Introduction

Voriconazole is a powerful antifungal medication used to treat serious fungal infections. It belongs to the triazole class of antifungals and works by blocking the fungus’s ability to grow and reproduce. It is usually prescribed for moderate to severe infections, especially in people with weakened immune systems.

Voriconazole is available in tablet, injection, and oral suspension forms.
