Rm4278; No Vyvanse does not need time to kick in but it may take a day or two for you to notice what it is doing. But it is not timed release or the type of medicine that takes time to get a blood level. most say give it a week to really notice even more so if you are switching from another medication in the same class. Good luck. free discount card
