What the FDA labels say
From the Emtricitabine, rilpivirine, and tenofovir (COMPLERA) label · effective 2025-07-16
Concomitant use of COMPLERA with drugs with a known risk to prolong the QTc interval of the electrocardiogram may increase the risk of Torsade de Pointes.
In healthy subjects, 75 mg once daily and 300 mg once daily doses of RPV (3 times and 12 times the dose in COMPLERA) have been shown to prolong the QTc interval of the electrocardiogram.
QT Prolonging Drugs There is limited information available on the potential for a pharmacodynamic interaction between RPV and drugs that prolong the QTc interval of the electrocardiogram.
In a study of healthy subjects, 75 mg once daily and 300 mg once daily doses of RPV (3 times and 12 times the dose in COMPLERA) have been shown to prolong the QTc interval of the electrocardiogram [see Warnings and Precautions (5.7) and Clinical Pharmacology (12.2) ] .
