Cellulitis is an infection of the dermis and subcutaneous tissue.The most common
causative organisms are Streptococcus or Staphylococcus spp. but they can be caused
by a wide range of both aerobic and anaerobic bacteria.

Flucloxacillin in adults is usually given as first-line in uncomplicated infection. In
sufficient doses, this covers both beta-haemolytic streptococci and penicillinaseresistant
staphylococci.

Erythromycin or Clindamycin can be used if the patient is penicillin-allergic.
