Antibiotic prophylaxis for intrauterine contraceptive device insertion

Area of Science:

• Reproductive Health
• Infectious Disease Prevention
• Contraception

Background:

• Intrauterine devices (IUDs) are effective contraceptives, but fear of pelvic inflammatory disease (PID) limits their use.
• IUD-related infections primarily occur shortly after insertion, suggesting bacterial contamination during the procedure.
• Prophylactic antibiotics may reduce the risk of upper genital tract infections associated with IUD insertion.

Purpose of the Study:

• To evaluate the efficacy of prophylactic antibiotics administered before IUD insertion.
• To assess the impact on IUD-related complications, including PID and early device removal within three months.
• To analyze the effect on unscheduled provider visits.

Main Methods:

• Conducted a systematic review of randomized controlled trials (RCTs) comparing prophylactic antibiotics with placebo.
• Searched major databases (MEDLINE, EMBASE, CENTRAL) and contacted experts for relevant studies.
• Analyzed data using the Peto modified Mantel-Haenszel technique to calculate odds ratios.

Main Results:

• Prophylactic doxycycline or azithromycin showed no significant reduction in pelvic inflammatory disease (OR 0.89; 95% CI 0.53-1.51).
• A small, marginally significant reduction in unscheduled provider visits was observed (OR 0.82; 95% CI 0.70-0.98).
• Antibiotic prophylaxis had minimal impact on IUD removal rates within 90 days (OR 1.05; 95% CI 0.68-1.63).

Conclusions:

• Pre-insertion antibiotic prophylaxis with doxycycline or azithromycin provides little benefit in preventing IUD-related infections.
• The cost-effectiveness of routine antibiotic prophylaxis is questionable, despite a minor reduction in unscheduled visits.
• Overall, the risk of IUD-associated infection is low, irrespective of antibiotic prophylaxis.
