Variable: Because vyvanse (lisdexamfetamine) is a pro-drug, it's activity in the CNS depends on cleaving lysine from the drug. This is rate limiting and provides about 12-16 hours of Dexedrine activity.
Dr. Elizabeth Finley-Belgrad
Child Psychiatry 34 years experience
Not long: Half life of vyvance is about 9.5 hours(length of time to metabolize 1/2 the dose. Should be pretty much out of your body within 24hrs.
