What are the treatment options for vulvovaginal candidiasis (VVC)?

From the Guidelines

Vaginal yeast infections should be treated with over-the-counter or prescription antifungal medications, with fluconazole 150 mg as a single dose being a highly effective option for severe or recurrent infections, as recommended by the 2021 Centers for Disease Control and Prevention guidelines 1.

Treatment Options

The treatment of vaginal yeast infections can be approached with various options, including:

• Over-the-counter intravaginal agents such as clotrimazole, miconazole, and tioconazole, which are available in cream, suppository, or ointment form, with dosing regimens ranging from 1 to 14 days 1.
• Prescription intravaginal agents like butoconazole, terconazole, which offer alternative treatment options for patients who may not respond to over-the-counter medications 1.
• Oral agent fluconazole 150 mg, which is a highly effective single-dose treatment for severe or recurrent infections, as supported by the 2021 CDC guidelines 1.

Diagnosis and Considerations

It's essential to note that diagnosis of vaginal yeast infections can be challenging, with microscopy and clinical suspicion having poor sensitivity, while yeast cultures can lead to a delay in diagnosis and treatment 1. Molecular testing, such as polymerase chain reaction (PCR), has shown high clinical accuracy and may become a valuable tool in diagnosing vaginal yeast infections 1.

Recommendations

For uncomplicated vaginal yeast infections, over-the-counter antifungal medications containing miconazole or clotrimazole are recommended as first-line treatment, with fluconazole 150 mg as a single dose being a highly effective option for severe or recurrent infections 1. During treatment, it's crucial to maintain good hygiene, avoid douching, scented hygiene products, and tight-fitting clothing, and keep the genital area clean and dry. If symptoms persist or recur frequently, consultation with a healthcare provider is necessary for appropriate management.

From the FDA Drug Label

Vaginal candidiasis: Two adequate and well-controlled studies were conducted in the U. S. using the 150 mg tablet. In both, the results of the fluconazole regimen were comparable to the control regimen (clotrimazole or miconazole intravaginally for 7 days) both clinically and statistically at the one month post-treatment evaluation The therapeutic cure rate, defined as a complete resolution of signs and symptoms of vaginal candidiasis (clinical cure), along with a negative KOH examination and negative culture for Candida (microbiologic eradication), was 55% in both the fluconazole group and the vaginal products group

Treatment for vaginal yeast infection:

• Fluconazole (PO) 150 mg tablet is effective for the treatment of vaginal candidiasis, with a therapeutic cure rate of 55% [@\1@].
• Miconazole (PV) is also used for the treatment of vaginal yeast infections, and it is available as a vaginal insert and external vulvar cream [@\3@]. Key points:
• Fluconazole and miconazole are both effective treatments for vaginal yeast infections.
• The therapeutic cure rate for fluconazole is 55%, while the efficacy of miconazole is not directly compared to fluconazole in the provided text.
• It is essential to follow the recommended dosage and administration instructions for each medication to ensure effective treatment and minimize potential side effects.

From the Research

Treatment Options for Vaginal Yeast Infection

• Local treatment is the first line of choice in cases of acute vaginal yeast infection, with a success rate of 84-90% 2
• Various local preparations are available, including Nizoral, Clotrimazole, Canesten, Gyno-Daktarine, Gyno-Pevaryl, and Miconazole 2
• Broad spectrum oral antimycotics, such as Nystatine, Ketoconazole, Fluconazole, and itraconazole, are also used to treat vaginal yeast infections 2

Comparison of Treatment Regimens

• Clotrimazole vaginal tablet and oral fluconazole have been compared in terms of efficacy and safety, with similar clinical cure rates and mycological cure rates 3
• A single dose of oral fluconazole 150 mg has been shown to be as effective as intra-vaginal clotrimazole treatment for acute vulvovaginal candidiasis 4
• A combined treatment regimen using systemic antimicrobial drug therapy with oral fluconazole and topical drug therapy using metronidazole and clotrimazole has been proposed for recurrent candidiasis 5

Recurrent and Resistant Forms of Vaginal Candidosis

• The treatment of chronic, recurrent, and resistant forms of vaginal candidosis requires prolonged local and/or systemic therapy for a period of at least 6 months 2
• Different regimes of therapy have been proposed, including the use of fluconazole as an oral drug of choice for continuous treatment of vaginal yeast infection 2
• A new therapeutic approach to recurrent vulvovaginal candidiasis has been discussed, involving a combined scheme using both systemic and topical drug therapy, as well as adjuvant oral probiotic therapy 5
