In reply to Anyone heard of this interaction - Yasmin/Lamictal, posted by wildflower on January 31, 2005, at 9:40:04
wildflower-- i've heard a lot about interactions between anticonvulsants and oral contraceptives. i've heard more, though, about anticonvulsants reducing the effectiveness of birth control so that you need higher doses for protection or else a backup form of birth control. i know this is true of depakote and tegretol. funny, though, that when i was on depakote, they tested me all the time for pregnancy and recommended oral contraceptives because i guess depakote is very dangerous to the fetus and can cause birth defects.
i've heard of the interaction between lamictal and oral contraceptives, but i don't think the connection is as definite as with the other anticonvulsants; it's more speculative. the pharmacist mentioned it when i first started lamictal. actually the interaction is more like you described, at least according to what i've been told. the pharmacist has said that i may need a higher dose of contraceptives because lamictal may cause lower levels, not the other way around.
hope this helps.
