# Miconazole Vaginal Pessary
## Overview
Miconazole is an imidazole antifungal agent.
## Primary Indications
Treatment of vulvovaginal candidiasis (yeast infection).
## Adult Dosing
**Miconazole 100 mg vaginal suppository:** Insert one suppository vaginally at bedtime for 7 consecutive nights.
**Miconazole 200 mg vaginal suppository:** Insert one suppository vaginally at bedtime for 3 consecutive nights.
**Miconazole 1200 mg vaginal suppository:** Insert one suppository vaginally at bedtime as a single dose.
*Maximum dose depends on the specific product formulation and duration of therapy. For most over-the-counter products, adherence to package instructions is recommended.*
## Pediatric Dosing
Safety and efficacy in pediatric patients below 12 years of age have not been established. Data for older pediatric patients is limited, and use should be based on clinical judgment and physician guidance.
## Dose Adjustments
No specific dose adjustments are necessary for renal or hepatic impairment.
## Contraindications
Hypersensitivity to miconazole or any component of the formulation.
## Adverse Effects
Common adverse effects include vulvovaginal burning, itching, irritation, and lower abdominal cramping.
## Key Drug Interactions
Miconazole is a moderate inhibitor of CYP3A4.
* **Warfarin:** Increased risk of bleeding. Monitor INR closely. Dose adjustments of warfarin may be necessary.
* **CYP3A4 substrates:** Potential for increased plasma concentrations of drugs metabolized by CYP3A4 (e.g., certain calcium channel blockers, benzodiazepines, statins, immunosuppressants). Use with caution.
## Monitoring
Monitor for symptom improvement. Assess for signs of local irritation or allergic reaction.
## Clinical Pearls
* Vaginal suppositories should be inserted high into the vagina, preferably at bedtime to minimize leakage.
* Avoid sexual intercourse during treatment.
* Consider concurrent treatment of sexual partners if recurrent infections occur, though this is not standard practice for uncomplicated vulvovaginal candidiasis.
* If symptoms do not improve after completion of therapy, or if they worsen, re-evaluate the diagnosis and consider alternative treatments.
