What is the recommended treatment for Ureaplasma infections?

Treatment of Ureaplasma Infections

Doxycycline 100 mg orally twice daily for 7 days is the recommended first-line treatment for Ureaplasma infections. 1

First-Line Treatment Options

• Doxycycline: 100 mg orally twice daily for 7 days

  • FDA-approved specifically for nongonococcal urethritis caused by Ureaplasma urealyticum 2
  • Recommended by the American College of Obstetricians and Gynecologists as first-line therapy 1

• Azithromycin: Alternative first-line option

  • Dosing: 1.0-1.5 g orally as a single dose 1
  • Offers advantage of single-dose administration, which may improve compliance 3, 4
  • Studies have shown similar effectiveness to 7-day doxycycline regimens 3

Second-Line Treatment Options

If symptoms persist after initial treatment:

• After doxycycline failure: Switch to azithromycin 500 mg on day 1, then 250 mg daily for 4 days 1

• After azithromycin failure: Switch to moxifloxacin 400 mg daily for 7-14 days 1

  • Particularly useful in cases with suspected macrolide resistance

Special Populations

Pregnant Women

• Erythromycin is the preferred treatment during pregnancy 1
  • Erythromycin base: 500 mg orally four times daily for 7 days, OR
  • Erythromycin ethylsuccinate: 800 mg orally four times daily for 7 days

Treatment Challenges

• Antimicrobial resistance: Resistance to macrolides, tetracyclines, and fluoroquinolones has been reported 1, 5

  • Consider local resistance patterns when selecting therapy
  • In a 2015 study, persistent detection of Ureaplasma was common even after sequential treatment with doxycycline, azithromycin, and moxifloxacin 6

• Partner treatment: Concurrent treatment of sexual partners is essential to prevent reinfection 1

Important Clinical Considerations

• Diagnostic approach: Testing is recommended primarily for:

  • Persistent or recurrent urethritis
  • Non-gonococcal urethritis where other causes have been ruled out
  • Before urological procedures that will breach the mucosa 1

• Avoid unnecessary testing: Routine screening for asymptomatic individuals is not recommended due to high colonization rates 1, 7

• Post-treatment recommendations:

  • Abstain from sexual intercourse until 7 days after initiating therapy or resolution of symptoms 1
  • Follow-up is recommended if symptoms persist or recur after treatment 1

• Administration guidance: Take doxycycline with adequate fluids and with food or milk if gastric irritation occurs 2
