# Miconazole Vaginal Pessary ## Overview Miconazole is an imidazole antifungal agent. Vaginal pessaries are inserted into the vagina for localized treatment of fungal infections. ## Primary Indications Vulvovaginal candidiasis (yeast infection). ## Adult Dosing * **100 mg pessary:** Insert one pessary vaginally at bedtime for 7 days. * **200 mg pessary:** Insert one pessary vaginally at bedtime for 3 days. * **100 mg pessary:** Insert two pessaries vaginally at bedtime for 3 days. * **Maximum dose:** Not explicitly defined for pessary form, but treatment duration should generally not exceed 7 days without consulting a healthcare provider. ## Pediatric Dosing * Data for pediatric use of miconazole vaginal pessaries is limited. Use should be guided by a healthcare provider. ## Dose Adjustments * No dose adjustment is typically required based on renal or hepatic impairment for topical vaginal administration. ## Contraindications * Hypersensitivity to miconazole or any component of the formulation. ## Adverse Effects * **Common:** Vaginal burning, itching, irritation. * **Less Common:** Pelvic cramps, rash. ## Key Drug Interactions * **CYP3A4 Inhibitors:** Miconazole is a moderate inhibitor of CYP3A4. Concomitant use with systemic drugs metabolized by CYP3A4 (e.g., certain statins, benzodiazepines, anticoagulants) may increase the risk of adverse effects from those drugs. While systemic absorption from vaginal pessaries is low, caution is advised, especially with prolonged or widespread use or in patients with impaired hepatic function. ## Monitoring * Monitor for resolution of symptoms (itching, burning, discharge). * Assess for signs of local irritation or allergic reaction. ## Clinical Pearls * Treatment duration varies by product strength and regimen. Ensure patient understands the specific product and duration prescribed. * Advise patients to avoid sexual intercourse during treatment. * Miconazole can weaken latex condoms and diaphragms. * Pessaries may cause leakage; advise patients to use a sanitary pad. * Complete the full course of treatment even if symptoms improve earlier. *** *This information is intended for healthcare professionals. Always verify current prescribing information with the manufacturer's package insert or other reliable clinical resources before making therapeutic decisions.*
