Voriconazole has a distinctive adverse effect profile, with transient visual disturbances being particularly associated. Patients often report blurred vision, photophobia, or changes in color vision shortly after taking the dose, and these effects typically come on quickly and resolve within a short period, usually without lasting harm. The exact mechanism isn’t fully understood, but these visual symptoms are a well-recognized and characteristic reaction to this drug, not a sign of irreversible injury.

This stands out because other listed adverse effects are not unique to voriconazole. Nephrotoxicity is more typical of amphotericin B. QT prolongation can occur with several antifungals, and a rash can appear with many medications, but the pronounced, transient visual disturbances are the hallmark feature linked to voriconazole. Keeping an eye on liver function and drug interactions is also important with voriconazole, but the most classic and exam-worthy adverse effect is theseVisual disturbances.
