Deb9 – thank you! we did try vyvanse at first and he was allergic – broke out in a rash on his back and chest. So we switched to concerta. The pediatrician recommended increasing intuniv for now and he is low weight. if we can get his weight up we can increase the dose of concerta. I wonder if adderrall has the same “ingredients” as vyvanse or if its different so not to cause an allergic reaction. thank you! I will definitely ask the pediatrician about this and maybe a med switch is needed.
