{"Based on the genotype result, this patient is predicted to be a likely CYP2C19 poor metabolizer, and higher than normal trough concentrations of voriconazole are likely and may increase the probability of adverse reactions. Choose an alternative agent that is not dependent on CYP2C19 metabolism as primary therapy instead of voriconazole such as isavuconazole, liposomal amphotericin B or posaconazole. Selection of an alternative agent should be based upon other clinical factors such as drug interactions, hepatic and/or renal function, suspected or documented fungal species, site of infection, and comorbidities. Where voriconazole is strongly indicated for treatment of an invasive mycosis, administration of a lower dosage with meticulous therapeutic drug monitoring may be feasible. Please consult a clinical pharmacist for more information."}
