First seen Nov 01, 2025 · Last updated May 16, 2026 · Updated 34 times

Summary

This study tested whether taking doxycycline for 3 days works as well as the standard 7-day course to cure chlamydia. About 664 men and women with chlamydia took either a 3-day or 7-day regimen, and were tested again after 28 days. The goal is to see if a shorter treatment can be just as effective, making it easier for patients to complete.
