# Miconazole Vaginal Suppository
## Overview
Miconazole is an imidazole antifungal agent used to treat vaginal yeast infections (vulvovaginal candidiasis).
## Primary Indications
Treatment of vulvovaginal candidiasis caused by susceptible strains of *Candida* species.
## Adult Dosing
**Option 1 (1-day treatment):** One 1200 mg vaginal suppository inserted vaginally at bedtime.
**Option 2 (3-day treatment):** One 200 mg vaginal suppository inserted vaginally at bedtime for 3 consecutive nights.
**Option 3 (7-day treatment):** One 100 mg vaginal suppository inserted vaginally at bedtime for 7 consecutive nights.
The 1200 mg formulation is typically the most convenient and often preferred for adherence.
## Pediatric Dosing
Safety and efficacy in pediatric patients have not been established for the vaginal suppository formulations. Use is not generally recommended.
## Dose Adjustments
No specific dose adjustments are recommended for hepatic or renal impairment, as systemic absorption is minimal.
## Contraindications
Hypersensitivity to miconazole or any component of the formulation.
## Adverse Effects
Common: Vaginal burning, itching, irritation, and cramping.
Less Common: Rash, urticaria.
## Key Drug Interactions
**CYP3A4 Inhibitor:** Miconazole is a moderate inhibitor of CYP3A4. Concomitant use with CYP3A4 substrates, particularly those with a narrow therapeutic index (e.g., warfarin, certain statins, immunosuppressants), may increase the plasma concentrations of these drugs, potentially leading to toxicity. Caution is advised, and dose reduction of the concomitant drug may be necessary.
## Monitoring
Monitor for symptom relief. If symptoms persist after completing therapy, consider re-evaluation for alternative diagnoses or resistant organisms.
## Clinical Pearls
* Complete the full course of treatment, even if symptoms improve sooner.
* Avoid sexual intercourse during treatment to prevent potential irritation and reduce the risk of transmitting the infection to a partner.
* If pregnancy is suspected or confirmed, consult a healthcare provider for appropriate management. While systemic absorption is low, topical antifungals are generally used with caution in pregnancy.
* Suppositories may cause some leakage; wearing a panty liner can help.
