Treatment Regimen for Endometritis

Diagnostic Criteria

The Centers for Disease Control and Prevention recommends confirming the diagnosis of endometritis based on minimum criteria: lower abdominal tenderness, adnexal tenderness, and cervical motion tenderness 3, 4, 5
Supporting criteria for endometritis diagnosis include oral temperature >38.3°C (>101°F), abnormal cervical or vaginal discharge, elevated erythrocyte sedimentation rate or C-reactive protein, and laboratory documentation of cervical infection with N. gonorrhoeae or C. trachomatis 6, 5

The Centers for Disease Control and Prevention recommends a first-line regimen of clindamycin 900 mg IV every 8 hours plus gentamicin loading dose IV or IM (2 mg/kg) followed by maintenance dose (1.5 mg/kg) every 8 hours for at least 48 hours after clinical improvement, followed by oral doxycycline 100 mg twice daily to complete 10-14 days of total therapy 1, 2
An alternative regimen is cefoxitin 2 g IV every 6 hours or cefotetan 2 g IV every 12 hours plus doxycycline 100 mg orally or IV every 12 hours, continued for at least 48 hours after clinical improvement, and then oral doxycycline 100 mg twice daily for a total of 10-14 days 1, 2

Hospitalization for parenteral therapy is recommended when surgical emergencies such as appendicitis or ectopic pregnancy cannot be excluded, the patient is pregnant, a pelvic abscess is suspected, the patient is an adolescent, severe illness or nausea and vomiting precludes outpatient management, the patient is unable to follow or tolerate an outpatient regimen, or the patient has failed to respond to outpatient therapy 6, 7, 1, 2
Clinical follow-up within 72 hours cannot be arranged, hospitalization is also recommended 1, 2

The Centers for Disease Control and Prevention recommends continuing IV antibiotics for at least 48 hours after clinical improvement, and then completing a total of 10-14 days of therapy with oral doxycycline 1, 2

Clindamycin has more complete anaerobic coverage than doxycycline, which is important when treating endometritis 1, 2
When C. trachomatis is strongly suspected, ensure doxycycline is included in the regimen 1, 2

Discontinuing IV therapy too early before clinical improvement is established 1, 2
Not screening for and treating sexually transmitted infections that may be the underlying cause 6, 5
