If you are using a general doctor for prescribing this, don't. A psychiatrist knows these meds better. They follow up better. They know which families of meds they are in so they won't waste your time prescriving teh same family of meds that didn't work last time.
Your child's teacher will be a great person to get feedback from so schedule some meetingd with her to let her know he'll start a med and when it is effective and what changes she sees or not. You take note too along with any other person over 16 in your family.
A good ADD counselor will also be helpful. They know tricks that make studying and memorizing a bit easier for them. They know how to help them socialize better and understand body language signals better. There are some classic things that really work.
If you ever have problems at the school with his IEP and accommodations, one thing I did was draft a letter showing my child's strengths and weaknesses. Sometimes, they were the same (e.g., stubborn also can mean persistent and tenacious. A benefit sometimes, a problem at others. Eagle to volunteer can also mean wants attention. Sensitive can also mean empathetic to others. the therapist made a little adjustment, signed it, and the Vice Principal thought he was a genious. That he wished he had a letter like that on every child in school. Anyway, it was a breakthrough moment.
With meds, my child began remembering what she read and said it was easy. Before that, she couldn't remember what the paragraph said right after she read it! Congrats on getting the diagnosis. Meds are important. AND so it counseling.
I read books (e.g., Teens and ADHD) and went to A.D.D. organizational meetings and/or bought their tapes (from seminars from those gatherings). We're still working on the depression that comes on and off with ADD and taking meds when you're out of college and the sleep disorder.
