Recommended Dosage and Usage of Symbicort (budesonide-formoterol) for Asthma and COPD
For patients with asthma or COPD, Symbicort (budesonide-formoterol) should be administered as 2 inhalations twice daily, with specific strength determined by disease severity and patient age. 1
Dosage for Asthma
Adults and Adolescents (12 years and older):
- 2 inhalations of Symbicort 80/4.5 or 160/4.5 twice daily, with strength selection based on asthma severity or current level of symptom control 1
- Maximum recommended dosage is 2 inhalations of Symbicort 160/4.5 twice daily 1
- Improvement in asthma control may begin within 15 minutes of administration, though maximum benefit may take 2 weeks or longer 1
Children (6 to less than 12 years):
- 2 inhalations of Symbicort 80/4.5 twice daily 1
Adjusting Therapy:
- For patients not responding adequately to starting dose after 1-2 weeks with Symbicort 80/4.5, consider replacing with Symbicort 160/4.5 for additional asthma control 1
- If a previously effective dosage fails to provide adequate control, reevaluate the therapeutic regimen and consider additional options (higher strength, additional inhaled corticosteroid, or oral corticosteroids) 1
- For breakthrough symptoms between doses, patients should use a short-acting beta2-agonist for immediate relief 1
Dosage for COPD
- For all COPD patients: 2 inhalations of Symbicort 160/4.5 twice daily 1
- For shortness of breath between doses, use an inhaled short-acting beta2-agonist for immediate relief 1
Important Administration Considerations
- More frequent administration or higher number of inhalations than prescribed (more than 2 inhalations twice daily) is not recommended due to increased risk of adverse effects with higher formoterol doses 1
- Patients using Symbicort should not use additional long-acting beta2-agonists (LABAs) for any reason 1
- In COPD, Symbicort is recommended for patients with severe COPD (FEV1 <50% of predicted value) and a history of repeated exacerbations who have significant symptoms despite regular therapy with long-acting bronchodilators 2
Clinical Benefits and Considerations
- In asthma, Symbicort has been shown to not only improve lung function and decrease symptoms but also reduce the number of mild and severe exacerbations 3
- Fixed combination therapy with Symbicort is more effective than inhaled corticosteroids alone and at least as effective as both components administered separately 4
- In COPD, Symbicort improves lung function, reduces exacerbation rates, improves symptom scores, and enhances health status compared to placebo and generally compared to individual monotherapies 2
- Adding Symbicort to tiotropium bromide therapy has been shown to be significantly more effective than tiotropium alone in COPD management 2
Caution and Monitoring
- Monitor for common adverse effects, which are typically mild and related to expected inhaled corticosteroid and long-acting beta2-agonist class effects 4
- In COPD patients, be aware of increased risk of pneumonia with ICS-containing regimens 3
- For patients with asthma, ensure Symbicort is always used with an inhaled corticosteroid component to prevent potential risks associated with LABA monotherapy 3
