Treatment of Abdominal Wall Cellulitis

Initial Antibiotic Selection

• The American College of Physicians recommends beta-lactam monotherapy for uncomplicated abdominal wall cellulitis without purulent drainage or MRSA risk factors, with a success rate of 96% in typical cellulitis cases 1

Intravenous Options for Hospitalized Patients

• The Infectious Diseases Society of America recommends cefazolin 1-2 g IV every 8 hours as a preferred IV beta-lactam for hospitalized patients with abdominal wall cellulitis 2, 1

Treatment Duration

• The American College of Physicians recommends treating abdominal wall cellulitis for exactly 5 days if clinical improvement has occurred, with high-quality randomized controlled trial evidence demonstrating 98% clinical resolution with no relapse by 28 days 1

Severe Infections Requiring Broad-Spectrum Therapy

• The Infectious Diseases Society of America recommends vancomycin 15-20 mg/kg IV every 8-12 hours PLUS piperacillin-tazobactam 3.375 g IV every 6 hours for abdominal wall cellulitis with signs of systemic toxicity, rapid progression, or suspected necrotizing fasciitis 2, 1

Adjunctive Measures

• Elevation of the affected area promotes gravitational drainage of edema and inflammatory substances, hastening improvement, as recommended by the American College of Physicians 1, 3
