• Concurrent use of astemizole, cisapride, or terfenadine with ketoconazole tablets is contraindicated, because serious cardiovascular adverse events (including death, ventricular tachycardia, and torsades de pointes) have occurred.
Alters fungal cell membranes, resulting in increased permeability, growth inhibition, and ultimately, cell death
Shampoo: 1%, 2%
Tablets: 200 mg
⊘Indications and dosages
➣ Blastomycosis; chronic mucocutaneous candidiasis; oral thrush; candiduria; coccidioidomycosis; histoplasmosis; chromomycosis; paracoccidioidomycosis; mucocutaneous or vaginal candidiasis
Adults: 200 to 400 mg P.O. daily
Children ages 2 and older: 3.3 to 6.6 mg/kg P.O. as a single daily dose. Duration depends on infection: for candidiasis, 1 to 2 weeks; other systemic mycoses, 6 months; recalcitrant dermatophyte infections involving glabrous skin, 4 weeks. Chronic mucocutaneous candidiasis requires maintenance therapy.
➣ Scaling caused by dandruff or seborrheic dermatitis
Adults: 2% shampoo applied topically twice weekly for 4 weeks, then as needed to control symptoms, with at least 3 days between applications; or 1% shampoo applied topically q 3 to 4 days for up to 8 weeks, then as needed to control dandruff
➣ Tinea corporis; tinea cruris; tinea versicolor; tinea pedis, cutaneous candidiasis
