摘要
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.
用白話說明這項交互作用的意義
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.

為什麼會發生
