医界专家:

其他避孕建议：共同给予某些抗惊厥药如卡马西平，eslicarbazepine、奥卡西平，苯巴比妥、苯妥英、和扑米酮可能会降低效的避孕激素。已经有众多的情况报告的经异常(例如，突破性出血、经闭、不规则月)和意外怀孕的发生在妇女接受了口服避孕药具的用抗惊厥药。发病率的月经不规则与此相关的组合已经报道尽可能高达65%，在一些研究。相互作用的源自加速清关的激素避孕，以及减少等离子浓度的未结合(活动)的激素，由于感应的肝CYP450酶的活性和激素结合的球蛋白能力通过一些抗惊厥药。药物动力学研究发现，通常推荐剂量的卡马西平，奥卡西平，苯巴比妥，并苯妥英能单独地减少乙炔雌二醇和左炔诺孕酮的系统暴露(AUC)通过的第三个或更多。 Eslicarbazepine酸乙酯1200毫克每天一次，为期2周的减少意味着哥伦比亚联合自卫军的单剂量乙炔雌二醇(30微克)和左炔诺孕酮(150微克)32%和24%，同时分别eslicarbazepine800毫克每天一次下降的意思是AUCs25%和11%。

管理：妇女使用激素避孕药，应被告知危险的突破性出血和意外怀孕期间，伴随治疗与酶诱导的抗惊厥药。替代或额外的方法控制生育期间应使用和至少两个星期之后的短期的和4个星期之后长期(大于4周)的抗惊厥疗法治疗。如果一个组合的口服避孕药是使用，一方案含有至少50微克的乙炔雌二醇每天或相当于应当予以考虑。虽然突破性出血不一定是指示性的低乙炔雌二醇的血清水平或增加的风险的排卵，一些临床医生建议的妇女经验的突破时出血酶诱导疗法可能规定增加剂量乙炔雌二醇上述的50微克的日常通过合并多个制剂的避孕药丸，如果有必要的。对于紧急避孕者使用的一种肝酶诱导剂在过去4周，非紧急荷尔蒙避孕药具(例如，铜宫内装置)被认为是可取的。如果这是不可能的，有些当局的建议通常剂量的左炔诺孕酮(1.5毫克)应增加一倍至3毫克，并采取作为一个单剂量尽快(在72小时内未受保护的性交). 然而，目前尚无数据可证明效力、合规性或副作用的这种方案。对于妇女与依托孕烯皮下植入物，另外一个障碍的方法是建议在伴随使用和28天之后停止的肝酶诱导的药物。它建议删除植入物，并规定一个nonhormonal方法在妇女需要长期治疗肝酶诱导的药物。没有预防措施或提出建议，供妇女使用激素释放宫内节育系统，但是显着的相互作用与这些系统被认为是不太可能由于他们的地方行动。注射孕只避孕药具也被认为是不受酶诱导的药物。
