What inhaled corticosteroid (ICS) is recommended for a 4-year-old child in Alberta?

Inhaled Corticosteroid Selection for a 4-Year-Old Child with Asthma in Alberta

For a 4-year-old child in Alberta, budesonide inhalation suspension (nebulizer solution) is the recommended inhaled corticosteroid as it is the only ICS with FDA-approved labeling for children under 4 years of age. 1

Recommended Options

First-line Option:

• Budesonide inhalation suspension (nebulizer solution)
  • Dosing: 0.25-0.5 mg once daily or divided twice daily 1, 2
  • Administration: Via compressed air driven jet nebulizers only (not for use with ultrasonic devices) 2
  • FDA approved for children 1-8 years of age 1, 2

Alternative Option (for children 4 years and older):

• Fluticasone propionate HFA/MDI
  • Dosing: 88 mcg twice daily (176 mcg/day) for low dose therapy 1
  • Administration: With spacer device and face mask 1
  • FDA approved for children 4 years and older 1

Dosing Considerations

Budesonide Nebulizer Solution:

• Starting dose:
  • For children not on previous therapy: 0.25 mg once daily 2
  • For children previously on bronchodilators alone: 0.25 mg twice daily or 0.5 mg once daily 2
  • For children previously on inhaled corticosteroids: 0.25-0.5 mg twice daily 2
  • For children previously on oral corticosteroids: 0.5 mg twice daily 2

Administration Technique

• Children under 4 years generally require delivery of ICS through a face mask that should fit snugly over nose and mouth 1
• Avoid nebulizing in the eyes 1
• Wash face after each treatment to prevent local side effects 1

Monitoring and Follow-up

• Growth monitoring: Carefully monitor length/height in children treated with ICS 1
• Efficacy assessment: If a clear benefit is not observed within 4-6 weeks, consider alternative therapies or diagnoses 1
• Step-down therapy: Once control is achieved, carefully titrate to the minimum dose required to maintain control 1

Important Considerations

Advantages of Budesonide for Young Children:

• Only ICS with FDA approval for children under 4 years 1
• Compatible with albuterol, ipratropium, and levalbuterol nebulizer solutions in the same nebulizer 1
• Established efficacy and safety profile in this age group 3

Potential Adverse Effects:

• Local effects: Cough, dysphonia, oral thrush (candidiasis) 1
• Systemic effects at high doses: Adrenal suppression, growth effects 1, 4
• Most common adverse events: Respiratory infection, rhinitis, coughing 2

Special Precautions:

• For intermittent use in children with recurrent wheezing triggered by respiratory infections, budesonide 1 mg twice daily for 7 days at the first sign of respiratory tract infection can be considered 1
• Use only jet nebulizers as ultrasonic nebulizers are ineffective for suspensions 1

Clinical Decision Algorithm

1. Confirm diagnosis: Assess symptoms, frequency of wheezing episodes, and risk factors
2. Select appropriate ICS:
   • For a 4-year-old: Budesonide nebulizer solution is first choice
   • If delivery by MDI is preferred and child is exactly 4 years: Consider fluticasone HFA with spacer
3. Determine appropriate starting dose based on previous therapy and symptom severity
4. Reassess in 4-6 weeks to determine response
5. Adjust therapy as needed:
   • If good response: Continue and consider step-down after 3 months of control
   • If inadequate response: Check technique, adherence, and consider step-up therapy

Remember that the goal of therapy is to use the lowest effective dose to maintain control and minimize potential side effects, particularly on growth.
