Taking a 5 day dose of Azithromycin. All I can say is I hope it works.
As much as antibiotics are unfortunately over-prescribed or prescribed when they are not indicated - bronchitis is something that does demand antibiotics. If you get it in the future ask your doctor for one called Zithromax in the 5 day dosage package. You take two the first day then one each following day for three days.
While you're right on about antibiotics being over utilized, you are dead wrong about bronchitis being something that demands antibiotics. Acute bronchitis is overwhelmingly of viral etiology and requires only reassurance and supportive therapy for treatment. Bacterial causes of acute bronchitis account for between 2-10% of cases. As such, the vast majority of cases of acute bronchitis do not benefit in any way from antibiotic therapy.
