Asthalin (Salbutamol) MDI Dosage in Children with Asthma

For children 4 years and older with asthma, the recommended Asthalin (Salbutamol) MDI dosage is 2 puffs (90 mcg/puff) every 4-6 hours as needed for relief of bronchospasm. 1

Standard Dosing for Maintenance and Relief

  • For children 4 years and older: 2 puffs every 4-6 hours as needed for bronchospasm relief 1
  • For exercise-induced bronchospasm prevention: 2 puffs 15-30 minutes before exercise 1
  • Increasing use or lack of expected response may indicate worsening asthma control requiring reassessment 1

Dosing During Asthma Exacerbations

Mild to Moderate Exacerbations:

  • 4-8 puffs every 20 minutes for 3 doses, then every 1-4 hours as needed 2
  • MDI with valved holding chamber (spacer) is as effective as nebulized therapy when used with proper technique 2

Severe Exacerbations:

  • 4-8 puffs every 20 minutes for 3 doses, then every 1-4 hours as needed 2
  • Consider adding ipratropium bromide (4-8 puffs every 20 minutes for up to 3 hours) for severe exacerbations 2

Administration Technique

  • Use a valved holding chamber (spacer) for all children to improve medication delivery 2
  • For children under 4 years, a face mask should be attached to the spacer 2
  • Proper cleaning of the mouthpiece is essential to prevent medication buildup and blockage 1
  • Wash and dry the mouthpiece thoroughly at least once a week 1

Important Considerations

  • Increasing need for Asthalin (more than twice weekly) indicates inadequate asthma control and may require adjustment of controller medications 3
  • During exacerbations, MDI with spacer can be as effective as nebulizer therapy when used at appropriate doses (usually 1/4th of nebule dosing) 4
  • For children under 4 years of age, safety and efficacy data are limited 1

Monitoring and Follow-up

  • Monitor for side effects including tachycardia, tremor, and hyperglycemia, especially with higher or frequent dosing 5
  • If symptoms worsen despite proper use of medication, seek immediate medical attention 3
  • Regular follow-up is essential to assess response to therapy and adjust treatment as needed 2

Common Pitfalls to Avoid

  • Overreliance on rescue medication (Asthalin) without addressing underlying inflammation 3
  • Poor inhaler technique leading to inadequate drug delivery 3
  • Failure to use a spacer device, especially in young children 2
  • Not recognizing when to escalate treatment during worsening symptoms 2

Remember that Asthalin (Salbutamol) is primarily a rescue medication for symptom relief. If a child requires frequent use, this indicates the need for review of their controller medication regimen and overall asthma management plan 3.
