How long does Adderall stay in your system (urine drug test)?
Medically reviewed by Drugs.com. Last updated on Oct 14, 2024.
The half life of Adderall is approximately 10 hours. This means that every 10 hours, half of the previous amount of Adderall in the body leaves your body.
For example, if you took 10mg of Adderall at 12AM (midnight), at 10AM 5mg of Adderall will be left in your body. At 8PM, 2.5mg will be left, and so forth until there is 0mg left in your body. As a guide it takes approximately 5.5 half lives for a drug to be out of your system.
For Adderall then it would take just over 2 days for a dose to be out of your system. (5.5 x 10 = 55 hours - which is just over 2 days). You should allow for longer (7 days) if you have taken Adderall frequently and at high doses.

Adderall vs Vyvanse - What's the difference between them?
The main difference between Adderall and Vyvanse is that Adderall is a mixture of four different kinds of amphetamine salts (one of which is dextroamphetamine) while Vyvanse only contains one type of amphetamine salt, called lisdexamfetamine. Lisdexamfetamine gets converted into dexamphetamine once it is in the body. One advantage of Vyvanse is that it may be less likely to be abused; although it is usually more expensive than Adderall, although both have cheaper generic forms available. Because both drugs contain amphetamines, they work in a similar way. Studies have shown that Vyvanse is just as effective as Adderall, and side effects, including the risk of dependence, are similar.
