Indications for VFEND:

Invasive aspergillosis. Nonneutropenic candidemia. Candida infections in abdomen, kidney, bladder wall, wounds, or skin (disseminated). Esophageal candidiasis. Serious infections caused by Scedosporium apiospermum and Fusarium species in patients intolerant of, or refractory to, other therapy.


See full labeling. Infuse IV over 1–2hrs; max rate 3mg/kg per hour. Aspergillosis, Scedosporium and Fusarium: initially 6mg/kg IV every 12hrs for 2 doses, then 4mg/kg every 12hrs; continue for at least 7 days. Candidemia, other deep tissue candida infections: initially 6mg/kg IV every 12hrs for 2 doses, then 3–4mg/kg every 12hrs; treat for at least 14 days after symptoms resolve or following last positive culture, whichever is longer. Both: switch to oral form when tolerated; give 1hr before or after meals. Oral forms (<40kg): 100mg every 12hrs; may increase to 150mg every 12hrs if inadequate response; (≥40kg): 200mg every 12hrs; may increase to 300mg every 12hrs if inadequate response. Esophageal candidiasis: oral forms (<40kg): 100mg every 12hrs; (≥40kg): 200mg every 12hrs; treat for a minimum 14 days, and for at least 7 days after symptoms resolve. Concomitant efavirenz: increase voriconazole dose to 400mg every 12hrs and decrease efavirenz dose to 300mg every 24hrs. Concomitant phenytoin: increase voriconazole dose. Hepatic impairment (mild-to-moderate): reduce maintenance dose by ½; (severe): see full labeling. Renal impairment (CrCl <50mL/min): oral forms preferred. Duration of therapy, and for dose adjustments: see full labeling.


<2yrs: not recommended. See full labeling. 2–14yrs (<50kg): Aspergillosis, Scedosporium and Fusarium, Candidemia, other deep tissue candida infections: initially 9mg/kg IV every 12hrs for 2 doses, then 8mg/kg IV every 12hrs. Esophageal candidiasis: 4mg/kg IV every 12hrs. Oral forms: 9mg/kg every 12hrs (at max 350mg every 12hrs). ≥12yrs (≥50kg): use adult regimen. Hepatic or renal impairment: monitor closely.

Correct electrolyte disturbances before and during treatment. Monitor AST/ALT levels and bilirubin at baseline, at least weekly for the first month, then monthly thereafter; discontinue if LFTs become markedly elevated. Monitor renal function. Proarrhythmic conditions (eg, QT prolongation, arrhythmias). Monitor visual function (including acuity, field, color perception) if used >28 days. Risk factors for acute pancreatitis (eg, recent chemotherapy, HSCT); monitor. Discontinue if severe cutaneous reactions, squamous cell carcinoma, melanoma, or skeletal adverse events occur. Avoid direct sunlight. Tabs: galactose intolerance. Embryo-fetal toxicity. Advise females of reproductive potential to use effective contraception during therapy. Pregnancy. Nursing mothers.

Potentiates, and potentiated by oral contraceptives; monitor. Antagonized by phenobarbital, phenytoin, possibly delavirdine, efavirenz 300mg every 24hrs, other CYP3A4 inducers. Concomitant everolimus, fluconazole: not recommended. Avoid concomitant low-dose ritonavir (100mg every 12hrs).
