Isavuconazonium Disease Interactions

Isavuconazonium shortened the QTc interval in a concentration-related manner. This drug is contraindicated in patients with familial short QT syndrome.

The use of isavuconazonium has been associated with hepatic adverse reactions (e.g., elevations in ALT, AST, alkaline phosphatase, total bilirubin). Cases of more severe hepatic reactions (including hepatitis, cholestasis, hepatic failure including death) have been reported during therapy in patients with serious underlying medical conditions (e.g., hematologic malignancy). Liver-related laboratory tests should be evaluated at the start and during therapy. Isavuconazonium has not been studied in patients with severe liver dysfunction (Child-Pugh C) and should be used in these patients only when the benefits outweigh the risk. Clinical monitoring for drug-related side effects is recommended when treating patients with severe liver dysfunction.
