Can vancomycin be used for MRSA?

What is the best treatment for MRSA?

Empiric therapy for MRSA is recommended, pending sputum and/or blood culture results, for hospitalized patients with severe community-acquired pneumonia defined by one of the following: a requirement for admission to the intensive care unit, necrotizing or cavitary infiltrates, or empyema. Treatment options for health care–associated MRSA or community-associated MRSA pneumonia include seven to 21 days of intravenous vancomycin or linezolid, or clindamycin (600 mg orally or intravenously three times per day) if the strain is susceptible. In patients with MRSA pneumonia complicated by empyema, antimicrobial therapy should be used with drainage procedures.

What is the minimum inhibitory concentration of vancomycin?

For isolates with a vancomycin minimal inhibitory concentration of 2 mcg per mL or less (e.g., susceptible according to Clinical and Laboratory Standards Institute breakpoints), the patient's clinical response should dictate the continued use of vancomycin, independent of the minimal inhibitory concentration. If the patient has had a previous clinical and microbiologic response to vancomycin, it may be continued with close follow-up. If the patient has not responded to vancomycin therapy despite adequate debridement and removal of other foci of infection, an alternative agent is recommended. For isolates with a vancomycin minimal inhibitory concentration greater than 2 mcg per mL (e.g., vancomycin-intermediate S. aureus, vancomycin-resistant S. aureus ), an alternative agent should be prescribed.

Some experts suggest an additional one to three months (and possibly longer for chronic infection or if debridement is not performed) of oral rifampin-based combination therapy with TMP/SMX, doxycycline, minocycline, clindamycin, or a fluoroquinolone, chosen based on susceptibilities.
