What is the treatment for Pelvic Inflammatory Disease (PID)?

From the Guidelines

Pelvic inflammatory disease (PID) requires prompt antibiotic treatment to prevent complications, and the recommended treatment is a combination of antibiotics that cover a broad spectrum of bacteria, as outlined in the 2002 guidelines by the Centers for Disease Control and Prevention 1, 2, 3.

Treatment Regimens

The standard regimen for outpatient treatment includes:

• Ceftriaxone 250mg as a single intramuscular injection
• Doxycycline 100mg orally twice daily for 14 days
• Metronidazole 500mg orally twice daily for 14 days may be added to provide better anaerobic coverage For more severe cases requiring hospitalization, intravenous antibiotics are used, typically including:
• Cefotetan 2g IV every 12 hours or cefoxitin 2g IV every 6 hours
• Doxycycline 100mg orally or IV every 12 hours ### Duration of Treatment Treatment should continue for at least 24-48 hours after clinical improvement, followed by oral therapy to complete 14 days, as recommended by the guidelines 3.

Additional Considerations

• Sexual partners from the past 60 days should also be treated to prevent reinfection
• Patients should abstain from sexual intercourse until treatment is complete and symptoms have resolved
• Follow-up within 72 hours is important to ensure improvement
• PID treatment is crucial as untreated infections can lead to chronic pelvic pain, infertility, and ectopic pregnancy due to scarring of the reproductive organs, highlighting the importance of prompt and effective treatment, as noted in the guidelines 1, 2.

From the FDA Drug Label

Pelvic Inflammatory Disease caused by Neisseria gonorrhoeae Ceftriaxone sodium, like other cephalosporins, has no activity against Chlamydia trachomatis. Therefore, when cephalosporins are used in the treatment of patients with pelvic inflammatory disease and Chlamydia trachomatis is one of the suspected pathogens, appropriate antichlamydial coverage should be added

• The treatment for Pelvic Inflammatory Disease (PID) includes ceftriaxone for infections caused by Neisseria gonorrhoeae.
• However, since Chlamydia trachomatis is also a common cause of PID and ceftriaxone has no activity against it, appropriate antichlamydial coverage should be added.
• Alternatively, cefoxitin can be used to treat PID caused by Escherichia coli, Neisseria gonorrhoeae, Bacteroides species, Clostridium species, and other susceptible organisms [4] [5].

From the Research

Treatment Overview

The treatment for Pelvic Inflammatory Disease (PID) typically involves the use of broad-spectrum antibiotics to cover a range of pathogens, including Neisseria gonorrhoeae, Chlamydia trachomatis, and anaerobic bacteria 6, 7, 8, 9, 10. The goals of therapy include resolving clinical symptoms and signs, eradicating pathogens from the genital tract, and preventing long-term sequelae such as infertility, ectopic pregnancy, and chronic pelvic pain 6.

Antibiotic Regimens

• For mild-to-moderate PID, outpatient treatment with tolerated antibiotic regimens consisting of an extended-spectrum cephalosporin in conjunction with either azithromycin or doxycycline is recommended 6.
• For clinically severe PID, hospitalization and parenteral broad-spectrum antibiotic therapy with activity against a polymicrobial flora, particularly Gram-negative aerobes and anaerobes, should be implemented 6.
• Azithromycin versus doxycycline: there is no clear evidence of a difference between the two drugs in rates of cure for mild-moderate PID, but azithromycin may be more effective than doxycycline in achieving cure in mild-moderate PID in a sensitivity analysis limited to a single study at low risk of bias 8, 9.
• Quinolone versus cephalosporin: there is no clear evidence of a difference between the two drugs in rates of cure for mild-moderate PID or severe PID 8, 9.
• Nitroimidazole versus no use of nitroimidazole: there is no conclusive evidence of a difference between the nitroimidazoles (metronidazole) group and the group receiving other drugs with activity over anaerobes in rates of cure for mild-moderate PID or severe PID 8, 9.

Importance of Early Treatment

Early administration of antibiotics is necessary to reduce the risk of long-term sequelae, and the suspicion of PID should be confirmed by genital assessment for signs of inflammation or infection, blood test, and imaging evaluation 10. Laparoscopic approach is considered the gold standard for diagnosis 10.
