التداخل بين ليفونورجيستريل وإيثينيل إستراديول ولورلاتينيب

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.

Advise females of reproductive potential to use an effective non-hormonal method of contraception, since LORBRENA can render hormonal contraceptives ineffective, during treatment with LORBRENA and for at least 6 months after the final dose.
