"my son is 10 yrs old and has adhd. he has been on the patch for 4-5 months and the only side effects that he has is a redness where the patch was. other than that, its a miracle patch. his grades have doubled and the lowest grade he has gotten is one c. he wears it from 5:30am-3:30pm. i love it, it calms him down and he is happy to do his homework. i can only praise this medicine. some will give negative and positive reviews about the patch because it will effect everyone differently."
