Can I give my 9 yr old son Aleve? He weighs over 110 lbs and is almost 5 ft tall. He is a big athlete and frequently has lingering muscle injuries or inflammation that I know will be helped by this over the counter medicine. Can you tell me the correct dosage for him? I know the label on the bottle says do not use under 12 yrs old but my son is even bigger than most 12 yr olds.
