An adult dose of : Vyvanse (lisdexamfetamine) 70 mg. given in AM takes about 2 hours to start working and lasts 12-14 hours in most adults. If you are a rapid metabolizer, a dose of Adderall taken about an hour before Vyvanse (lisdexamfetamine) effects begin to diminish may carry you through. Another option is to add a non-stimulant adjunct like Intunive, titrating doses till you achieve optimal effects. After 4-6 weeks, its effect lasts 24/7.
