I run a daycare and one of my kids is also a difficult child. He has been on 27mgs of concerta and was doing well with it. He is ADHD and ODD. A bit more argumentative and irritable than my difficult child but otherwise very similar. His mum felt that the medications weren't working as well and so the doctor upped him to the next dosage (32mgs? not sure what it is). Since then I have found him sullen and not as active or EXTREMELY irritable. He goes to a behavioral school but has been pretty successful there in the past. He has been there a week now and has cussed out his teacher twice and tried to hit her yesterday. This is not normal for him at all. I know when we started our difficult child back on his medications last week, the aggression and moodiness started up again. I am pretty sure that it is a side effect of the medication. Does this sound to you guys like the medications might be to high for him? He has always done well with the concerta so it doesn't seem to be the medication itself. His mum is lost at what to do. The school is calling her constantly and she's not sure what to do.
