Useful For
Monitoring trough levels of voriconazole is suggested for:
-Individuals with reduced liver function
-Individuals with cytochrome P450 (CYP) 2C19 alterations associated with poor metabolic function
-Patients taking other medications that affect CYP2C19 activity
-Patients experiencing potential toxicity
Monitoring trough levels may be reasonable in patients who are not responding optimally or have drug interactions that may decrease voriconazole levels or to ensure adequate oral absorption
