Relevance: 15.09.2022 Reviewer: Shkutko P.M., M.D., in

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Consumer:

Rofecoxib is no longer on the market in the US. Do not take rofecoxib with any other medication.

Professional:

ADJUST DOSE: The coadministration of rifampin and rofecoxib may result in decreased plasma concentrations of the latter. According to the manufacturer, rifampin 600 mg daily produced an approximately 50% decrease in plasma rofecoxib concentrations. The mechanism is accelerated clearance of rofecoxib due to enhanced CYP450 3A4 enzymatic activity by rifampin.

MANAGEMENT: A starting dosage of rofecoxib 25 mg once daily should be considered for the treatment of osteoarthritis in patients receiving rifampin therapy. Monitoring for altered efficacy and safety is recommended.
