Prescription for Mild Persistent Asthma
For mild persistent asthma, prescribe a low-dose inhaled corticosteroid (ICS) as the preferred daily controller medication, combined with a short-acting beta-2 agonist (SABA) as needed for quick relief. 1
Primary Controller Therapy
The cornerstone of treatment is low-dose ICS taken daily (Step 2 care). This is the most effective single long-term control medication for reducing exacerbations, controlling symptoms, and reducing airway inflammation 2, 1. Examples include:
- Fluticasone 88-264 mcg/day (2 puffs of 44 mcg twice daily)
- Beclomethasone ≤500 mcg/day
- Budesonide 180-600 mcg/day
Use with a spacer device to increase lung deposition and reduce oral side effects 1.
Quick-Relief Medication
Add albuterol (SABA) 2 puffs every 4-6 hours as needed for acute symptoms 1.
Critical monitoring point: If the patient uses SABA more than 2 days per week for symptom relief (excluding pre-exercise use), this signals inadequate asthma control and requires stepping up therapy 1.
Alternative Options (If Patient Cannot/Will Not Use ICS)
If the patient refuses or cannot tolerate ICS, consider these second-line alternatives 2, 1:
- Montelukast 10 mg once daily (ages >12 years) - easier compliance, taken orally
- Zafirlukast 20 mg twice daily (ages ≥7 years)
- Cromolyn or nedocromil (less preferred)
- Theophylline (requires serum monitoring - least preferred)
Important caveat: While leukotriene receptor antagonists offer convenience and good compliance, they are explicitly not preferred over ICS for initial therapy 2, 1. One study showed similar patient-oriented outcomes between montelukast and low-dose ICS in children, with fewer respiratory infections in the montelukast group, but ICS remains guideline-preferred 1.
Newer Evidence Consideration
For adults and adolescents ≥12 years with mild persistent asthma, the 2020 NHLBI guidelines conditionally recommend an alternative approach: as-needed ICS-SABA used concomitantly (taken together when symptoms occur) rather than daily ICS 3. However, this is a conditional recommendation with moderate evidence, and daily low-dose ICS remains a valid option.
What NOT to Prescribe
Never prescribe SABA alone as monotherapy for persistent asthma - this does not address underlying inflammation and increases risk of exacerbations 1.
Never prescribe long-acting beta-agonists (LABAs) as monotherapy - they should only be used in combination with ICS for more severe disease (Step 3 or higher) 2, 1.

Follow-Up Instructions
Schedule follow-up in 2 weeks to assess initial response. If symptoms are not controlled, step up to Step 3 therapy (low-dose ICS-LABA combination or medium-dose ICS) 1. Provide written asthma action plan with green/yellow/red zones for self-management 1.
