Note on Lamictal Interaction with Estriodol

I had forgotten that birth control pills containing Estriodol can reduce blood plasma levels of Lamictal by 40 to 60% in some cases (see Drugs.com for drug interactions with Lamictal.) This means that we may have to increase Caroline's Lamictal in order for it to still be effective while taking hormones to clear up her skin.  She is supposed to get a Lamictal level drawn this week so I guess we will see what it indicates, as well as a Trileptal and Lithium level.  Another mom I know through CABF whose daughter is taking estrogen says that the topical cream interferes less with the Lamictal than the pill form.  Just wanted to share this information with you!
