First seen Aug 05, 2026 · Last updated Aug 06, 2026 · Updated 1 time

Summary

This trial tests two approved antibiotics—azithromycin (a single dose) and doxycycline (twice daily for a week)—to see which is more effective at curing genital chlamydia in young people aged 12-21 living in youth correctional facilities. Participants provide urine samples over about two months to check if the infection clears. The goal is to find the best treatment to prevent reinfection and serious health issues.
