Comparison with Other Treatments

Azithromycin is a macrolide antibiotic used for selected bacterial infections. Other antibiotic classes, including penicillins, cephalosporins, tetracyclines, and fluoroquinolones, may be used for different clinical indications. Selection depends on the suspected or confirmed organism, bacterial susceptibility, infection site, allergy history, patient factors, and applicable treatment guidance. The choice of antibiotic should therefore be individualized to the clinical situation.
