# Miconazole vaginal pessary
## Overview
Miconazole is an imidazole antifungal agent used topically to treat fungal infections. The vaginal pessary formulation is designed for local delivery to the vaginal mucosa.
## Primary Indications
Vulvovaginal candidiasis (yeast infection).
## Adult Dosing
The typical adult dose is one miconazole vaginal pessary inserted into the vagina either once nightly for 7 nights, or as a single 100mg pessary inserted nightly for 3 nights, or a single 200mg pessary inserted nightly for 3 nights, or a single 1200mg pessary inserted as a single dose. Specific dosing regimens depend on the product strength and formulation available, and may follow local protocol.
## Pediatric Dosing
Safety and efficacy in pediatric patients below the age of 12 years have not been established. Dosing for pediatric patients 12 years and older is the same as adult dosing, though use should be guided by clinical judgment and local protocol.
## Dose Adjustments
No dose adjustments are typically required for 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 burning, itching, irritation, and lower abdominal cramping. Allergic reactions are possible.
## Key Drug Interactions
Miconazole is a moderate inhibitor of CYP3A4 and CYP2C9. Coadministration with warfarin may increase the risk of bleeding. Avoid concurrent use with other vaginal products unless directed by a healthcare professional.
## Monitoring
Monitor for symptom resolution and recurrence of infection. Assess for adverse effects.
## Clinical Pearls
Complete the full course of therapy as prescribed, even if symptoms improve sooner. Pessaries should be inserted as high as possible into the vagina, preferably at bedtime.urses should advise patients to avoid sexual intercourse during treatment. Some miconazole products can weaken latex condoms and diaphragms, potentially leading to failure.
