my five year old son has been on meds for adhd since about 2 years ago. In the past two months i have had to have his med changed he was on strattera and doing okay. He is now on dexedrine and has starting getting aggresive at school and very rude and mouthy at home. The school suggested he gets counseling but i still dont know what to do about the medication. Any one know anything about the different medications?? Any ideas?
