Treatment of Ureaplasma Infections
The recommended first-line treatment for Ureaplasma urealyticum infection is doxycycline 100 mg twice daily orally for 7 days, with azithromycin 1.0-1.5 g orally as a single dose being an effective alternative regimen. 1

Alternative Treatment:
- Azithromycin: 1.0-1.5 g orally as a single dose 1
Evidence Supporting Treatment Recommendations
The 2024 European Association of Urology (EAU) guidelines provide the most recent and authoritative recommendations for treating Ureaplasma infections. These guidelines specifically address Ureaplasma urealyticum treatment in their antimicrobial therapy regimens for urethritis 1.
Doxycycline is FDA-approved for treating "nongonococcal urethritis caused by Ureaplasma urealyticum" 2, which further supports its use as first-line therapy. The unique pharmacokinetic properties of doxycycline make it particularly effective against these organisms.
Efficacy of Treatment Options
Both treatment options have demonstrated similar efficacy in eradicating Ureaplasma infections:
A 2023 systematic review and meta-analysis found that azithromycin is effective in treating Ureaplasma urealyticum, with comparable efficacy to other control treatments (RR = 1.03,95% CI 0.94-1.12) 3.
Single-dose azithromycin (1g) has shown similar effectiveness to a 7-day regimen of doxycycline in treating Ureaplasma urealyticum infections 4.
Treatment Considerations and Caveats
When to Test and Treat
- Not all Ureaplasma detections warrant treatment. Asymptomatic carriage is common, and routine screening of asymptomatic individuals is not recommended 5.
Persistent Infection
Treatment failures can occur with both doxycycline and azithromycin. A study found persistent detection of Ureaplasma in 25-31% of cases after initial treatment with either medication 6.
For persistent non-gonococcal urethritis after first-line doxycycline, the EAU guidelines recommend:
- Azithromycin 500 mg orally on day 1, followed by 250 mg for 4 days
- If macrolide resistance is suspected, moxifloxacin 400 mg daily for 7-14 days 1
Partner Management
- Sexual partners from the preceding 60 days should be referred for evaluation and treatment to prevent reinfection 1.
Treatment Adherence
- Single-dose regimens (azithromycin) offer the advantage of improved compliance and directly observed therapy 1.
- If using multi-dose regimens (doxycycline), medication should ideally be provided in the clinic or healthcare provider's office to improve adherence 1.
Follow-up Recommendations
- Patients should be instructed to return for evaluation if symptoms persist or recur after completing therapy 1.
- Symptoms alone, without documentation of signs or laboratory evidence of inflammation, are not sufficient basis for retreatment 1.
- Patients should abstain from sexual intercourse until 7 days after therapy is initiated 1.
By following these evidence-based treatment recommendations, clinicians can effectively manage Ureaplasma infections while minimizing the risk of treatment failure and antimicrobial resistance.
