What is the treatment of chlamydial lower genitourinary tract infection?
Chlamydial lower genitourinary tract infection is a sexually transmitted infection caused by C. trachomatis. A first-line antibiotic protocol exists with specific agent selection and defined microbiological endpoints to confirm cure.
Treatment goals
Success is measured by a negative C. trachomatis nucleic acid amplification test at 4–6 weeks after completing therapy, along with resolution of urogenital symptoms.
Treatment approach
The protocol recommends a specific antibiotic — doxycycline as the preferred first-line agent — with a defined preference over alternative antibiotic options based on comparative effectiveness evidence. Full agent selection, dosing details, monitoring schedule, and partner management guidance are in the complete protocol.

- Recommendation to treat all C. trachomatis infections with doxycycline as first line in preference to single-dose azithromycin regimens.
- Treatment regimens with azithromycin are less effective than doxycycline for urogenital C. trachomatis infections in men, and for pharyngeal and especially rectal C. trachomatis infections in both sexes.

- When TOC is indicated, C. trachomatis NAATs should be performed at least 4 weeks after completion of therapy.
- Patients with a positive C. trachomatis test should be advised to abstain from sexual contact for 7 days after they and their sexual partners have completed treatment and any symptoms have resolved.
