I agree with KD, I was on Lamictal and had the beginnings of a rash on both legs and they had to take me off of it due to the reasons you are speaking of and what the information that KD found.

My rash was not as severe as what you described though I would definatly seek medical attention right away and make sure to let them know you are taking Lamictal. I hope you can get this taken care of and let us know what you find out.

Oh, I found out that the rash from Lamictal may not show up right away and can at times show up to 90 days after beginning Lamictal treatment. My rash did not appear until I had already been taking the medication for over 60 days.

Best Wishes.
