Nancy, The only mention we could find about the burning was in Duvoisin's book. When we called this to the attention of the neuro that we were seeing then, he called a Dr. Jake Sage who, i believe, is associated with Dr Duvoisin. He said that they had some experience with the burning sensation. He recommended niacinamide. This had no benefit. Now that she is taking Clozaril, the burning sensation is erratic, and at times more severe than before. However, there are times when she is free of it. Good luck! Irving Williams - via BulkRate 2.0
