Lamictal is started at 50 mg and increased by 50 every two weeks until therapeutic dose is reached. I think the therapeutic dose is supposed to be 250-350 mg. It has to be administered slowly because it can cause a dangerous rash. (Susceptibility for the rash is higher during the first 6 mths.) I've been on all sorts of doses over last 10 yrs and hasn't done a thing for me.

Wait out the skin-crawling. If it doesn't get better within 4-5 days give your Doc a call I'd say.
