I don't understand. If you are over 18, the meds should be prescribed to you. Chances are that the doctors office is still going by what happened in high school. Call them and tell them to change the name on the prescription.
Of course, the other thing to do is to show your parents something like this chart. http://www.leeheymd.com/charts/adhd_1.html.
