Treatment for Thrush
For uncomplicated vulvovaginal candidiasis (thrush), either topical azole antifungals applied intravaginally or a single 150 mg oral dose of fluconazole are equally effective first-line treatments, with topical agents achieving 80-90% cure rates. 1
Uncomplicated Vulvovaginal Candidiasis
First-Line Treatment Options
Topical intravaginal azole therapy is highly effective, with multiple equivalent options available 1:
- Short-course regimens (1-3 days) are as effective as longer courses for uncomplicated cases 1
- Clotrimazole 1% cream 5g intravaginally for 7-14 days 1
- Clotrimazole 100 mg vaginal tablet for 7 days 1
- Clotrimazole 500 mg vaginal tablet as single application 1
- Miconazole 2% cream 5g intravaginally for 7 days 1, 2
- Miconazole 200 mg vaginal suppository for 3 days 1
- Terconazole 0.8% cream 5g intravaginally for 3 days 1
- Butoconazole 2% cream 5g intravaginally for 3 days 1
Oral fluconazole 150 mg as a single dose is equally effective as topical therapy and offers superior convenience 1, 3. Clinical cure or improvement occurs in 94% of patients by day 14, with mycologic cure in 77% 3.
Important caveat: Topical azole creams and suppositories are oil-based and may weaken latex condoms and diaphragms 1, 2. Patients should avoid vaginal intercourse during treatment 2.
Alternative Agents
- Nystatin 100,000-unit vaginal tablet daily for 14 days is less effective than azoles but remains an option 1
- Topical azoles are more effective than nystatin, with azoles achieving significantly better outcomes 4
Severe or Complicated Vulvovaginal Candidiasis
For severe acute disease, fluconazole 150 mg every 72 hours for 2-3 total doses is recommended 1.
Non-albicans Candida Species
For C. glabrata vulvovaginitis unresponsive to oral azoles 1:
- Boric acid 600 mg intravaginally daily for 14 days (administered in gelatin capsule) 1
- Nystatin intravaginal suppositories 100,000 units daily for 14 days 1
- Topical 17% flucytosine cream alone or combined with 3% amphotericin B cream daily for 14 days 1
Recurrent Vulvovaginal Candidiasis
For recurrent infections (≥4 episodes per year), use 10-14 days of induction therapy with topical agent or oral fluconazole, followed by fluconazole 150 mg weekly for 6 months as maintenance 1.
Oropharyngeal Candidiasis (Oral Thrush)
For mild oropharyngeal candidiasis affecting the mouth and lips 5:
- Clotrimazole troches 10 mg used 5 times daily for 7-14 days 5
- Miconazole mucoadhesive buccal 50 mg tablet applied to mucosal surface over canine fossa once daily for 7-14 days 5
Alternative topical options 5:
- Nystatin suspension (100,000 U/mL) 4-6 mL four times daily for 7-14 days 5
- Nystatin pastilles (200,000 U each) 1-2 pastilles four times daily for 7-14 days 5
For moderate to severe oropharyngeal candidiasis, oral systemic therapy with fluconazole 100-200 mg daily for 7-14 days is preferred over topical options 5. Single-dose fluconazole 150 mg has shown 96.5% efficacy for oral thrush in palliative care patients 6.
Treatment Duration Considerations
- Pregnancy: Seven-day treatment courses are necessary rather than shorter regimens used in non-pregnant women 4
- General population: Treatment should continue until clinical resolution, typically 7-14 days 5
- Most patients experience symptom improvement within 1 day but require the full 7-day course for complete relief 2
Key Clinical Pitfalls
Avoid self-treatment without prior diagnosis 2:
- Women should only self-treat with over-the-counter preparations if previously diagnosed by a physician and experiencing identical recurrent symptoms 1
- Symptoms persisting beyond 3 days or lasting more than 7 days require physician evaluation 2
Red flags requiring immediate medical evaluation 2:
- Lower abdominal, back, or shoulder pain with fever, chills, nausea, vomiting, or foul-smelling discharge (may indicate pelvic inflammatory disease) 2
- Recurrent infections (≥3 episodes in 6 months) suggesting underlying conditions like diabetes or immunosuppression 2
