Overview

Azithromycin, often known by the brand name Zithromax or as part of a Z-Pak, is an antibiotic medication belonging to the macrolide class. It works by stopping the growth of bacteria and is prescribed to treat a variety of bacterial infections. These include respiratory tract infections such as pneumonia and bronchitis, certain ear infections, skin infections, and some sexually transmitted infections like chlamydia. Azithromycin is not effective against viral infections, such as the common cold or flu. Its prolonged half-life allows for once-daily dosing and shorter treatment courses compared to some other antibiotics. (Source: MedlinePlus, DrugBank)
