Description

Introduction

Azithromycin is a widely used antibiotic belonging to the macrolide class. It works by stopping bacteria from growing and multiplying. Azithromycin is commonly prescribed because of its broad-spectrum activity, once-daily dosing, and short treatment duration. It is important to note that Azithromycin treats bacterial infections, not viral infections like the flu or common cold.

Azithromycin is prescribed when a bacterial infection is confirmed or strongly suspected. Doctors recommend it because it:
