Voriconazole
Summary
Voriconazole is used to treat serious fungal infections such as invasive aspergillosis (a lung infection), esophageal candidiasis (a yeast infection of the food pipe), and candidemia (a yeast infection in the bloodstream).
Voriconazole works by slowing down the growth of fungi, which are tiny organisms like yeast and mold. By inhibiting the growth of these fungi, it helps to treat serious infections.
Voriconazole can be taken as a pill or a liquid medicine. It's usually taken twice a day, every 12 hours, on an empty stomach. This means you should take it at least one hour before or two hours after eating.
Common side effects of voriconazole include blurry vision, fever, nausea, rash, vomiting, and chills. Less common but reported side effects include headaches, elevated liver enzymes, fast heart rate, and hallucinations. Serious side effects can include liver damage, serious heart problems, and allergic reactions.
Individuals with known hypersensitivity to voriconazole or other triazole antifungals should avoid this medication. Caution is also advised in patients with a history of liver disease or those taking medications that may interact adversely with voriconazole.
