Interactions between your drugs
ISOtretinoin momelotinib
Applies to: Claravis (isotretinoin), momelotinib
MONITOR: Coadministration of momelotinib may increase the plasma concentrations and effects of drugs that are substrates of CYP450 2B6. The proposed mechanism, based on in vitro data, is decreased drug clearance due to momelotinib-mediated inhibition of the CYP450 2B6 isoenzyme. However, clinical data are not available.
MANAGEMENT: Caution is advised if the momelotinib is administered with sensitive substrates of CYP450 2B6. Patients should be monitored for the development of adverse effects. Dosage adjustments as well as clinical and laboratory monitoring should be considered whenever momelotinib is added to or withdrawn from therapy with these drugs. Individual product labeling for the coadministered drug may also be consulted for specific guidance.
