Can epilepsy medication affect the morning after pill?

Yes, certain epilepsy medications can affect the efficacy of the morning-after pill. Some antiepileptic drugs, particularly enzyme inducers like phenytoin and carbamazepine, may reduce the effectiveness of hormonal contraceptives, including emergency contraception. It's important for individuals on such medications to consult with their healthcare provider about potential interactions and alternative contraceptive options to ensure proper protection.
