概要
Lesinurad can lower systemic exposure to norethisterone, which may reduce contraceptive reliability and raise the risk of unintended pregnancy. Breakthrough bleeding or loss of cycle control may also occur.
この相互作用をわかりやすく説明すると
Lesinurad and Norethisterone 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.
Lesinurad belongs to Genitourinary; Norethisterone belongs to Endocrine.
なぜ起こるのか
Lesinurad is a weak CYP3A inducer that may increase the metabolism of norethisterone.
対処法
Do not rely on norethisterone alone for contraception; add a nonhormonal barrier method during lesinurad therapy and for a period after stopping. Consider an alternative urate-lowering agent if effective hormonal contraception is essential.
