My 10 year old son, who is ADHD, was taking 30 mg of Vyvanse and it worked fine for like a month and half. The doctor increased his dosage to 40 mg and it was working great, but again the effects seemed to have diminished in two months. The doctor recommended to keep him in the 40 mg of Vyvanse, which he takes in the morning, and in the evening give him 1 mg of Intuniv. Do you know if that will help with his concentration at school?
Thank you
