Take voriconazole exactly as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. To do so may increase the chance of side effects.
Voriconazole comes with a patient information leaflet. Read and follow these instructions carefully. Ask your doctor or pharmacist if you have any questions.
It is best to take voriconazole at least 1 hour before or 1 hour after a meal.
Shake the oral liquid well before each use. Use the oral dispenser that comes with the package to measure the dose. Rinse the oral dispenser with water after each use.
Do not mix the oral liquid with any other medicine, liquid, or syrup.
Keep using voriconazole for the full treatment time, even if you feel better after the first few doses. Your infection may not clear up if you stop using the medicine too soon.
