Azithromycin works by stopping the growth of bacteria. It does this by interfering with their ability to make proteins, which are essential for their survival.

Scientifically, Azithromycin binds to the 50S ribosomal subunit of the bacterial ribosome, inhibiting the translocation steps in protein synthesis. This action prevents the bacteria from growing and multiplying, allowing the body's immune system to eliminate the infection.

• Broad Spectrum — Effective against a wide range of bacteria.
• Convenient Dosing — Typically requires once-daily dosing.
• Well-Tolerated — Generally has fewer side effects compared to other antibiotics.

Initial improvement in symptoms can be seen within a few days of starting the medication. The full course of treatment usually lasts 3 to 5 days. If there is no improvement in symptoms after completing the course, consult your doctor.
