# Miconazole Vaginal Pessary ## Overview Miconazole is an imidazole antifungal agent. The vaginal pessary formulation is used for the topical treatment of vulvovaginal candidiasis (yeast infections). ## Primary Indications * Treatment of vulvovaginal candidiasis (yeast infection) caused by susceptible *Candida* species. ## Adult Dosing The typical dosage is one miconazole vaginal pessary inserted vaginally at bedtime for 3 nights. Some products may have a 1-day or 7-day regimen. Follow the specific product's instructions. ## Pediatric Dosing Dosing in pediatric patients is not well-established for the vaginal pessary formulation. Use with caution and consider adult dosing as a reference if deemed appropriate by a healthcare provider. ## Dose Adjustments No dose adjustments are typically needed based on renal or hepatic impairment due to minimal systemic absorption. ## Contraindications * Hypersensitivity to miconazole or any component of the formulation. ## Adverse Effects Common adverse effects include vaginal itching, burning, irritation, and lower abdominal cramping. ## Key Drug Interactions Miconazole is a potent inhibitor of CYP3A4. While systemic absorption is minimal with vaginal administration, theoretical potential exists for drug interactions, especially with prolonged or extensive use. Caution is advised if co-administered with warfarin or other susceptible CYP3A4 substrates. ## Monitoring * Monitor for symptom relief. * Assess for vaginal irritation or allergic reactions. ## Clinical Pearls * Instruct patients on proper insertion technique. * Advise patients that treatment may last several days, and symptoms may not fully resolve immediately. * Avoid sexual intercourse during treatment. * Miconazole may weaken latex condoms and diaphragms. *** *This information is intended for healthcare professionals.
