Thank you for giving me such clear information including your son's weight and height.You can safely increase your son's Concerta dose to 54mg which is the maximum recommended daily dose of this treatment for children aged 6 to 12 years.This would be better than adding Ritalin in the morning.I am sure that you know that Ritalin and Concerta are the same medicines namely methylphenidate hydrochloride. The Concerta is just a slow release form of methylphenidate.
