Methylphenidate
"My 9yr old son has been on it Metadate 20mg for over a year now. Only side effect is lost of appetite so I make him eat a big breakfast. He only takes it on the week days for school it has really helped him to focus. My sons grade improved from 60's to 90's. I like Metadate because by the time he's out from school the medication has warn off and he's back to his normal active self. During the summer I also give him a break from the med and we do not have to tapper off in order for him to stop. We've tried other medications that which had not so good side effects. Metadate so far is the best."
