Introduction

Itraconazole is an antifungal medication used to treat a wide range of fungal infections. It belongs to the class of drugs known as triazole antifungals, which work by stopping fungi from growing and multiplying. It is commonly prescribed when infections are moderate to severe or when other antifungals are not effective.

Why Itraconazole Is Used

Itraconazole is prescribed to treat infections caused by fungi or yeasts. Doctors recommend it when:

• A fungal infection is confirmed or strongly suspected
• Standard antifungals (like fluconazole) may not work
• Long-term antifungal treatment is needed

Itraconazole helps by:

• Killing or inhibiting fungal growth
• Reducing symptoms like itching, redness, or pain
• Preventing the spread of the infection

Systemic (Internal) Fungal Infections

• Histoplasmosis
• Blastomycosis
• Aspergillosis (in some cases)
