Treatment for 17-Year-Old Female with Candida and Bacterial Vaginosis

For a 17-year-old female with confirmed candida and bacterial vaginosis (BV) via vaginal swab, the recommended treatment is oral metronidazole 500 mg twice daily for 7 days for BV, along with either fluconazole 150 mg as a single oral dose or a topical azole for 1-7 days (depending on formulation) for candidiasis. 1, 2

Bacterial Vaginosis Treatment

First-line Treatment:

• Metronidazole 500 mg orally twice daily for 7 days 1, 2
  • Cure rate: approximately 95% 1
  • Patient must avoid alcohol during treatment and for 24 hours afterward 1, 2

Alternative Regimens:

• Metronidazole gel 0.75%, one full applicator (5g) intravaginally twice daily for 5 days 1, 2
• Clindamycin cream 2%, one full applicator (5g) intravaginally at bedtime for 7 days 1
  • Note: Clindamycin cream can weaken latex condoms and diaphragms 2

Vulvovaginal Candidiasis Treatment

Oral Option:

• Fluconazole 150 mg orally as a single dose 1, 2
  • Convenient single-dose treatment
  • Equally effective as topical treatments 3

Topical Options (OTC):

• Clotrimazole 1% cream: 5g intravaginally daily for 7-14 days 1
• Clotrimazole 2% cream: 5g intravaginally daily for 3 days 1
• Miconazole 2% cream: 5g intravaginally daily for 7 days 1
• Miconazole 4% cream: 5g intravaginally daily for 3 days 1
• Miconazole vaginal suppositories (various strengths) 1
• Tioconazole 6.5% ointment: 5g intravaginally in a single application 1

Prescription Topical Options:

• Terconazole 0.4% cream: 5g intravaginally daily for 7 days 1
• Terconazole 0.8% cream: 5g intravaginally daily for 3 days 1
• Terconazole 80 mg vaginal suppository: one suppository daily for 3 days 1
• Butoconazole 2% cream (single dose bioadhesive product): 5g intravaginally in a single application 1

Treatment Selection Considerations

For BV:

• Oral metronidazole is preferred for dual infection treatment to simplify the regimen
• Consider intravaginal options if patient has gastrointestinal intolerance to oral metronidazole
• Advise patient about alcohol restriction with metronidazole

For Candidiasis:

• Oral fluconazole offers convenience of single-dose treatment
• Topical treatments are equally effective but require multiple applications
• Patient preference may guide selection between oral and topical options

Follow-up Recommendations

• Follow-up visits are generally not necessary if symptoms resolve 1, 2
• Patient should return if symptoms persist or recur 2
• No long-term maintenance regimen is currently available for BV 1
• Recurrence of BV is common; alternative treatment regimens can be used for recurrent disease 1

Important Considerations

• Sexual abstinence until treatment completion is recommended 2
• Treatment of sexual partners is not routinely recommended for BV 1
• Self-medication with OTC preparations should only be advised for women previously diagnosed with VVC who experience recurrence of the same symptoms 2
• Daily lukewarm baths (30 minutes) can help remove discharge and debris 2

Diagnostic Pearls

• BV characteristics: homogeneous white thin discharge, fishy odor, pH >4.5 2
• Candidiasis characteristics: thick white "cottage cheese-like" discharge, intense itching, pH ≤4.5 2

This dual infection requires targeted treatment for both conditions to achieve complete resolution and prevent complications.
