The Right Dose for Your Child

Your child’s doctor will determine the starting dose and when to make adjustments (a process called titration). The recommended starting dose for Vyvanse (lisdexamfetamine dimesylate) is 30 mg once daily. The doctor will begin medication at a starting dose and, if needed, periodically increase or decrease it to help control ADHD symptoms and manage side effects. The doctor may sometimes stop Vyvanse treatment for a while to see if Vyvanse is still right for your child. Your child should take Vyvanse exactly as the doctor tells him or her to take it.

Once-daily Vyvanse is available in 7 dosage strengths

With 7 dosage strengths of Vyvanse, the doctor has the flexibility to customize treatment, to provide your child with symptom control and manage side effects. Have your child take Vyvanse exactly as prescribed by the doctor. See additional dosing information below.
