Vfend (Voriconazole)

The most common side effects associated with voriconazole include transient visual disturbances, fever, rash, vomiting, nausea, diarrhea, headache, sepsis, peripheral edema, abdominal pain, and respiratory disorder. Unlike most adverse effects, which are similar to other azole antifungal agents, visual disturbances (such as blurred vision or increased sensitivity to light) are unique to voriconazole. These have been reported by more than 30% of patients in clinical trials. They generally occur approximately one-half hour after administration, and last approximately 30 minutes. In some patients they may go away after continued use. Studies have shown that there is no damage to the eye or long-term effect on vision. However, patients taking voriconazole should be advised against driving at night or other potentially hazardous tasks. Though rare, there have been cases of serious hepatic reactions during treatment with voriconazole (a class effect of azole antifungal agents). Liver function tests should be evaluated at the start of and during the course of therapy. This medication may also cause your skin to peel easily. It is best to apply lotion and/or coconut oil to help with this side effect.
