Salpingo‑oophoritis Antibiotic Regimen (Pelvic Inflammatory Disease)
Empiric broad-spectrum antibiotics should be started promptly for suspected salpingo‑oophoritis based on clinical diagnosis because long-term sequelae are dependent on early treatment. [1]
Recommended regimens should cover N. gonorrhoeae, C. trachomatis, and anaerobes. [1]
Antibiotic Coverage Approach
Empiric therapy should provide coverage for:
- N. gonorrhoeae and C. trachomatis. [1]
- Anaerobic bacteria. [1]
Empiric use of metronidazole is recommended to improve eradication of anaerobic organisms when included in the PID regimen. [1]
Hospitalization Indications (Including Suspected/Confirmed Tubo‑Ovarian Abscess)
Hospitalization and parenteral therapy are recommended when any of the following are present:
- Tubo‑ovarian abscess. [1]
- Pregnancy. [1]
- Severe illness (including nausea and vomiting) or temperature >38.5°C (101°F). [1]
- Inability to tolerate or adhere to an outpatient oral regimen. [1]
- No clinical response to oral antimicrobial therapy. [1]
For tubo‑ovarian abscess, >24 hours of inpatient observation is recommended. [1]
Recommended Parenteral Regimen (Inpatient PID)
For inpatient salpingo‑oophoritis/PID (without specifying an alternative for drug allergy), recommended parenteral therapy is one of the following regimens. [1]
Regimen A
- Ceftriaxone 1 g IV every 24 hours plus doxycycline 100 mg orally or IV every 12 hours plus metronidazole 500 mg orally or IV every 12 hours. [1]
Regimen B
- Cefotetan 2 g IV every 12 hours plus doxycycline 100 mg orally or IV every 12 hours. [1]
Regimen C
- Cefoxitin 2 g IV every 6 hours plus doxycycline 100 mg orally or IV every 12 hours. [1]
Transition to oral therapy is recommended after clinical improvement with parenteral therapy. [1]
Transition to Oral Therapy and Total Duration
After clinical improvement with parenteral therapy, transition to oral therapy with:
- Doxycycline 100 mg twice daily plus metronidazole 500 mg twice daily to complete a total 14 days of antimicrobial therapy. [1]
Alternative Parenteral Regimens (Tubo‑Ovarian Abscess or Other Indications)
Alternative parenteral regimens for PID include the following. [1]
- Ampicillin‑sulbactam plus doxycycline: ampicillin‑sulbactam 3 g IV every 6 hours plus doxycycline 100 mg orally or IV every 12 hours. [1]
- Clindamycin plus gentamicin: clindamycin 900 mg IV every 8 hours plus gentamicin loading dose 2 mg/kg IV or IM, followed by 1.5 mg/kg every 8 hours (single daily dosing 3–5 mg/kg can be substituted). [1]
When tubo‑ovarian abscess is present, completion of therapy is recommended as:
- Clindamycin 450 mg orally 4 times/day or metronidazole 500 mg orally twice/day to complete 14 days, with oral doxycycline also used for anaerobic coverage strategy. [1]
Recommended Intramuscular or Oral Regimen (When Mild-to-Moderate and Outpatient Management Appropriate)
Intramuscular or oral therapy can be considered for women with mild-to-moderate acute PID when outpatient management is appropriate. [1]
Recommended IM/oral regimens are one of the following. [1]
- Ceftriaxone 500 mg IM in a single dose plus doxycycline 100 mg orally twice/day for 14 days with metronidazole 500 mg orally twice/day for 14 days. [1]
- Cefoxitin 2 g IM in a single dose plus probenecid 1 g orally in a single dose plus doxycycline 100 mg orally twice/day for 14 days with metronidazole 500 mg orally twice/day for 14 days. [1]
- Other parenteral third‑generation cephalosporin (e.g., ceftizoxime or cefotaxime) plus doxycycline 100 mg orally twice/day for 14 days with metronidazole 500 mg orally twice/day for 14 days. [1]
Clinical Reassessment Threshold
Clinical improvement should occur within <3 days of therapy initiation. [1]
If no clinical improvement occurs within <72 hours after outpatient IM or oral therapy, hospitalization, reassessment of the antimicrobial regimen, and additional diagnostics are recommended. [1]
