Varies: The correct dose of a medication is "enough." antihistamines are safe, so you don't have to worry as long as you stay in the recommendations. The 5mg tablet is great if it works, but he's old enough to tolerate the 10mg tablet if it doesn't.

Lower than adult.: Depends on the size: less than 90lbs, go with 5mg. If larger, the 10mg dose should be fine. Recently I have seen some very large 12 year olds.
