For ADHD "My 9-year-old son has ADHD. Kapvay was the seventh medicine that we have tried to help him with impulsivity and concentration. He has been on this medicine for nearly one year. We switched to Focalin last month, but the tics came back and the restlessness at night. His school performance was no better than before, so we are back to Kapvay. Since the medicine must build up in the bloodstream to be highly effective, we are in the very sleepy stages, but I know this will pass as soon as his body is accustomed to the medicine. I have learned my lesson. There is no stimulant that will help my son. Kapvay will help reduce the impulsivity, but improvement to concentration must come from age and proper training."

For ADHD "My 7-year-old daughter has been on Concerta 18mg for a year. She started to tolerate that medicine, but I did not want to increase the dosage. My doctor recommended we add Kapvay to her current Concerta dose. This has made all the difference. She is no longer bouncing off the walls, jumping on the couch, or leaving halfway through a meal. She is engaged, focused, and less moody. Her emotions are more regulated, and we did not tell her teacher, but she even commented on the change without us sharing the news. We are so happy, and this medicine is worth the time it takes to condition to the sleepiness that happens in the initial 2 weeks. Hope the changes stay."

For ADHD "I started my son on this medicine on Friday. He is doing well. No emotional breakdowns, no crying. The only issue I am having is he is falling asleep around noon every day. He hasn't had a nap since he was 16 months old. He is 7, going on 8. I can't imagine his teacher will be all that amused when he goes to sleep during class tomorrow."

For ADHD "My 6-year-old son was diagnosed with ADHD last year. I saw signs during the preschool years as he was kicked out of three schools. This has been a trying year as we started him on Concerta, Focalin 2.5, and Focalin ER. Intuniv: Although the stimulants were great and we saw the benefits, it was difficult for me to see the negative side effects (tics and meltdown). I had mentioned to my doctor a month ago about Clonidine to reduce side effects of stimulants. She declined as she was uncomfortable with providing adult medication to children. However, she contacted me about Kapvay, which has been wonderful. Day 6 and a bit sleepy, unlike Intuniv (sedated). I will keep you up to date."
