Just wondering...........I realize that concerta is dosed according to weight, but difficult child has been doing so well on it for a long time. We did at one point try to up the dose a little bit, but found that it made her more aggressive, so we put her back on 36 mg. The last few weeks, we have been seeing alot of her old behaviors starting to surface again. I'm really leery of upping the dosage again because of what happened last time. The school seems to think that maybe she has hit a plateau on her medications. Is this something that happens on concerta? We first tried her on strattera, but she could only tolerate the lowest dose on that as well. difficult child says she tries to be good, but she can't do it most of the time. It feels like we're back to square one again. Any suggestions?
