WEDNESDAY, Nov. 16 (HealthDay News) -- Overall outpatient use of
antibiotics in the United States fell about 12 percent between 1999
and 2007, but alarmingly high use in the Southeast could speed the
development of antibiotic-resistant bacteria, researchers warn.
The findings were released by Extending the Cure, a project of
the Center for Disease Dynamics, Economics & Policy in
The five states with the highest antibiotic use are West
Virginia, Kentucky, Tennessee, Louisiana and Alabama. Residents of
West Virginia and Kentucky take about twice as many antibiotics per
capita as those living in Oregon and Alaska.
Penicillins are the most popular antibiotics and account for
nearly one out of every three prescriptions filled in the United
States. But the market share of penicillins has fallen 28 percent
as doctors increasingly turn to more powerful antibiotics,
according to a news release from Extending the Cure.
Between 1999 and 2007, prescribing rates for a powerful class of
antibiotics called fluoroquinolones rose 49 percent. But with
increasing antibiotic resistance, these drugs are now seven times
less likely to work against E. coli than they were in 1999.
The release of the findings coincides with this week's U.S.
Centers for Disease Control and Prevention's annual campaign to
reduce antibiotic overuse.
