Ok guys, help me out here. difficult child started on 5mg/2x a day of ritalin almost two weeks ago, after a few days of no change the plan was to up it to 10mg/2x a day. On day 5 of the medications difficult child had a spectacular morning at school, refused afternoon medications and was aggressive and acting out. Tuesday took medications in morning and afternoon and was awesome. Wed. took it in the morning and was out of control. Thursday, also out of control. Fri, ok. Didn't give it to him over the weekend. I'm worried about giving it to him tomorrow- he was both awesome and alternately out of his mind at different points. Do I attribute the good times to the medications and say the bad times were old issues coming through or do I say-this kid has problems that need resolving before this medication can be effective consistently. The psychiatrist and I have been discussing bipolar for months and know that stims can cause mania. What does this sound like to you?
