Low Dose Inhaled Corticosteroid (ICS) Initial Treatment Plan

The recommended initial dose for patients requiring low-dose inhaled corticosteroids (ICS) is 80-240 mcg/day for fluticasone propionate or 180-600 mcg/day for budesonide DPI in adults and adolescents, administered as a daily controller medication. 1

Initial Dosing Recommendations

  • For adults and adolescents (≥12 years), low-dose ICS is defined as 80-240 mcg/day for fluticasone propionate and 180-600 mcg/day for budesonide DPI 1
  • For children 5-11 years, low-dose ICS is defined as 88-176 mcg/day for fluticasone propionate and 180-400 mcg/day for budesonide DPI 1
  • For children under 4 years with persistent asthma, budesonide nebulizer suspension (0.25-0.5 mg) is the only FDA-approved ICS 1
  • Daily low-dose ICS is the preferred controller medication for Step 2 of asthma management according to the 2020 Global Initiative for Asthma (GINA) guidelines 2

Treatment Plan Algorithm

  1. Initial Assessment and Prescription:

    • Start with low-dose ICS for patients with persistent asthma 1
    • Ensure proper inhaler device selection and technique instruction 1
    • Use spacers or valved holding chambers when appropriate 1
    • Instruct patients to rinse mouth after ICS use to reduce local side effects 1
  2. Follow-up and Monitoring:

    • Assess asthma control after 1-3 months of initial treatment 1
    • Monitor for potential side effects, especially with higher doses or prolonged use 1
    • Evaluate symptom control, lung function, and exacerbation risk 2
  3. Treatment Adjustment:

    • If asthma is not well-controlled:
      • Check adherence, inhaler technique, and environmental control measures 1
      • Consider stepping up to medium-dose ICS or adding a long-acting beta agonist (LABA) 2, 1
    • If asthma is well-controlled for 3 months, consider stepping down treatment 2

Alternative Treatment Options

  • As-needed low-dose ICS-formoterol can be considered as an alternative to daily ICS in some patients 2
  • Leukotriene receptor antagonists (LTRAs) like montelukast are appropriate alternatives for mild persistent asthma in patients unable or unwilling to use ICS 3
  • For patients with mild asthma at step 2, use of ICS with each dose of as-needed SABA results in asthma control that is noninferior to daily ICS while reducing total ICS exposure 2

Important Considerations and Pitfalls

  • Low-dose ICS achieves 80-90% of the maximum obtainable therapeutic benefit in adult asthma across the spectrum of severity 4
  • Patients with mild to moderate disease achieve similar levels of asthma control on low doses of fluticasone (200 mcg/day or less) as they do on high doses (500 mcg/day or greater) 5
  • Undertreatment, poor inhaler technique, inadequate follow-up, and neglecting comorbidities can lead to poor asthma control and increased exacerbation risk 1
  • The incidence of oral candidiasis is ≤8% in patients treated with fluticasone propionate ≤250 mcg twice daily 6
  • There is no evidence of clinically significant hypothalamo-pituitary-adrenal (HPA) axis suppression with fluticasone propionate ≤250 mcg twice daily 6

Special Populations

  • For oral steroid-dependent patients, higher doses of ICS may be required to reduce systemic corticosteroid use 2
  • Combination therapy for children younger than 12 years of age with moderate persistent asthma is based on extrapolations from studies in older children and adults 2
  • In young children, proper device selection and delivery technique are particularly important for treatment effectiveness 1
