Sintesi

Cenobamate induces CYP3A4 and may lower ethinyl estradiol and progestin levels. This can reduce contraceptive efficacy and risk unintended pregnancy, which matters because cenobamate is also used in women of childbearing potential.

Cosa significa questa interazione in parole semplici

Cenobamate and Desogestrel-ethinyl estradiol can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Cenobamate belongs to Central Nervous System; Desogestrel-ethinyl estradiol belongs to Endocrine.

Livello di evidenza: Moderate

Perché avviene

Cenobamate induces CYP3A4, increasing metabolism of ethinyl estradiol and etonogestrel.
