Tailor antibiotics by regional antibiogram[1]

Outpatient

Coverage primarily for Strep

MRSA coverage only necessary if cellulitis associated with: purulence, penetrating trauma, known MRSA colonization, IV drug use, or SIRS[2]

  • 5 day treatment duration, unless symptoms do not improve within that timeframe[2]
    • Cephalexin 500mg PO q6hrs OR
      • Add TMP/SMX DS 1 tab PO BID[3] if MRSA is suspected
      • Most cases of non-purulent cellulitis are caused by Strep. In these cases, the addition of TMP/SMX has been demonstrated to offer no clinical benefit over cephalexin alone.[4]
    • Clindamycin 450mg PO TID covers both Strep and Staph
    • Tetracyclines (like Doxycycline) should be avoided in non-purulent cellulitis due to high rates of Strep resistance[5]


Inpatient


Saltwater related cellulitis

coverage extended for Vibrio vulnificus


Freshwater related cellulitis

coverage extended for Aeromonas sp
