Azithromycin, commonly known by its brand name Zithromax, is a widely used antibiotic that belongs to the macrolide class. It is effective against a broad spectrum of bacterial infections, making it a versatile treatment option for various medical conditions. Azithromycin works by inhibiting the growth of bacteria, thereby helping the body's immune system to fight off the infection. In this article, we will explore the uses of azithromycin, what it treats effectively, and its role in managing different bacterial infections.
