I have a great grandson who was on Concerta but the Dr switched him to Focalin. He is now combative by kicking , mouthing , telling us to shut up etc. Is this a side affect or should he be put back on Concerta with a higher dose? We are legal guardians(in our 70s) and we have had him since 3 months old. He didn't act this bad before...Lots of hyperactivity on his part. He's only been put on medication during the summer. He is 8 yrs old and was an A student till now. He is taking 6mg of Melatonin and .01mg of Clonidine to get him to sleep...
