From the Guidelines
For resistant vaginal thrush, I strongly recommend a 10-14 day induction therapy with a topical agent or oral fluconazole, followed by fluconazole 150mg weekly for 6 months, as this approach has been shown to be effective in managing recurring vulvovaginal candidiasis 1. This recommendation is based on the most recent and highest quality evidence available, which suggests that this treatment strategy can help reduce the frequency and severity of recurrent infections. Some key points to consider when implementing this treatment plan include:
- Ensuring compliance with the full treatment course to minimize the risk of resistance development
- Addressing contributing factors such as poor hygiene, tight clothing, and uncontrolled diabetes
- Considering the use of alternative treatments, such as boric acid vaginal suppositories, for non-albicans Candida species that may be resistant to standard azole therapies
- Evaluating the need for treatment of sexual partners if reinfection occurs It is also important to note that resistant thrush can be caused by a variety of factors, including biofilm formation, incomplete previous treatments, and the presence of less common Candida species, and therefore, a comprehensive approach that takes into account these factors is essential for effective management 1.

From the Research
Resistant Vaginal Thrush Treatment
- Resistant vaginal thrush is a challenging condition to treat, especially when caused by azole-resistant Candida species 2.
- The treatment of vulvovaginal candidiasis (VVC) depends on the severity of the symptoms and the species of Candida involved 3.
- For acute cases, treatment with antimycotic agents such as clotrimazole, fluconazole, and itraconazole is usually effective 3, 4, 5.
- However, for cases caused by non-albicans species, such as Candida glabrata, treatment can be more challenging, and alternative options such as boric acid or flucytosine may be recommended 3.
- In cases of azole-resistant VVC, treatment options are limited, and new therapeutic strategies are urgently needed 2.
- Itraconazole has been shown to be effective in the treatment of acute and recurrent VVC, with cure rates of up to 97.1% in patients with the acute sporadic form 6.
- Suppressive therapy with azole drugs may be necessary in patients with recurrent VVC to prevent relapses 6.
Treatment Options
- Clotrimazole: a topical antimycotic agent effective in treating VVC 3, 4, 5.
- Fluconazole: an oral antimycotic agent effective in treating VVC, but may not be as effective in cases caused by non-albicans species 3, 4, 5.
- Itraconazole: an oral antimycotic agent effective in treating acute and recurrent VVC 5, 6.
- Boric acid: an alternative treatment option for cases caused by non-albicans species, but not approved for use in all countries 3.
- Flucytosine: an alternative treatment option for cases caused by non-albicans species, but not widely available 3.
