# Clotrimazole Drop ## Overview Clotrimazole is a synthetic broad-spectrum antifungal agent used topically and orally. It inhibits the synthesis of ergosterol, a vital component of fungal cell membranes. ## Primary Indications * Otic: Fungal infections of the ear canal (otomycosis). * Oral: Oropharyngeal candidiasis (thrush). ## Adult Dosing * **Otic:** Apply 3-4 drops into the affected ear canal twice daily. Duration of treatment is typically 7-14 days. * **Oral:** Dissolve one 10 mg troche in the mouth slowly every waking hour for 14 consecutive days. Max dose: 50 mg (5 troches) daily. ## Pediatric Dosing * **Otic:** Apply 3-4 drops into the affected ear canal twice daily. Duration of treatment is typically 7-14 days. Safety and efficacy in children under 3 years for otic use may not be established; consult local protocols. * **Oral:** Dissolve one 10 mg troche in the mouth slowly every waking hour for 14 consecutive days. Max dose: 50 mg (5 troches) daily. Safety and efficacy in infants are not established; consult local protocols. ## Dose Adjustments No dose adjustments are typically required for renal or hepatic impairment. ## Contraindications * Hypersensitivity to clotrimazole or any component of the formulation. ## Adverse Effects * **Otic:** Local irritation, burning, itching, dryness. * **Oral:** Gastrointestinal upset (nausea, vomiting), abnormal liver function tests, rash. ## Key Drug Interactions * **CYP3A4 Inhibitors:** Co-administration with strong CYP3A4 inhibitors may increase the risk of adverse effects from other drugs metabolized by this enzyme. However, systemic absorption of topical clotrimazole is minimal. * **Cyclosporine:** Clotrimazole can increase cyclosporine levels. ## Monitoring * Monitor for signs of clinical improvement and resolution of infection. * Monitor for adverse effects. * For oral use, liver function tests may be considered, especially with prolonged therapy or in patients with pre-existing liver disease. ## Clinical Pearls * Ensure the ear canal is clean and dry before administering otic drops. * Instruct patients to allow oral troches to dissolve completely in the mouth and not to chew or swallow them whole. * For oropharyngeal candidiasis, good oral hygiene is essential. Continue treatment for at least 48 hours after clinical cure. *** *This information is intended for healthcare professionals.
