Ketoconazole (Oral): The Systemic Antifungal Treatment
What is Oral Ketoconazole?
Oral Ketoconazole is a systemic antifungal used to treat serious fungal infections that affect internal organs. It is commonly used to treat conditions like histoplasmosis, blastomycosis, and candidiasis when topical treatments are ineffective.
