Which treatment option is least appropriate for a patient with acute bronchitis?

In the context of acute bronchitis, the most appropriate treatment options focus on symptom relief rather than the use of antibiotics. Acute bronchitis is typically viral in origin, and antibiotics are effective only against bacterial infections. As a result, their use in acute bronchitis does not alter the course of the illness and can lead to unnecessary side effects and antibiotic resistance.

Expectorants can help loosen mucus and make coughing more productive, while bronchodilators may provide relief for symptoms such as wheezing or shortness of breath, particularly in patients with underlying conditions like asthma or COPD. Antitussives can reduce the frequency of coughing, especially when the cough is dry and disruptive. Each of these interventions supports the management of symptoms associated with acute bronchitis.

In summary, avoiding antibiotics in acute bronchitis is essential since the condition is primarily viral, and using antibiotics in this scenario is considered least appropriate.
