Abstract
Epilepsy is a chronic condition that is usually managed through antiepileptic drugs (AEDs). An estimated 1 million girls and women in the USA have the disorder. The stigma associated with epilepsy can impact their quality of life, including their romantic and sexual relationships and reproductive decisions. Women with epilepsy (WWE) can use contraception safely and successfully, though difficulties understanding confusing drug-drug interactions and navigating complex health systems can make obtaining appropriate contraceptive care challenging. Nonhormonal methods pose no unique issues for WWE. However, there is potential for bidirectional interactions between AEDs and hormonal contraceptives. AEDs that induce hepatic cytochrome P450 enzymes can reduce hormonal contraceptive effectiveness. Optimal contraceptive methods for women taking enzyme-inducing AEDS include any intrauterine device (IUD) or depot medroxyprogesterone acetate (DMPA, 150 mg). Recommendations for women taking no AED or non-inducing AEDs mirror those for their healthy peers. Estrogenic components of combined methods rapidly lead to large reductions in lamotrigine (LTG) levels. When combined hormonal methods are used, LTG dose adjustment is necessary in consultation with a neurologist to maintain seizure control. Accurate contraceptive guidance promotes both the reproductive and neurological health of WWE.
