摘要
Cenobamate induces CYP3A4 and may lower systemic levonorgestrel, reducing the reliability of oral or emergency levonorgestrel contraception. The local effect of an intrauterine system is less affected.
用白話說明這項交互作用的意義
Cenobamate and Levonorgestrel 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; Levonorgestrel belongs to Endocrine.
為什麼會發生
CYP3A4 induction by cenobamate increases levonorgestrel metabolism.
處置方式
