My 7yr old son has been on Intuniv for about a month and a half after being on Concerta 27mg. We decided to take him off Concerta for the summer and noticed that a month before being off of concerta he developed a tick (eye blinking). We were told that it will go away. Now it seems it is getting worse and he is complaining his eyes are dry and they hurt. Can anyone tell me if they have experienced this as well? It seems that it is really bothersome to him and the dr's just say it will go away and they don't think it is tourettes.
