Evaluating the Methylphenidate Patch to Treat Former Stimulant Users With ADHD

Subjects will be provided with a 7-day supply of medication at each study visit. The dose will be flexible and will be titrated based on effect and tolerability. Unless a subject is experiencing side effects, the dose will be increased if a 25% reduction in ADHD symptoms as determined by the WRAADDS is not obtained. A proposed dosing schedule is as follows: Week 1: 12.5 cm2, Week 2: 18.75 cm2, Week 3: 25 cm2, Week 4: 37.5 cm2. The dose may be decreased as needed for tolerability.
