Albuterol Efficacy for Cough Due to Upper Respiratory Infection in Adults
Several studies have examined whether albuterol is effective in treating cough caused by upper respiratory infections (URIs) in adults. One randomized controlled trial found that oral albuterol did not significantly improve cough severity, reduce sleepless nights, or help patients return to normal activities compared to placebo. Additionally, those taking albuterol reported more side effects like shakiness and nervousness, suggesting that oral albuterol should not be used for acute, nonspecific cough in adults without underlying lung disease .
However, other research focusing on patients with acute bronchitis—a common cause of cough during URIs—showed that albuterol delivered by metered-dose inhaler (MDI) reduced the likelihood of persistent cough after 7 days compared to placebo. This benefit was observed regardless of smoking status or concurrent antibiotic use . Another study found that oral albuterol was more effective than erythromycin (an antibiotic) in reducing cough after one week in adults with acute bronchitis, though it did not speed up return to work or normal activities .
Albuterol for Cough in Children with Upper Respiratory Infection
In children without asthma, studies consistently show that oral albuterol does not reduce the frequency or duration of cough due to upper respiratory infections. Randomized trials in non-asthmatic children found no difference in cough resolution between those treated with albuterol and those given placebo, but albuterol was associated with more side effects such as shaking or trembling Bernard1999Bernard2007. Similarly, in infants with mild-to-moderate viral bronchiolitis, oral albuterol did not shorten the illness or improve symptoms compared to placebo, and its widespread use in this group is not recommended .
Albuterol in Acute Bronchitis and Wheezing
For adults with acute bronchitis, albuterol (especially via inhaler) may help reduce cough duration, but the benefit is not universal and is not seen with oral albuterol in unselected patients with acute cough Littenberg1996Hueston1994Hueston1991. In children with episodic wheezing during respiratory infections, as-needed albuterol was less effective than tiotropium bromide in increasing symptom-free days, but it remains a standard option for symptom relief .
Summary of Albuterol’s Role in URI-Related Cough
- Adults: Albuterol inhalers may help reduce cough in acute bronchitis, but oral albuterol is not effective for general URI-related cough and causes more side effects Littenberg1996Hueston1994Hueston1991.
- Children: Oral albuterol does not help non-asthmatic children with acute cough from URIs and is not recommended due to lack of benefit and increased side effects Bernard1999Bernard2007Patel2003.
- Infants: No benefit from oral albuterol in mild-to-moderate bronchiolitis .
- Wheezing: Albuterol may be considered for children with wheezing, but other treatments like tiotropium may be more effective .
Conclusion
Albuterol is not effective for treating cough due to upper respiratory infection in most adults and children without underlying lung disease. Inhaled albuterol may help adults with acute bronchitis, but oral albuterol is not recommended for general URI-related cough due to lack of efficacy and increased side effects. In children and infants without asthma, albuterol does not reduce cough duration and should not be routinely used.
