From the Guidelines
Albuterol (also known as salbutamol) is a good cost-effective rescue inhaler for managing acute asthma symptoms or bronchospasm. It typically costs between $5-30 per inhaler with insurance or discount programs. The standard dose is 1-2 puffs (90-180 mcg) every 4-6 hours as needed for symptoms, with each inhaler containing approximately 200 doses. For acute symptoms, you can use up to 4-6 puffs separated by a few minutes, but frequent need for more than 2 puffs may indicate poor asthma control requiring medical attention. Albuterol works as a short-acting beta-2 agonist (SABA) that relaxes airway smooth muscles within minutes, providing quick relief of wheezing, shortness of breath, and chest tightness.
Key Considerations
- The proper technique involves shaking the inhaler, exhaling fully, placing the mouthpiece between lips, inhaling slowly while activating the inhaler, holding breath for 10 seconds, then waiting 30-60 seconds before the next puff if needed.
- Using a spacer device can improve medication delivery and reduce side effects like tremor, increased heart rate, and anxiety, as noted in the guidelines for managing asthma 1.
- Generic versions of albuterol are typically the most economical option while maintaining effectiveness.
- It's also important to consider the environmental impact of inhalers, with dry powder inhalers (DPIs) generally having a lower carbon footprint than metered-dose inhalers (MDIs), as discussed in a study on local variation in low carbon footprint inhalers 1.
Patient Education
- Patients should be educated on the proper use of their inhaler, including the importance of using a spacer device if recommended by their healthcare provider.
- Patients should also be aware of the potential side effects of albuterol and the importance of seeking medical attention if they experience frequent or severe symptoms.
- As noted in a study on guidelines for managing asthma, patient education and proper inhaler technique are crucial for effective asthma management 1.

From the Research
Cost-Effective Rescue Inhalers
- A study published in Chest in 2002 2 found that albuterol administered by metered-dose inhaler (MDI) and spacer is a cost-effective alternative to nebulization in adults with acute asthma.
- The study compared the efficacy of albuterol by MDI and spacer with albuterol by nebulizer in 2,342 emergency department visits and found that the MDI/spacer group had a statistically greater improvement in peak flow rates and spent less time in the emergency department.
- Another study published in Chest in 1997 3 compared the efficacy of three delivery systems for albuterol: jet nebulizer, metered dose inhaler with spacer, and dry powder inhaler, and found that all three delivery systems were effective in treating acute severe asthma.
Comparison of Delivery Systems
- A study published in Chest in 1993 4 compared the dose-response relationship to albuterol by wet nebulization or metered dose inhaler in acute asthma and found that albuterol by metered dose inhaler provided similar bronchodilation to that achieved by wet nebulization.
- A study published in Annals of allergy, asthma & immunology in 2001 5 compared the efficacy, safety, and tolerability of formoterol dry powder inhaler with albuterol metered-dose inhaler in patients with mild to moderate persistent asthma and found that formoterol was more effective than albuterol in improving lung function and reducing asthma symptoms.
Safety of Albuterol Multidose Dry Powder Inhaler
- A study published in The Journal of asthma in 2016 6 evaluated the safety of albuterol multidose dry powder inhaler in patients with persistent asthma and found that the safety profile of albuterol MDPI was comparable with placebo MDPI and consistent with the well-characterized profile of albuterol in patients with asthma.
