Treatment
Antibiotics
In most cases, acute bronchitis is caused by viruses, not bacteria and it will go away on its own without antibiotics. To treat acute bronchitis that appears to be caused by a bacterial infection, or as a precaution, antibiotics may be given.[1]
If antibiotics are used, a meta-analysis found that "amoxicillin/clavulanic acid, macrolides, second-generation or third-generation cephalosporins, and quinolones" may be more effective.[2]
Smoking cessation
To help the bronchial tree heal faster and not make bronchitis worse, smokers should completely quit smoking. [3]
Prognosis
Acute bronchitis usually lasts approximately 20 or 30 days. It may accompany or closely follow a cold or the flu, or may occur on its own. Bronchitis usually begins with a dry cough, including waking the sufferer at night. After a few days it progresses to a wetter or productive cough, which may be accompanied by fever, fatigue, and headache. The fever, fatigue, and malaise may last only a few days; but the wet cough may last up to several weeks.
Should the cough last longer than a month, some doctors may issue a referral to an otolaryngologist (ear, nose and throat doctor) to see if a condition other than bronchitis is causing the irritation. It is possible that having irritated bronchial tubes for as long as a few months may inspire asthmatic conditions in some patients.
In addition, if one starts coughing mucus tinged with blood, one should see a doctor. In rare cases, doctors may conduct tests to see if the cause is a serious condition such as tuberculosis or lung cancer.
Prevention
In 1985, University of Newcastle, Australia Professor Robert Clancy developed an oral vaccine for acute bronchitis. This vaccine was commercialised four years later as Broncostat.[2]
