A doctor should be consulted to address the issue of joint drug administration.

Consumer information for this interaction is not currently available.GENERALLY AVOID: Coadministration with inducers of the P-glycoprotein (P-gp) efflux transporter and/or the uridine diphosphate glucuronosyltransferase (UGT) enzymes may decrease the plasma concentrations of letermovir according to the product labeling. Because letermovir is a substrate of P-gp and UGT 1A1 and 1A3, induction of the efflux transporter and metabolic enzymes may theoretically increase the clearance of letermovir. Concomitant use of rifampin initially resulted in a clinically insignificant increase in letermovir plasma concentrations (due to inhibition of organic anion transporting polypeptide [OATP] 1B1/3 and/or P-gp), followed by clinically significant decreases in letermovir plasma concentrations with continued rifampin coadministration (due to induction of P-gp/UGT). MANAGEMENT: Letermovir product labeling recommends avoiding concomitant use with inducers of P-gp and/or UGT. References Cerner Multum, Inc. "UK Summary of Product Characteristics."
