Sooper,
I too was terrified of the rash before taking Lamictal, but I never got it. I was on Lamictal for almost 2 years in the past and stopped because it was not working well for me anymore snd switched to another mood stabilizer. There are tons of people on HW who are currently taking it, or have taken it in the past that will have similar situations. Of course as with any medication, Lamictal has risks, but like you said the % of getting the rash is low. And from someone who has taken it for almost 2 years and at 300mg at the highest dose, I am telling you it will be okay. Plus yhr chances of developing the rash shows up within the 1st few weeks of the initial dose.
Hang in there, and know we are here for you.
