Levalbuterol Dosage and Administration Guidelines

Introduction to Levalbuterol

• The American Academy of Allergy, Asthma, and Immunology recommends the dose of levalbuterol for children as 0.075 mg/kg (minimum dose 1.25 mg) every 20 minutes for 3 doses, then 0.075-0.15 mg/kg up to 5 mg every 1-4 hours as needed when administered via nebulizer 1

Nebulizer Solution Dosing

• For nebulizer solution, administer 0.075 mg/kg (minimum dose 1.25 mg) every 20 minutes for 3 doses during acute exacerbations, and for maintenance therapy, use 0.075-0.15 mg/kg up to 5 mg every 1-4 hours as needed 1
• Levalbuterol provides comparable efficacy and safety when administered at one-half the mg dose of racemic albuterol 1

Metered Dose Inhaler (MDI) Dosing

• Children should receive 4-8 puffs every 20 minutes for 3 doses, then every 1-4 hours as needed, following the same dosing pattern as albuterol MDI 1, 2
• Using a valved holding chamber (spacer) with proper technique is as effective as nebulized therapy for mild-to-moderate exacerbations 1

Age-Specific Considerations

• For children under 4 years, levalbuterol nebulizer solution should be used with caution due to limited data available 3

Administration Techniques

• For optimal delivery via nebulizer, dilute aerosols to a minimum of 3 mL at a gas flow of 6-8 L/min 1
• Ipratropium bromide may be mixed with levalbuterol in the same nebulizer for severe exacerbations 1

Monitoring and Safety Considerations

• Monitor for common beta-agonist side effects including tachycardia, skeletal muscle tremor, hypokalemia, headache, and hyperglycemia 3
• Increasing use or lack of expected effect indicates diminishing asthma control and need for medical attention 2
• Regular use exceeding twice weekly for symptom control indicates poor asthma control and need for controller medication adjustment 2
