Zortress Interactions


Avoid live vaccines, standard doses of cyclosporine. Increased risk of angioedema with ACE-inhibitors. Potentiated by CYP3A4 and/or P-glycoprotein inhibitors; avoid strong inhibitors (eg, ketoconazole, itraconazole, voriconazole, clarithromycin, telithromycin, ritonavir, boceprevir, telaprevir, grapefruit juice, digoxin); monitor and adjust dose with moderate inhibitors (eg, erythromycin, fluconazole, nicardipine, diltiazem, nelfinavir, indinavir, amprenavir), or CYP3A4 and P-glycoprotein substrate (eg, verapamil). Potentiates octreotide. Antagonized by CYP3A4 inducers (eg, carbamazepine, phenobarbital, phenytoin, efavirenz, nevirapine, St. John's Wort); avoid strong inducers (eg, rifampin, rifabutin). Avoid simvastatin, lovastatin; monitor if used with atorvastatin or pravastatin. Caution with other nephrotoxic drugs, CYP3A4 or CYP2D6 substrates with a narrow therapeutic index.
