VFEND, also known by its generic name voriconazole, is a prescription antifungal medication used to treat a variety of serious fungal infections. It belongs to a class of drugs known as triazole antifungals and works by inhibiting the growth of fungi, thereby stopping the spread of infection. VFEND is commonly prescribed for infections such as invasive aspergillosis, candidemia in non-neutropenic patients, and certain fungal infections caused by Scedosporium apiospermum and Fusarium species, among others. It is available in several forms, including tablets, a powder for oral suspension, and an injectable solution, allowing for flexible administration options based on the patient's condition and needs. As with any medication, VFEND may cause side effects and its use should be closely monitored by a healthcare professional to ensure its efficacy and safety for the patient.
