200mg is an ok dose, its what I'm on, I think some people go up to 300mg.... maybe higher for epilepsy
How fast did you increase your meds?
Are there any blisters, is it round?
Are your eyes and mouth ok?
Look at some of the pictures on the net and see if it looks the same.... dermatology is all about pictures!!!!
I think you should see your doctor if it gets worse or you are worried
