The information at Drugs.com is not a substitute for medical advice. ALWAYS consult your doctor or pharmacist.
General Instructions for Use
Vyvanse should be taken in the morning with or without food. Afternoon doses should be avoided because of the potential for insomnia.
Vyvanse capsules may be taken whole, or the capsule may be opened and the entire contents dissolved in a glass of water. The solution should be consumed immediately and should not be stored. The dose of a single capsule should not be divided. The contents of the entire capsule should be taken, and patients should not take anything less than one capsule per day.
Initiation Treatment
The recommended starting dose is 30 mg once daily in the morning in patients ages 6 and above. Dosage may be adjusted in increments of 10 mg or 20 mg at approximately weekly intervals up to maximum dose of 70 mg/day; Doses greater than 70 mg/day have not been studied.
Dosage should be individualized according to the therapeutic needs and response of the patient. Vyvanse should be administered at the lowest effective dosage. The least amount of Vyvanse feasible should be prescribed or dispensed at one time in order to minimize the possibility of overdosage.
Maintenance/Extended Treatment
​It is generally agreed that pharmacological treatment of ADHD may be needed for extended periods. The benefit of maintaining adult patients (ages 18-55 years) with ADHD on Vyvanse was demonstrated in a controlled randomized withdrawal trial [see Clinical Studies (14)]. Subjects assigned to Vyvanse in the randomized withdrawal phase continued on the same dose used to confirm response in the open-label phase.
​The physician who elects to use Vyvanse for extended periods should periodically re-evaluate the long-term usefulness of Vyvanse for the individual patient. Where possible, drug administration should be interrupted occasionally to determine if there is a recurrence of behavioral symptoms sufficient to require continued treatment.
