My folks gave me antihistamines( benadryl) ONCE as a child....only ONCE...I dont remember but they told me I stayed up over 24 hours was happy and playing away and go go go go but never tired and they couldnt keep me in bed.....rough couple of days for them I am sure
You might try a different DR. . Stratterra has a pretty broad side effect profile itself if you read the insert. Many of them are the exact same ones as ritalin and Stratterra being a new drug they really don't know what it will do in 15 years. I wonder why they would think a child young for his grade had developmental problems. I was old for my grade and the school still called my problems "developmental" and tried to put me in "special" classes. honestly, I am sure it was the ADD. I didn't follow directions well because I really really really didnt want to do the tasks asked I am sure( not that I recall now). For me doing boring tasks umedicated is like having teeth filled w/o novacaine... it causes me real distress. I don't know a lot about autism but, I don't think it's "mild" even in "mild" forms. My limited understanding is even in mild forms like Aspurburgers it is pronounced.
I changed my diet radically when diagnosed...My Dr insisted it would be very therapuetic for adhd/anxiety
