# Miconazole Vaginal Pessary (Suppository) ## Overview Miconazole is an imidazole antifungal agent that inhibits the synthesis of ergosterol, a vital component of fungal cell membranes. It is primarily used topically for vulvovaginal candidiasis. ## Primary Indications Treatment of vulvovaginal candidiasis (yeast infections). ## Adult Dosing * **100 mg suppository:** Insert one suppository intravaginally once daily at bedtime for 7 consecutive days. * **200 mg suppository:** Insert one suppository intravaginally once daily at bedtime for 3 consecutive days. * **1200 mg suppository:** Insert one suppository intravaginally as a single dose (usually at bedtime). ## Pediatric Dosing Not typically indicated for prepubertal children. Safety and efficacy in pediatric patients <12 years have not been established. Diagnosis should be confirmed by a healthcare provider before use in adolescents. ## Dose Adjustments No specific dosage adjustments are required for renal or hepatic impairment due to minimal systemic absorption. ## Contraindications * Hypersensitivity to miconazole or any component of the formulation. * Not indicated for the treatment of recurrent yeast infections or symptoms associated with systemic infection (e.g., fever, pelvic/abdominal pain). ## Adverse Effects * **Local:** Vulvovaginal burning, stinging, itching, irritation, or pelvic cramping. * **Systemic:** Rare (due to low absorption), but may include headache or skin rash. ## Key Drug Interactions * **Warfarin:** Although systemic absorption is low, vaginal miconazole may potentially increase the risk of bleeding in patients on anticoagulants. Monitor INR if used concurrently. ## Monitoring * Monitor for symptom resolution. If symptoms persist beyond 7 days or recur within 2 months, the patient should be re-evaluated to rule out other causes (e.g., bacterial vaginosis) or resistant organisms. ## Clinical Pearls * **Administration:** The suppository should be inserted high into the vagina using the provided applicator or as directed by the product insert. * **Patient Education:** Use at bedtime to minimize leakage. The suppository may weaken latex condoms or diaphragms; avoid barrier contraception during treatment. * **Hygiene:** Advise patients to refrain from sexual intercourse and tampon use during treatment. * **Uncertainty:** If the patient has never been diagnosed with a yeast infection by a physician, they should be advised to seek clinical evaluation before initiating over-the-counter treatment. *** *Disclaimer: This information is for educational purposes only.
