The Food and Drug Administration (FDA) has not taken significant steps to ensure that antibiotic labels contain up-to-date breakpoints, according to a Government Accountability Office (GAO) report.
Breakpoints are the concentrations at which bacteria are susceptible to successful treatment with an antibiotic. At a time when antibiotic resistance is increasing, long-time established breakpoints may underestimate antibiotic dosage levels, leading to undertreatment of bacterial infections.
