VFEND- voriconazole injection, powder, lyophilized, for solution
VFEND- voriconazole powder, for suspension
VFEND is indicated in adults and pediatric patients (2 years of age and older) for the treatment of invasive aspergillosis (IA). In clinical trials, the majority of isolates recovered were Aspergillus fumigatus. There was a small number of cases of culture-proven disease due to species of Aspergillus other than A. fumigatus [see Clinical Studies (14.1, 14.5) and Microbiology (12.4)].
VFEND is indicated in adults and pediatric patients (2 years of age and older) for the treatment of candidemia in non-neutropenic patients and the following Candida infections: disseminated infections in skin and infections in abdomen, kidney, bladder wall, and wounds [see Clinical Studies (14.2, 14.5) and Microbiology (12.4)].
VFEND is indicated in adults and pediatric patients (2 years of age and older) for the treatment of esophageal candidiasis (EC) in adults and pediatric patients 2 years of age and older [see Clinical Studies (14.3, 14.5) and Microbiology (12.4)].
VFEND is indicated for the treatment of serious fungal infections caused by Scedosporium apiospermum (asexual form of Pseudallescheria boydii) and Fusarium spp. including Fusarium solani , in adults and pediatric patients (2 years of age and older) intolerant of, or refractory to, other therapy [see Clinical Studies (14.4) and Microbiology (12.4)].
Specimens for fungal culture and other relevant laboratory studies (including histopathology) should be obtained prior to therapy to isolate and identify causative organism(s). Therapy may be instituted before the results of the cultures and other laboratory studies are known. However, once these results become available, antifungal therapy should be adjusted accordingly.
Administer VFEND Tablets or Oral Suspension at least one hour before or after a meal.
VFEND I.V. for Injection requires reconstitution to 10 mg/mL and subsequent dilution to 5 mg/mL or less prior to administration as an infusion, at a maximum rate of 3 mg/kg per hour over 1 to 3 hours.
Administer diluted VFEND I.V. by intravenous infusion over 1 to 3 hours only. Do not administer as an IV bolus injection.
Blood products and concentrated electrolytes
VFEND I.V. must not be infused concomitantly with any blood product or short-term infusion of concentrated electrolytes, even if the two infusions are running in separate intravenous lines (or cannulas). Electrolyte disturbances such as hypokalemia, hypomagnesemia and hypocalcemia should be corrected prior to initiation of and during VFEND therapy [see Warnings and Precautions (5.10)].
Intravenous solutions containing (non-concentrated) electrolytes
VFEND I.V. can be infused at the same time as other intravenous solutions containing (non-concentrated) electrolytes, but must be infused through a separate line.
Total parenteral nutrition (TPN)
VFEND I.V. can be infused at the same time as total parenteral nutrition, but must be infused in a separate line. If infused through a multiple-lumen catheter, TPN needs to be administered using a different port from the one used for VFEND I.V.
Invasive aspergillosis and serious fungal infections due to Fusarium spp. and Scedosporium apiospermum
See Table 1. Therapy must be initiated with the specified loading dose regimen of intravenous VFEND on Day 1 followed by the recommended maintenance dose (RMD) regimen. Intravenous treatment should be continued for at least 7 days. Once the patient has clinically improved and can tolerate medication given by mouth, the oral tablet form or oral suspension form of VFEND may be utilized. The recommended oral maintenance dose of 200 mg achieves a voriconazole exposure similar to 3 mg/kg intravenously; a 300 mg oral dose achieves an exposure similar to 4 mg/kg intravenously [see Clinical Pharmacology (12.3)].
Candidemia in non-neutropenic patients and other deep tissue Candida infections
See Table 1. Patients should be treated for at least 14 days following resolution of symptoms or following last positive culture, whichever is longer.
See Table 1. Patients should be treated for a minimum of 14 days and for at least 7 days following resolution of symptoms.
|Infection||Loading Dose||Maintenance Dose *, †|
|Intravenous infusion||Intravenous infusion||Oral ‡|
|Invasive Aspergillosis §||6 mg/kg every 12 hours for the first 24 hours||4 mg/kg every 12 hours||200 mg every 12 hours|
|Candidemia in nonneutropenic patients and other deep tissue Candida infections||6 mg/kg every 12 hours for the first 24 hours||3–4 mg/kg every 12 hours ¶||200 mg every 12 hours|
|Esophageal Candidiasis||Not Evaluated #||Not Evaluated #||200 mg every 12 hours|
|Scedosporiosis and Fusariosis||6 mg/kg every 12 hours for the first 24 hours||4 mg/kg every 12 hours||200 mg every 12 hours|
Method for Adjusting the Dosing Regimen in Adults
If patient’s response is inadequate, the oral maintenance dose may be increased from 200 mg every 12 hours (similar to 3 mg/kg intravenously every 12 hours) to 300 mg every 12 hours (similar to 4 mg/kg intravenously every 12 hours). For adult patients weighing less than 40 kg, the oral maintenance dose may be increased from 100 mg every 12 hours to 150 mg every 12 hours. If patient is unable to tolerate 300 mg orally every 12 hours, reduce the oral maintenance dose by 50 mg steps to a minimum of 200 mg every 12 hours (or to 100 mg every 12 hours for adult patients weighing less than 40 kg).
If patient is unable to tolerate 4 mg/kg intravenously every 12 hours, reduce the intravenous maintenance dose to 3 mg/kg every 12 hours.
