Hi rwb1,
Welcome to the forum! I've never been on zonegran but the rash you are describing sounds like what happened to me when I was put on lamictal I broke out with red spots all over my skin, and then the red spots began to itch. I had to see a dermatologist (skin specialist) who did a biopsy on me and found I was allergic to the drug. I was then given perscription steroid cream to put on my skin to stop the itching. My advice to you is to call your pharmacist and get the detail on the rash zonegran can cause and then see a dermatologist a.s.a.p. I wish you the best of luck and May God Bless You!
