Probably you should hold it and see your family dr as well as letting your pdoc know. Just b/c you have rash doesn't mean they'll stop it forever; there is actually a lot of evidence that you can safely re-start it very slowly after getting The Rash.

I had The Rash. It was raised, hot, and burned like severe sunburn. It did slightly resemble acne. One reason you should get it checked it that the closer to the face the more of an issue The Rash is. It's probably nothing, very few rashes are, but you should be checked. When I got it I had this little patch of itchy bumps on the side of my face. I'd been on lamictal eight or 10 weeks and had been on it before so I didn't think at all before I took another dose. I woke up with rash all over my face and by mid-afternoon my eye was swollen shut, my lips were affected and so was most of my face and neck. If I'd skipped a dose and gone to the dr it might never have gotten so bad.
