how long does it take for doxycycline to work for ureaplasma?
A study by Khosropour et al. noted that 57% of individuals with NGU who were infected with Ureaplasma spp. and received antimicrobial therapy with initially azithromycin (1 g) followed by doxycycline (100 mg twice daily for 7 days), or vice versa, were still colonized after 6 weeks of therapy.
