I now have comprehensive information to write a thorough answer. Let me compile it.

Leukorrhea - Causes and Treatment

Leukorrhea (leucorrhoea) refers to white or whitish vaginal discharge. It is a symptom, not a disease - and the approach to treatment depends entirely on identifying the underlying cause.

Step 1: Classify the Discharge

Before any treatment, clinical evaluation is key:
FeatureSuggests
Greenish, frothy, malodorousTrichomoniasis
Curdy/white, itchyVulvovaginal Candidiasis (VVC)
Thin, gray-white, fishy odorBacterial Vaginosis (BV)
Mucopurulent from cervixCervicitis (Gonorrhea/Chlamydia)
Clear/white, no itch, no odorPhysiological leukorrhea
Vaginal pH (using pH paper) helps: pH >4.5 suggests BV or Trichomoniasis; normal pH (<4.5) with pruritus suggests candidiasis.

Physiological Leukorrhea

Physiological discharge is thin, slippery, and clear or white - seen in neonates (first 2-3 weeks of life), at ovulation, during pregnancy, and with hormonal contraceptives. No treatment is required. Reassurance and hygiene counseling are sufficient.

Specific Treatments by Etiology

1. Bacterial Vaginosis (BV)

Most common cause - up to 50% of vaginal discharge cases
Oral therapy (first-line):
  • Metronidazole 500 mg orally, twice daily for 7 days (preferred over single dose)
  • Tinidazole 1 g daily for 5 days, OR 2 g daily for 3 days
  • Clindamycin 300 mg orally twice daily for 7 days
  • Secnidazole 2 g orally, single dose (also effective)
Intravaginal therapy:
  • Metronidazole 0.75% gel - 5 g (one applicator) intravaginally twice daily for 5 days
  • Clindamycin 2% cream - 5 g intravaginally once nightly for 7 nights
  • Clindamycin ovules 100 mg intravaginally once at bedtime for 3 days
Note: Treatment of male partners does NOT reduce recurrence of BV. Recurrence is common.
  • Harrison's Principles of Internal Medicine 22E, p. 1146

2. Trichomoniasis (Trichomonas vaginalis)

Profuse, yellow-green, frothy discharge; strawberry cervix; pH >5
Treatment:
  • Metronidazole 500 mg orally twice daily for 7 days (preferred - more effective than single dose)
  • Tinidazole (longer half-life, fewer GI side effects) - useful for metronidazole-resistant cases
  • Single 2-g oral dose of metronidazole is a historical standard but is less effective than the 7-day course
Key point: Treat sexual partners - this is standard of care and significantly reduces reinfection. Intravaginal metronidazole gel is not reliable for trichomoniasis; systemic treatment is required.
  • Harrison's Principles of Internal Medicine 22E, p. 1145

3. Vulvovaginal Candidiasis (VVC)

White curdy discharge, intense pruritus, normal or slightly low pH
Uncomplicated (first episode or infrequent):
  • Fluconazole 150 mg orally, single dose (preferred by many patients)
  • Clotrimazole 2 x 100 mg vaginal tablets daily for 3 days
  • Miconazole 1200 mg vaginal suppository, single dose
  • Any intravaginal imidazole for 3-7 days (miconazole, clotrimazole cream)
Complicated/Recurrent VVC:
  • Prolonged or periodic oral azole therapy (fluconazole 150 mg every 72 hours x 3 doses for severe acute infection, then weekly maintenance for 6 months)
  • Treatment of sexual partners is not routinely indicated
  • Harrison's Principles of Internal Medicine 22E, p. 1147

4. Cervicitis (Gonorrhea + Chlamydia)

Mucopurulent cervical discharge, cervical erosion/ulcer
Per WHO syndromic management guidelines:
  • Cefixime 400 mg orally, single dose (for gonorrhea)
  • Azithromycin 1 g orally, single dose (for chlamydia) - taken 1 hour before meals
If vaginitis and cervicitis are both present, treat for both.
  • Park's Textbook of Preventive and Social Medicine, p. 3600

Syndromic Management Approach (Resource-Limited Settings)

When laboratory testing is unavailable (WHO approach), empirical treatment covers the most likely causes:
Vaginitis (TV + BV + Candida) - treat all three:
  1. Secnidazole 2 g orally single dose (or Tinidazole 500 mg twice daily for 5 days)
    • Fluconazole 150 mg orally single dose OR Clotrimazole 500 mg vaginal pessary once
  3. Give Metoclopramide 30 minutes before Secnidazole to prevent GI intolerance
If cervicitis also present: add Cefixime 400 mg + Azithromycin 1 g.
  • Park's Textbook of Preventive and Social Medicine, p. 3594-3603

Special Populations

PopulationNotes
PregnancyMetronidazole is used throughout pregnancy for trichomoniasis (evidence supports safety). Treat BV in pregnancy to reduce risk of preterm birth.
Prepubertal girlsMost common causes are foreign body or non-specific vulvovaginitis (poor hygiene). Treat by correcting hygiene habits; candida is uncommon pre-puberty.
PostmenopausalConsider atrophic vaginitis - treat with topical estrogen cream.
HIV/immunocompromisedHigher risk of recurrence; more aggressive/prolonged treatment may be needed.

General Measures (All Cases)

  • Avoid vaginal douching (disrupts normal flora)
  • Maintain perineal hygiene (wipe front to back)
  • Avoid tight or synthetic undergarments
  • Avoid scented soaps/bath products near the vulva
  • Partner notification and treatment for trichomoniasis and cervicitis
  • Screen for concurrent STIs (HIV, HPV, syphilis) where relevant
