In these situations, greater levels of caution are required Recognition of synergism between penicillin-streptomycin led to an improvement in cure rates for enterococcal endocarditis, from approximately 40% to greater than 80% (Jensen, Frimodt-Møller, & Aarestrup, 1999; Rice & Carias, 1998)..

The label of “penicillin allergy” is not an absolute contraindication to using piperacillin-tazobactam or nafcillin Nevertheless, recent studies have shown that the rate of cross-reactivity of imipenem and meropenem with penicillins is lower than 1%. Approach to patient with a beta-lactam allergy. ” Figure: Penicillin Core Structure Selected References: 1..
