Can terconazole (Terazol) vaginal cream be used on a daily basis?

From the Guidelines

Terconazole (Terazol) vaginal cream should not be used on a daily basis long-term, but rather for a specific duration as prescribed, typically 7 days for the 0.4% cream and 3 days for the 0.8% cream, as recommended by the 2021 Centers for Disease Control and Prevention guidelines 1. The recommended regimens for treatment of vulvovaginal candidiasis using terconazole are:

• 0.4% cream: 5 g intravaginally daily for 7 days
• 0.8% cream: 5 g intravaginally daily for 3 days Prolonged daily use of terconazole can disrupt the normal vaginal flora and potentially lead to drug resistance, highlighting the importance of adhering to the prescribed treatment duration 1. Key considerations for the treatment of vulvovaginal candidiasis include:
• Diagnosis: Culture remains the gold standard for diagnosis, but microscopy and clinical suspicion are also used due to the delay in culture results 1.
• Treatment options: Various over-the-counter and prescription intravaginal agents are available, including terconazole, clotrimazole, and miconazole, as well as oral agents like fluconazole 1.
• Potential risks: Misdiagnosis and unnecessary treatment can occur due to the limitations of current diagnostic methods, emphasizing the need for accurate diagnosis and appropriate treatment 1.

From the FDA Drug Label

• The drug label explicitly states the dosage and administration instructions.
• The treatment duration is limited to 7 days, and the diagnosis should be reconfirmed before prescribing another course of therapy 2.

From the Research
