About a year ago there was a study going on for children with ADHD who were already taking medication to treat their symptoms. The study involved taking a blood pressure medication along with their current medication. Is INTUNIV that medication? My 11 yr old son is taking Concerta 27mg to treat his ADHD and I'm wondering if it would benefit him to take INTUNIV as well. I also have an 8 yr old son with ADD who has started taking INTUNIV because stimulant medications are too much for him and make his ADD worse. However, my 11 yr old son has benefited greatly from the stimulant which also makes him tired. It's amazing that a stimulant can make a person tired which was confirmation that he has ADHD and not just ADD.
