New research suggests a pattern of outpatient antibiotic overuse in parts of the United States-- particularly in the Southeast --a problem that could accelerate the rate at which these powerful drugs are rendered useless, according to Extending the Cure, a project of the Center for Disease Dynamics, Economics & Policy.
- The five states with the highest antibiotic use in the nation are West Virginia, Kentucky, Tennessee, Louisiana and Alabama. However, the maps show higher than average use of antibiotics in other regions of the country as well. Check your state's antibiotics use at ResistanceMap.
- Prescribing rates for a powerful class of antibiotics known as fluoroquinolones shot up by 49 percent from 1999 to 2007. At the same time, antibiotic resistance is increasing: these drugs are now seven times less likely to work against Escherichia coli, the most frequent cause of bacterial infections, than they were in 1999.
- Penicillins remain the most popular antibiotics -- accounting for nearly one out of three prescriptions filled in the United States. At the same time, the market share of these standard drugs has declined by 28 percent as physicians increasingly turn to more powerful antibiotics.
