The MIC corresponding to daptomycin susceptibility for vancomycin-resistant enterococci (VRE) is ≤ 4 mg/L. Based on the concentration-dependent killing properties of daptomycin, there may be concern about achieving adequate concentrations when the MIC approaches the upper end of the susceptible range (3-4 mg/L). Higher doses of daptomycin may be needed to treat VRE isolates with higher MICs.
