Why is this medication prescribed?

Vfend is the brand name for voriconazole, an antifungal medication. It is prescribed to treat various fungal infections, including those caused by Candida species, Aspergillus species, and certain other fungi. Voriconazole works by interfering with the synthesis of ergosterol, a component of the fungal cell membrane, disrupting the growth and replication of the fungus.

How should this medicine be used?

Here are general guidelines for using Vfend, but it’s crucial to follow your healthcare provider’s specific instructions:

• Dosage: The dosage of Vfend can vary based on the type and severity of the fungal infection, as well as individual patient factors. Your doctor will determine the appropriate dosage for your condition.
