My son's doctor perscribed dexedrine for my son's hyper and agresive behavior, today was the first day, it made him cry for the first hour and it also made him irratiable, his doctor called to see how he was doing and i told him about how he seems irratiable, he said that it is common for the first three days then i should start seeing good things, but if he still is acting irratiable after three days i should get him off. I would like to know if anybody has tried this med on thier child if so how did it affect him/her and if they had any side effects i am just curious thank you. Kathy
