Can Lamitrin weaken the effect of Evra patches?

Lamitrin does not affect the contraceptive effectiveness of Evra. Nevertheless, you should always inform the gynecologist about all other medicines used. Conversely, there is an interaction that should be taken into account: The oestrogens in Evra may weaken the anticonvulsant effect of lamotrigine (the active ingredient in Lamitrin). This may result in worsening seizure control and lamotrigine dosage adjustment may be necessary. Therefore, I encourage you to contact your doctor.
