Drug Interaction Report

Consumer information for this interaction is not currently available.

GENERALLY AVOID: Coadministration with ceftobiprole may increase the plasma concentrations and the risk of adverse effects of drugs that are substrates of organic anion transporting polypeptide (OATP) 1B1 and/or OATP1B3. The proposed mechanism is decreased clearance due to ceftobiprole-mediated inhibition of OATP1B1 and/or OATP1B3.

MANAGEMENT: Concomitant use of ceftobiprole with drugs that are substrates of OATP1B1 and/or OATP1B3 is not recommended. Clinical and laboratory monitoring may be appropriate whenever ceftobiprole is added to or withdrawn from therapy with these drugs. Dosage adjustments may be considered if an interaction is suspected. Patients should be monitored for the development of adverse effects.
