3-10 days without tapering. 1
Systemic Corticosteroid Recommendations
Route of Administration
- Oral administration is preferred for most patients due to equivalent efficacy to intravenous route with less invasiveness 1
- Intravenous administration should be reserved for patients who cannot take oral medications or have severe exacerbations 1, 2
- For those at high risk of non-adherence, intramuscular depot injections may be considered as an alternative 1
Dosing Guidelines
- Adult dosing: 40-60mg of prednisone (or equivalent) daily 1, 2
- Pediatric dosing: 1-2 mg/kg/day of prednisone, prednisolone, or methylprednisolone 2
- Duration: 3-10 days is typically sufficient 1
- Tapering is generally not necessary for short courses of therapy 2
Timing of Administration
- Early administration of systemic corticosteroids is crucial as it speeds resolution of airflow obstruction and reduces post-ED relapse rates 1
- For moderate to severe exacerbations, administer corticosteroids within the first hour of treatment 1
Severity-Based Treatment Approach
Mild Exacerbations
- Oral corticosteroids may be indicated, especially if response to initial bronchodilator therapy is inadequate 1
- Five guidelines recommend oral corticosteroids even for mild exacerbations 1
Moderate Exacerbations
- Oral corticosteroids are strongly recommended (11 guidelines support this approach) 1
- Should be administered early in treatment course 1
Severe Exacerbations
- Systemic corticosteroids are essential components of treatment 1
- Intravenous administration may be preferred in patients with potential absorption issues 1, 2
- Seven guidelines specifically recommend IV corticosteroids for severe exacerbations 1
Additional Treatment Considerations
Concurrent Medications
- Systemic corticosteroids should be used alongside inhaled β2-agonists and oxygen as appropriate 1
- Patients already on inhaled corticosteroids should continue this therapy while taking systemic corticosteroids 1
- Consider adding ipratropium bromide for additional bronchodilation, particularly in severe exacerbations 1
Post-Discharge Management
- Prescribe sufficient medication to continue therapy for 3-10 days after discharge 1
- Consider initiating or continuing inhaled corticosteroids at discharge 1
- Schedule follow-up appointment to assess need for additional corticosteroid treatment 1
Common Pitfalls and Caveats
- Delaying corticosteroid administration can worsen outcomes and increase hospitalization rates 1
- Unnecessarily prolonged courses (>10 days) do not provide additional benefit and increase risk of side effects 1, 2
- Tapering short courses (5-10 days) of systemic corticosteroids is unnecessary and does not prevent relapse 2
- Relying solely on inhaled corticosteroids during acute exacerbations is insufficient; systemic therapy is required 1
- Antibiotics should not be routinely prescribed unless there is strong evidence of bacterial infection 1
Special Populations
- Pregnant patients: Uncontrolled asthma poses greater risk than corticosteroid treatment; use lowest effective dose 1
- Pediatric patients: Dosing should be based on severity rather than age, typically 1-2 mg/kg/day 2
- Patients with diabetes: Monitor blood glucose levels closely as corticosteroids can cause hyperglycemia 2
