Yes, inhaled corticosteroids should absolutely be given together with oral prednisone during asthma exacerbations.
Inhaled corticosteroids (ICS) can and should be started at any point during the treatment of an asthma exacerbation, including when oral corticosteroids are being administered 1. This is explicitly stated in the NAEPP guidelines and represents standard practice.
Key Evidence Supporting Combined Use
The 2009 NAEPP Expert Panel guidelines clearly state: "ICSs can be started at any point in the treatment of an asthma exacerbation" 1. This recommendation removes any ambiguity about combining these therapies.
Research supports this approach, demonstrating that:
- ICS provide additional benefit when used in conjunction with prednisone in acute severe asthma 2
- Patients using high-dose inhaled budesonide combined with standard oral prednisone experienced approximately 50% reduction in relapse rates compared to oral prednisone alone 3
Practical Implementation
During an acute exacerbation:
- Start or continue ICS immediately alongside oral prednisone
- Do not wait to initiate ICS therapy
- The typical oral prednisone regimen is 40-80 mg/day (adults) or 1-2 mg/kg/day (children, max 60 mg/day) until PEF reaches 70% of predicted 1
- ICS can be started at medium to high doses depending on severity
After the exacerbation resolves:
- Continue ICS as maintenance therapy
- The oral prednisone course typically lasts 3-10 days 1
- For courses under 1 week, no taper is needed, especially if the patient is already on ICS 1
Rationale for Combined Therapy
The mechanisms are complementary rather than redundant:
- Oral corticosteroids provide rapid systemic anti-inflammatory effects for acute control
- ICS deliver targeted airway anti-inflammatory effects and help prevent relapse
- Starting ICS during the exacerbation ensures continuity of anti-inflammatory therapy as oral steroids are discontinued
Important Caveats
There is no contraindication or harmful interaction between ICS and oral corticosteroids. The FDA labeling for prednisone does not list ICS as an interaction 4. The concern should be about cumulative corticosteroid burden over time, not acute combined use during exacerbations.
The 2020 NAEPP guidelines emphasize that ICS should be part of the treatment algorithm at every step, including during acute management 5. This represents the current standard of care for asthma exacerbations.
