التداخل بين أرمودافينيل وليفونورجيستريل وإيثينيل إستراديول

Enzyme inducers (e.g., CYP3A4) : May decrease the effectiveness of TYBLUME or increase breakthrough bleeding.

Metabolic Enzyme Inducers Clinical effect Concomitant use of CHCs with metabolic enzyme inducers may decrease the plasma concentrations of the estrogen and/or progestin component of CHCs [see Clinical Pharmacology (12.3) ] .

Counsel patients to use a back-up or alternative method of contraception when enzyme inducers are used with TYBLUME.

Prevention or management Counsel females to use an alternative method of contraception or a backup method when enzyme inducers are used with CHCs.

Continue backup contraception for 28 days after discontinuing the enzyme inducer to maintain contraceptive reliability.

Effects of NUVIGIL on CYP3A4/5 Substrates The clearance of drugs that are substrates for CYP3A4/5 (e.g., steroidal contraceptives, cyclosporine, midazolam, and triazolam) may be increased by NUVIGIL via induction of metabolic enzymes, which results in lower systemic exposure.

The effectiveness of steroidal contraceptives may be reduced when used with NUVIGIL and for one month after discontinuation of therapy.

Alternative or concomitant methods of contraception are recommended for patients taking steroidal contraceptives (e.g., ethinyl estradiol) when treated concomitantly with NUVIGIL and for one month after discontinuation of NUVIGIL treatment.

Steroidal contraceptives (e.g., ethinyl estradiol): use alternative or concomitant methods of contraception while taking NUVIGIL and for one month after discontinuation of NUVIGIL treatment.
