For outpatient management, the Centers for Disease Control and Prevention recommends clindamycin 450 mg orally four times daily for 10-14 days, or doxycycline 100 mg orally twice daily plus metronidazole 500 mg orally twice daily for 10-14 days, with a moderate strength of evidence 2, 1

The Infectious Diseases Society of America suggests continuing parenteral therapy for at least 24 hours after clinical improvement, with a high strength of evidence 1
The American College of Obstetricians and Gynecologists recommends transitioning to oral therapy to complete a total of 14 days of treatment, with a moderate strength of evidence 1

The Centers for Disease Control and Prevention recommends monitoring patients closely for clinical improvement within 72 hours of initiating therapy, with a high strength of evidence 2
The Society for Healthcare Epidemiology of America suggests that those who don't respond to initial therapy within 72 hours may require adjustment of antibiotics or additional surgical intervention, with a moderate strength of evidence 2

The Infectious Diseases Society of America warns that inadequate anaerobic coverage can lead to treatment failure, with a high strength of evidence 1
