He has been taking 35 mg of methylphenid daily, split into 3 doses. Now his doctor has changed him to 40 mg timed release focalin, taken each morning in one dose. After reading the recommended dosages, this seems like way too much. I don't want to overdose him. Am I looking at these dosages wrong? Does anyone else have a 45# child on 40 mg per day of focalin??
