Antibiotic Class Profile

All Antibiotic Classes

Antibiotics work in different ways to kill bacteria or stop them from growing. "All classes" of antibiotics groups together all types of antibiotic types. In this portal, antibiotics are classified into one of the following classes: penicillins, fluoroquinolones, cephalosporins, macrolides, beta-lactams with increased activity (e.g. amoxicillin-clavulanate), tetracyclines, trimethoprim-sulfamethoxazole, lincosamides (e.g. clindamycin), urinary anti-infectives, and other antibiotics. For more information about antibiotic classes and example agents that fall into each antibiotic class, explore Antibiotic Class Definitions.


  • These data are from the IQVIA database and reflect all outpatient antibiotic prescriptions dispensed to humans from U.S. community pharmacies. These data do not include antibiotic prescriptions dispensed from federal facilities.
  • Data reflect annual rates of antibiotic prescriptions dispensed per 1,000 population, i.e. the number of antibiotic prescriptions dispensed per year for every 1,000 persons. Annual rates allow for comparisons of the number of antibiotic prescriptions dispensed in different geographic areas or over time while controlling for differences in the size of the underlying population.
  • Map legends are classified using the Jenks Natural Breaks method.
  • Due to missing data, totals by age group and/or sex may not add up to all prescriptions. Antibiotic class defines a set of related antibiotics. State-level rates of penicillins, macrolides, cephalosporins, and fluoroquinolones are displayed. Also displayed are all antibiotic classes, which include these four classes plus additional classes not available for release at the state level.
  • Data are not available for geographic regions smaller than states.
