I am a nurse in a school system in PA. Your nurse functions under the same window that I must – state law, no choice. Why does your grandson take his medication at 8 am at school? It takes at least 30 minutes to start taking effect, so your grandson is in class for at least 30 minutes without his medication. I have an ADD son myself and always gave his medication at home so it was in his system before he even got to school. If he gets a lunch time dose to boost his afternoon attention, I get that, but never understand why am doses are not given at home.
