Certain CYP3A Substrates

Mitotane is a strong CYP3A inducer. Concomitant use of LYSODREN may decrease the concentrations of CYP3A substrates, which may reduce the efficacy of these substrates. Avoid the concomitant use of LYSODREN with certain CYP3A4 substrates where minimal concentration changes may lead to therapeutic failure. If concomitant use cannot be avoided, increase the CYP3A substrate dosage in accordance with approved product labeling.


When administering coumarin-type anticoagulants to patients receiving LYSODREN, monitor coagulation tests and adjust the anticoagulant dose as needed.
