# Miconazole Vaginal Pessary
## Overview
Miconazole is an imidazole antifungal agent.
## Primary Indications
Treatment of vulvovaginal candidiasis (yeast infections).
## Adult Dosing
Typically, a single 1200 mg miconazole vaginal suppository (pessary) inserted vaginally is used for treatment. Alternatively, a 200 mg suppository can be used nightly for 3 nights, or a 100 mg suppository can be used nightly for 7 nights.
## Pediatric Dosing
Safety and efficacy in pediatric patients have not been established for the miconazole vaginal pessary.
## Dose Adjustments
No dose adjustments are typically required for renal or hepatic impairment.
## Contraindications
Known 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 moderate inhibitor of CYP3A4 and may increase the plasma concentrations of drugs metabolized by this enzyme (e.g., warfarin, certain statins, some immunosuppressants). Concomitant use with oral miconazole is generally avoided due to increased systemic exposure and risk of drug interactions.
## Monitoring
Monitor for signs and symptoms of vaginal candidiasis resolution and for any adverse effects.
## Clinical Pearls
- Advise patients to insert the pessary at bedtime to minimize leakage.
- If symptoms persist or worsen after completing therapy, re-evaluate the diagnosis.
- Avoid intercourse during treatment.
- Condoms and diaphragms may be damaged by the excipients in the vaginal product, reducing their effectiveness as a contraceptive or STI prevention method.
