There are different classes of meds for attention: sounds like your child might be on a stimulant med (like Ritalin or several others). For some kids this increases irritability or moodiness, causes sleeplessness or weight loss, etc.
There exist other meds that don't have quite the same potency, but also don't have those side effects: Strattera is one, but there are others too. You might ask your prescriber about trying a non-stimulant ADHD med and seeing if you can get a better balance in place.
