التداخل بين إسليكاربازيبين 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.

Hormonal Contraceptives: APTIOM may decrease the effectiveness of hormonal contraceptives.

Oral Contraceptives Because concomitant use of APTIOM and ethinylestradiol and levonorgestrel is associated with lower plasma levels of these hormones, females of reproductive potential should use additional or alternative non-hormonal birth control.
