Table of contents:

Vfend is a medication used in the treatment of serious fungal infections. It is typically used to treat infections caused by Aspergillus and Candida fungi, among others. It contains the active substance voriconazole, which belongs to a class of antifungal drugs called azoles.

Vfend works by inhibiting the synthesis of ergosterol, a key component of fungal cell membranes, which leads to the disruption of fungal cell walls and the death of the fungus. By doing so, Voriconazole impairs the fungal cell membrane, leading to the death of the fungi. This mechanism of action distinguishes Voriconazole from other types of antifungal medications, such as azoles, which work by inhibiting the synthesis of ergosterol.

Uses and Dosage

Voriconazole is available in tablet form to be taken orally. It should be taken at the same time every day, every 12 hours, as directed by your doctor. To ensure the best results, take Voriconazole at evenly spaced times and, if necessary, set a reminder to help you remember. Take Voriconazole at least 1 hour before or 1 hour after meals.

The recommended dosage of Voriconazole may vary depending on the patient's age and weight, and the severity and type of infection being treated. The typical recommended dosage for adults is 200 mg orally every 12 hours, and the dose may be increased to 300 mg orally every 12 hours depending on the patient's response and the severity of the infection. For pediatric patients, the dosage will be adjusted based on their weight and age.

Continue to take the full prescribed amount of Voriconazole, even if symptoms improve before the end of the treatment. Stopping the medication too early might result in a relapse of the infection. If your condition does not improve or worsens, inform your doctor.
