MRSA treatment guidelines issued

The IDSA has issued MRSA treatment guidelines. Although the full document is lengthy, here are some of the highlights: Vancomycin is still first line treatment for most patients with invasive MRSA infections. Second line agents include linezolid, daptomycin (but not in pneumonia), and clindamycin. For CA-MRSA skin / soft tissue infections, those with an abscess should be drained (and do not necessarily need antibiotics) while those with purulent cellulitis should be treated with a CA-MRSA agent (TMP-SMX, clindamycin, tetracycline, linezolid). Vancomycin dosing should be 15-20mg/kg for most patients, with trough level goals of 15-20. For patients with an MIC>2, close clinical follow up is recommended, with switching to another agent for treatment failure (Full guidelines).
