# Miconazole Vaginal Pessary
## Overview
Miconazole is an imidazole antifungal agent used to treat vaginal yeast infections.
## Primary Indications
Vulvovaginal candidiasis (yeast infection).
## Adult Dosing
Available as a 100 mg, 200 mg, or 1200 mg vaginal insert (pessary).
* **100 mg pessary:** Insert 1 pessary vaginally at bedtime for 7 days.
* **200 mg pessary:** Insert 1 pessary vaginally at bedtime for 3 days.
* **1200 mg pessary:** Insert 1 pessary vaginally as a single dose.
Dosing regimen may vary based on product availability and clinical guidelines.
## Pediatric Dosing
Safety and efficacy in pediatric patients under 12 years of age have not been established. Consult product labeling or local protocol for guidance in adolescents.
## Dose Adjustments
No specific dose adjustments are necessary for hepatic or renal impairment.
## Contraindications
* Hypersensitivity to miconazole or any component of the formulation.
* Use with oral ketoconazole or other CYP3A4 inhibitors (due to risk of increased plasma concentrations of these drugs).
## Adverse Effects
* **Common:** Vaginal burning, itching, irritation, lower abdominal cramping.
* **Less Common:** Headache, rash.
## Key Drug Interactions
* **CYP3A4 Inhibitors:** Miconazole is a moderate inhibitor of CYP3A4. Concomitant use with drugs metabolized by CYP3A4 (e.g., certain statins, calcium channel blockers, immunosuppressants) may increase the risk of adverse effects from those drugs. Use with oral ketoconazole is contraindicated.
* **Warfarin:** Miconazole may increase the anticoagulant effect of warfarin. Monitor INR closely.
## Monitoring
* Clinical signs and symptoms of vulvovaginal candidiasis.
* For patients on warfarin, monitor INR.
## Clinical Pearls
* Treatment duration depends on the strength of the pessary used.
* Avoid sexual intercourse during treatment.
* Partner treatment is generally not recommended unless they have symptomatic candidiasis.
* If symptoms persist or worsen after treatment, re-evaluate diagnosis and consider alternative therapies.
* Pregnancy: While systemic absorption is minimal, use during the first trimester should be avoided unless clinically necessary and benefits outweigh risks. Consult prescribing information for specific recommendations.
