QT Prolongation SEZABY may prolong the QT interval [see Clinical Pharmacology (12.2)] .

• Concomitant use of strong CYP3A4 inducers: Increase quetiapine dose up to 5 fold when used in combination with a chronic treatment (more than 7-14 days) of potent CYP3A4 inducers (e.g., phenytoin, rifampin, St.

• Discontinuation of strong CYP3A4 inducers: Reduce quetiapine dose by 5‑fold within 7-14 days of discontinuation of CYP3A4 inducers ( 2.6 , 7.1 , 12.3 )

Quetiapine exposure is increased by the prototype CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, indinavir, ritonavir, nefazodone, etc.) and decreased by the prototype of CYP3A4 inducers (e.g., phenytoin, carbamazepine, rifampin, avasimibe, St.
