Response: This review is an update of the 2010 Cochrane Review of Interventions for cellulitis and erysipelas (DOI: 10.1002/14651858.CD004299) but focusing on antibiotics.  It provides a valuable resource for clinicians in summarizing current best evidence and highlighting gaps in the research. This review will inform the production of evidence-based guidelines covering antibiotic choice, route of administration, duration of treatment and the role of combinations of antibiotics.

Study Finds Single Antibiotic Cephalexin Alone Is Appropriate Outpatient Treatment For Cellulitis Interview with:

Response: The bacterial etiology of cellulitis is difficult to determine because there is usually no material for culture, but streptococci are believed to be the most common etiology. Since the emergence of MRSA as a common cause of skin infections in the community, many clinicians add a second antibiotic with MRSA activity to an oral cephalosporin, such as a combination of cephalexin plus trimethoprim-sulfamethoxazole. It is unknown if there is an additional benefit to adding MRSA activity for treatment of cellulitis. This randomized, blinded trial compared cephalexin plus placebo to cephalexin plus trimethoprim-sulfamethoxazole for outpatient treatment of cellulitis without an abscess or wound.

Bottom line: We did not find a benefit from addition of trimethoprim-sulfamethoxazole.
