# Miconazole Vaginal Pessary
## Overview
Miconazole is an imidazole antifungal agent used to treat vaginal yeast infections (vulvovaginal candidiasis).
## Primary Indications
Treatment of vaginal yeast infections (vulvovaginal candidiasis) caused by *Candida albicans*.
## Adult Dosing
Available as a 100 mg vaginal suppository (pessary).
* **Option 1:** Insert one 100 mg vaginal suppository high into the vagina at bedtime for 7 consecutive nights.
* **Option 2:** Insert two 100 mg vaginal suppositories high into the vagina at bedtime for 3 consecutive nights.
* **Option 3 (less common, may not be available):** A single-dose 1200 mg vaginal suppository may be used.
## Pediatric Dosing
Dosing for pediatric patients is not well-established. Use in pediatric patients should be based on clinical judgment and may require consultation with a specialist.
## Dose Adjustments
No dose adjustments are necessary for renal or hepatic impairment.
## Contraindications
* Hypersensitivity to miconazole or any component of the formulation.
## Adverse Effects
* **Common:** Vaginal burning, itching, irritation.
* **Less Common:** Lower abdominal cramping, headache, rash.
## Key Drug Interactions
* **Warfarin:** Miconazole (especially oral) can significantly increase warfarin levels. While vaginal administration poses a lower risk, caution and INR monitoring are advised if the patient is also on warfarin, particularly with prolonged use or signs of bleeding.
* **CYP3A4 Inhibitors:** Miconazole is a potent inhibitor of CYP3A4. Although systemic absorption from vaginal administration is minimal, theoretical interactions with drugs metabolized by CYP3A4 (e.g., certain statins, calcium channel blockers, benzodiazepines) cannot be entirely excluded with extensive or prolonged use.
## Monitoring
* Clinical signs and symptoms of vaginal candidiasis.
* Monitor for local irritation or allergic reactions.
* Monitor INR if patient is on warfarin.
## Clinical Pearls
* Treatment should be completed even if symptoms improve before the prescribed course is finished.
* Avoid intercourse during treatment to prevent potential transmission and to avoid irritation from the medication.
* Pessaries may not be fully absorbed and could lead to discharge. Wearing a panty liner may be helpful.
* If symptoms do not improve within 3 days or are completely resolved within 7 days, consult a healthcare provider. Recurrent infections may require different treatment strategies.
