Hi Fuzzybear: Yes... I had never even heard of Lamictal rash & my didn't mention it when he prescribed it. I just developed this rash on my chest & forearms about 6 weeks into taking it, & decided I should have it looked at. So I went my GP & he sent me upstairs immediately to see a dermatologist. Since I had it looked at right away, it was able to be cleared up quickly. But from what my dermatologist told me, had I waited, it could have been serious!
