# Miconazole vaginal pessary ## Overview Miconazole vaginal pessary is a topical azole antifungal agent used for the treatment of vulvovaginal candidiasis (yeast infections). ## Primary Indications Treatment of vulvovaginal candidiasis (VVC) caused by susceptible Candida species. ## 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. * **1500 mg pessary:** Insert one single-dose pessary vaginally at bedtime. ## Pediatric Dosing Safety and efficacy in pediatric patients have not been established for miconazole vaginal pessaries. Consult with a pediatrician for appropriate management. ## Dose Adjustments No dose adjustments are typically necessary for renal or hepatic impairment due to minimal systemic absorption. ## Contraindications * Hypersensitivity to miconazole or any component of the formulation. * Use with latex or rubber products (e.g., condoms, diaphragms), as miconazole can weaken them and lead to product failure. ## Adverse Effects * **Common:** Vaginal burning, itching, irritation, pelvic pain, headache. * **Less Common:** Rash, hives, abdominal pain. ## Key Drug Interactions * **Warfarin:** Miconazole can inhibit CYP2C9, potentially increasing the effect and INR of warfarin. Monitor INR closely, especially when initiating or discontinuing miconazole. * **CYP3A4 Substrates:** Miconazole can inhibit CYP3A4, potentially increasing plasma concentrations of drugs metabolized by this enzyme. Caution and monitoring may be warranted if used concurrently with sensitive CYP3A4 substrates. ## Monitoring * Monitor for signs and symptoms of VVC resolution. * Monitor for and manage any adverse effects. * If using concurrently with warfarin, monitor INR. ## Clinical Pearls * Complete the full course of therapy as directed, even if symptoms improve earlier. * Avoid sexual intercourse during treatment. * Consider partner treatment if reinfection is suspected or recurrent VVC occurs. * Wash hands thoroughly before and after insertion. * The pessary may cause leakage; wearing a panty liner can help. *** **Disclaimer:** This information is intended for clinical pharmacists and healthcare professionals.
