Indications: used for severe or disseminated fungal infections (invasive aspergillosis, cryptococcal meningitis, blastomycosis, coccidiomycosis)
Contraindications: allergy to class/drug
Dosage: Dosage varies significantly based on formulation. Generally, a single test dosage (1 mg in 20 mL of 5% dextrose) is infused over 20-30 minutes with close monitoring. If tolerated, then give a single daily dosage of 0.25mg/kg.
Half-life: Up to 14 days; depending on dosage
