Hi, I'm new here but was wondering if anyone is or has experienced the things I am with my DS. He is 7 years old and was diagnosed a little over a year ago with ADHD. The doctor started him on Vyvanse and at first it worked wonderfully. Then my son started to get very aggressive and angry. The doctor immediately switched him to Concerta 18mg. He was moved up to 27mg, then 36 and then they added intuniv. This worked great for about 6 months and when summer started it was like the meds worked well for maybe 4 hours then he would get more active ( I thought this was strange since Concerta is suppose to work for 12 hours) He also wanted to stay home all the time and would pitch a fit when we had to go somewhere. We called the doc over the summer and he said wait til his next appointment so school would be in and he could see what the teacher thought. She told me he would come in work hard and get his work completed the around 10;30 would get more active and inattentive. That he couldn't seem to focus. And in the afternoon he had a very hard time completing work. It took him a lot longer in afternoon verses morning. We went back to doc yesterday and they upped him to 54mg Concerta and said try that for a couple of days and see if it makes a difference. Has anyone else had this problem with Concerta? I've read that it takes about 20 mins to take affect after they take it, but I have a VERY hard time getting him to get ready and brush his teeth in the morning. Any thoughts? I don't know if he needs to switch meds or what. It's day 1 of the 54mg, so I hope to see a difference soon. I can't handle the freaking out all the time. Please give me your thoughts! Struggling!!!!!!!!!!!
