"my son is 7 years old and has been diagnosed with adhd and is using  daytrana 10mg which has been the best so far! after applying the patch, it takes a couple of hours for the medicine to start working. i noticed that if i place the patch on his hip, but closer to his butt it is more effective. (my doctor said that other parents had noticed that the placement of the patch makes a difference). at school he is able to control his impulses, focus and most importantly still be a 7 year old boy (not a zombie). the only downfalls to this medication is that he does not have an appetite (most of these meds cause this) &amp; the area where you place the patch can get red and itchy. i rotate where i place the patch and use baby oil to remove the adhesive"
