Hi there,
I'm on Lamictal....No rash. I DO know that this reaction to Lamictal is an important one to look out for. If you don't see improvment soon you get my run of the mill answer. "Get to the Dr. and get some answers".
Sometimes children don't communicate as well as adults about how they feel. It's hard for them to find the right words...You need to take charge, you are his ONLY advocate.
