From the Guidelines
Yes, certain capsules can be placed vaginally, but this should only be done with medications specifically designed and prescribed for vaginal administration, such as boric acid capsules, which have been shown to be effective in treating vulvovaginal candidiasis, particularly in cases of azole-resistant Candida species 1.
Key Considerations
- Vaginal capsules should only be used under the guidance of a healthcare provider, as improper use can lead to irritation, infection, or other adverse effects.
- The most recent and highest quality study, published in 2016, recommends the use of topical or oral antifungal agents for the treatment of vulvovaginal candidiasis, with boric acid capsules being a viable option for complicated cases 1.
- When using vaginal capsules, it is essential to follow the specific instructions provided with the medication, wash hands before and after insertion, and complete the full course of treatment even if symptoms improve quickly.
Important Details
- The 2016 study emphasizes the importance of confirming the diagnosis of vulvovaginal candidiasis through a wet-mount preparation with saline and 10% potassium hydroxide to demonstrate the presence of yeast or hyphae and a normal pH (4.0–4.5) before proceeding with empiric antifungal therapy 1.
- The study also notes that uncomplicated vulvovaginal candidiasis can be effectively treated with either single-dose fluconazole or short-course fluconazole for 3 days, both of which achieve >90% response 1.
- Complicated vulvovaginal candidiasis, on the other hand, requires more prolonged treatment, and boric acid capsules may be a suitable option in cases of azole-resistant Candida species 1.

From the Research
Vaginal Capsule Administration
- The human vagina is a potential route for drug delivery, offering a valuable space for the administration of specifically designed carrier systems for both local and systemic applications 2.
- Various drug delivery platforms are suitable for intravaginal administration, including hydrogels, vaginal tablets, pessaries/suppositories, particulate systems, and intravaginal rings 2.
- The vagina is a highly effective site for drug delivery, particularly in women's health, allowing for the administration of lower doses, steady drug levels, and less frequent administration than the oral route 3.
Types of Vaginal Drug Administration
- Vaginal tablets, such as clotrimazole, have been used to treat vaginal candidiasis, producing cure rates comparable to those of conventional nystatin vaginal tablets 4.
- Intravaginal clotrimazole has been compared to single-dose oral fluconazole in the treatment of vaginal candidiasis, with fluconazole showing more effective long-term results and faster symptom relief 5.
- The vaginal route of drug delivery is acceptable and may even be a preferable route of administration for many drugs, particularly hormones, whether for contraception or postmenopausal estrogen therapy 3.
Women-Specific Routes of Administration
- The woman's body presents unique anatomical features that can constitute valuable routes for the administration of drugs, including genitalia, changes occurring during pregnancy, and the female breast 6.
- Understanding the possibilities and limitations of women-specific routes is of key importance for the development of new preventative, diagnostic, and therapeutic strategies that will ultimately contribute to the advancement of women's health 6.
