摘要
Acitretin has been reported to interfere with progestin-only contraceptives, such as minipills, reducing their effectiveness. Since acitretin is highly teratogenic, any contraceptive failure is serious. Labeling advises against progestin-only pills in this setting.
用白話說明這項交互作用的意義
Acitretin and Norethindrone are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
為什麼會發生
Mechanism unclear; acitretin may reduce the contraceptive efficacy of low-dose progestins.
處置方式
Do not rely on norethindrone-only contraception during acitretin therapy. Use two reliable contraceptive methods, such as a combined hormonal method plus a barrier method, as advised by labeling.
