The safety of azithromycin in the treatment of adults with community-acquired respiratory tract infections.

The comparative safety of azithromycin was assessed in adult patients (> or =12 years) with community-acquired respiratory tract infections. Of 3229 patients evaluated, 1616 received azithromycin 500 mg once daily for 3 days and 1613 received standard regimens of amoxycillin, amoxycillin/clavulanic acid, cefaclor, clarithromycin, or roxithromycin. A similar incidence of treatment-related adverse events occurred with azithromycin (10.3%) and comparators (11.5%). Significantly fewer patients were withdrawn from azithromycin than comparator treatment (0.4 versus 2.1%; P=0.0001). Most adverse events were mild/moderate in intensity and affected the gastrointestinal system. Azithromycin was as well tolerated as other antibiotics commonly used for bacterial infections in adults.
