# Clotrimazole 1% Solution (Oral) ## Overview Clotrimazole is an imidazole antifungal agent. It works by inhibiting the synthesis of ergosterol, a vital component of fungal cell membranes. ## Primary Indications Oropharyngeal candidiasis (thrush). ## Adult Dosing Dissolve one 10 mg troche in the mouth slowly four times daily. Alternatively, for the solution: Apply a sufficient amount to cover affected areas in the mouth, approximately 10 mm, swish around the mouth and swallow, four times daily. The maximum dose is 50 mg per day. Treatment duration is typically 7 to 14 days. ## Pediatric Dosing For infants and children over 3 months of age: Apply a sufficient amount (approximately 5 mm, or half the adult dose) to cover affected areas in the mouth, swish around the mouth and swallow, four times daily. Alternatively, for troches: dissolve one 10 mg troche in the mouth slowly four times daily. Treatment for infants and children should typically continue for at least 7 days after symptoms resolve, or for several days after lesions disappear. ## Dose Adjustments No dose adjustments are typically needed for hepatic or renal impairment. ## Contraindications Known hypersensitivity to clotrimazole or any component of the formulation. ## Adverse Effects * **Common:** Abnormal liver function tests (elevated AST, ALT), rash, urticaria, pruritus, dyspnea. * **Less Common:** Nausea, vomiting, abdominal pain, diarrhea. ## Key Drug Interactions * **CYP450 Substrates:** Clotrimazole is a moderate inhibitor of CYP2C9 and a weak inhibitor of CYP3A4. Concomitant administration with drugs metabolized by these enzymes may increase their plasma concentrations. Caution and potential dose adjustment of the interacting drug may be necessary. Specific examples include warfarin, cyclosporine, and some statins. * **Nystatin:** May have antagonistic effects. ## Monitoring * Monitor for signs and symptoms of oral candidiasis. * Monitor liver function tests periodically, especially with prolonged use or in patients with pre-existing liver disease. * Observe for any signs of hypersensitivity or allergic reaction. ## Clinical Pearls * Advise patients to allow troches to dissolve slowly in the mouth without chewing. * For the solution, emphasize swishing thoroughly to ensure contact with all affected areas before swallowing. * Treatment should continue for at least 7 days after symptom resolution to prevent relapse. * Oral hygiene should be maintained to prevent reinfection. * Consider underlying conditions that may predispose to oral candidiasis (e.g., immunosuppression, diabetes). --- ***Disclaimer:** This information is intended for healthcare professionals.
