In a woman with bipolar disorder with a menstrual component would lamotrigine itself worsen the condition given that it interacts with prescribed estrogen?
Does lamotrigine interfere with baseline estradiol levels in a woman who is not prescribed estrogen otherwise?
Answer from: at Community Practice
Very unlikely. Estrogen can cause a lowering of the Lamictal serum levels and not vice versa. So, if a patient on Lamictal is put on an estrogen product, there may be a need to increase the dose of Lamictal.
