How long will a Vyvanse stay in your system for if you only take one?

12-14 hours: Vyvanse is dosed once a day, in the am. Because the lysine has to be cleaved from the mixed amphetamine salts, its onset of action is about 2 hours after taking it. Plan your dose according to the time of your first academic class or your work. On urine drug testing it shows up as amphetamine; student athletes have to show an empty prescription bottle to the coach. ...Read more

Over 24 hours: Vyvanse is the longest acting oral stimulant; at high enough doses, amphetamine can be detected the next day, although at fairly low concentrations. Still, like with other stimulants, it seems to be effective only on days taken. There is not evidence of which i'm aware that it accumulates over time--though it might at the highest doses. ...Read more

Meaning: It depends on what you mean. the standard half-life of the active metabolite is about 10 hours, but there is individual variation. The weight and the sweating have little effect. But progessively smaller amounts will take additional half-lives. The clinical effect is commonly gone after 10 hours, or less. ...Read more

Half-life: Half-life is time required to drop current dose/level by 50%. We estimate it takes 5 half-lives to get something out of your body (~3.125%). Of course, this also depends upon your metabolism, health of liver & kidneys & other drugs. Check out http://www.drugs.com/pro/vyvanse.html which notes that lisdexamfetamine is a prodrug that's converted in body into active dextroamphetamine. 96% out in 120hr ...Read more

How long does it take to get high doses of Vyvanse completely of of your system?

Not too long : Generally most stimulant medications have been metabolized and are not producing much beneficial effect by 8 to 10 hours after they are taken. Metabolism of drugs vary and some patients lose the effect much earlier in the day and some have some residual effect that causes sleep issues. They do not have to build up in your system to produce effect and if you skip a dose you will not have benefit. ...Read more
