Ever since I bumped up my Lamictal to 150mg twice daily 6 months ago, I am so itchy dry skin particularly on my legs I have scabs on my legs and feet. I also got on antipsychotics about this time. It started with risperdone, I thought the itchiness came from the risperdone so I was switched to ability and the itchiness didn't change. I've been on Lamictal for 1 year along with buspar. Abilify/Risperdone for 6 months. There has been no rash.
