From the Guidelines
Recurrent vaginal thrush is best treated with 10-14 days of induction therapy with a topical agent or oral fluconazole, followed by fluconazole 150 mg weekly for 6 months. This approach is based on the strong recommendation and high-quality evidence from the 2016 update by the Infectious Diseases Society of America 1. The treatment aims to provide immediate relief and prevent future recurrences.
Key Considerations
- Induction therapy can be achieved with either a topical agent or oral fluconazole for 10-14 days.
- Maintenance therapy with fluconazole 150 mg weekly for 6 months is crucial in preventing recurrences.
- It is essential to note that partners generally do not need treatment unless they have symptoms.
Additional Measures
- Avoiding irritants like scented products, tight synthetic underwear, and excessive washing of the genital area can help in managing the condition.
- Probiotics containing Lactobacillus species may help prevent recurrence by maintaining healthy vaginal flora, although the evidence is mixed.
- If symptoms persist despite appropriate treatment, it is necessary to consider alternative diagnoses or resistant Candida species that may require different antifungal agents.
Treatment Rationale
The recommended treatment approach is based on the high-quality evidence from the 2016 clinical practice guideline for the management of candidiasis 1, which emphasizes the importance of both induction and maintenance therapy in managing recurrent vulvovaginal candidiasis.
From the FDA Drug Label
Vaginal candidiasis: Two adequate and well-controlled studies were conducted in the U. S. using the 150 mg tablet. ... The remaining one-fourth of enrolled patients had recurrent vaginitis (≥4 episodes/12 months) and achieved 57% clinical cure, 47% mycologic eradication, and 40% therapeutic cure

From the Research
Treatment Options for Recurrent Vaginal Thrush
- The treatment of recurrent vaginal thrush, also known as recurrent vulvovaginal candidiasis (RVVC), can be challenging, with various options available, including topical and oral medications 3, 4, 5, 6, 7.
- Topical treatments, such as clotrimazole, miconazole, terconazole, and intravaginal boric acid, are suggested recommendations for recurrent vulvovaginitis caused by both Candida albicans and nonalbicans species 3.
- Oral fluconazole is also a commonly used treatment for RVVC, with studies showing its effectiveness in reducing the risk of recurrence 4, 6, 7.
- A combined approach, using both systemic and topical treatments, has been proposed as a new therapeutic approach to RVVC, with the goal of addressing the recurrent infection aggressively and preventing new events 4.
Maintenance Therapy
- Maintenance therapy is an important aspect of treating RVVC, with the goal of preventing recurrence and reducing the risk of long-term complications 3, 5, 6.
- Weekly oral oteseconazole, weekly oral fluconazole/itraconazole, and weekly topical clotrimazole have been shown to be effective in reducing the risk of RVVC recurrence during active treatment 6.
- After discontinuation of therapy, weekly oteseconazole has been shown to be significantly more effective in reducing the occurrence of late clinical and mycological RVVC recurrences than all other types of treatment tested 6.
Comparison of Treatment Options
- A study comparing single-dose oral fluconazole with 3-day intravaginal clotrimazole found that fluconazole was more effective in the long term, relieved symptoms more rapidly, and was as safe as clotrimazole 7.
- Another study found that weekly maintenance therapy with oral fluconazole/itraconazole, oteseconazole, or topical clotrimazole was equally effective in preventing early RVVC recurrence 6.
- The choice of treatment should be based on the individual patient's needs and medical history, as well as the specific characteristics of the infection, such as the species of Candida present 3, 5.
