Résumé
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.
Ce que signifie cette interaction, en termes simples
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.
Pourquoi elle survient
Mechanism unclear; acitretin may reduce the contraceptive efficacy of low-dose progestins.
Conduite à tenir
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.
