CONTRACEPTIVES AND MODAFINIL
Modafinil slightly reduced the levels of ethinylestradiol taken as part of a combined
hormonal contraceptive. Emergency hormonal contraceptives and progestogen-only
implants may also be less effective if taken with modafinil.
These small changes may be sufficient to cause the failure of combined hormonal contraceptives in rare cases. For additional advice on the use of enzyme inducers, such as modafinil, and contraceptives, see contraceptives. It is also recommended that additional or alternative methods should be continued for up to 2 cycles after stopping modafinil.
