"my 7 year old son started taking focalin xr 5 in december after i had him tested for what i was sure going to be asperges. turns out he was suffering from adhd...he is currently on 15 mg xr and i can honestly say for him it is a miracle drug. he went from not being able to read and barely writing his name to reading whole books...he also went from making 20&#039;s and 30&#039;s on spelling test to averaging 90, we even had 2 100&#039;s. he has lost some weight but right now is still average so it is not much of a concern."
