Adderall (dextroamphetamine and racemic amphetamine) XR is an: Amphetamine preparation for treatment of adhd. The 'mean elimination half-life' for d-amphetamine is 10-13 hours (faster in children) and it should completely clear within 24 hours. There is no unexpected accumulation at steady state in children. Alkaline urine phs result in reduced renal elimination, and acidic phs and high flow rates result in increased renal elimination. Best regards.

Pretty Quickly: Although it is an extended release preparation, most of a dose of Adderall (dextroamphetamine and racemic amphetamine) xr will be out of the body after 24 hours, and it should be completely out of the body within a few days. Adderall (dextroamphetamine and racemic amphetamine) is not stored in the body, so the length of time is stays in the body is purely a function of how quickly it gets metabolized.

The half life is 10 : Hours. For a drug to leave your system it takes 5 half-lives or 50 hours, so about 2 days.

This depends: This depends on what time you take the Adderall (dextroamphetamine and racemic amphetamine) xr. Duration of effect is generally 10-12 hours. People usually take it in the morning in order to have focus in the day and be able to sleep at night. There may still be some in your system at night but not enough to disturb your sleep. If you are having sleep difficulty though, please tell your doctor.

Depends a bit: There are factors that can affect time to elimination of dextroamphetamine such as the pH of the urine, how much drug has been taken...but on average I would say you're looking at about 2.5-3 days from last dose to have about 98% out of your system.
