A member asked:

How quickly does azithromycin begin to work on bronchitis?

A doctor has provided 1 answer

Bronchitis: Bronchitis, if acute, is rarely caused by bacteria. It is 9+% viral, some toxic inhalants and a few bacterial like adult whooping cough (Pertussis). If this is treatment of exacerbation of chronic bronchitis, azithromycin, if it is going to be effective should begin to have efficacy within 24 hours.
