“My son takes 15 mg a day of a stimulant, but my friend’s son takes just 5 mg. The boys are the same age and nearly the same weight and height. Did our doctor make a mistake?”
The appropriate dosage for stimulants has nothing to do with a patient’s age, weight, or height. It’s based on the length of time required for the medication to enter that particular person’s bloodstream. As long as the medication is helping your son, and he’s not troubled by side effects, your doctor probably didn’t make a mistake.
