My 7-year-old son was recently diagnosed with ADHD. We started him on Focalin last week and it completely changed his personality. Made him withdrawn, irritable and slightly depressed. Other people noticed the change in him. This is obviously not what we wanted. We want to help him get his impulsive behavior under control and help him pay attention in school. We stopped the medication immediately. His doctor recommended taking a week off and then starting him on 10 mg. of Vyvanse next week. Anyone have any experience with this drug? Any insight would be great. This condition is so much more complicated than I realized.
