The half life of Adderall is about 10 hours. If you took one 15 mg tablet at 12 noon, then you would have 7.5 mg in your system at 10:00 pm. It takes approximately 2 days (55 hours) for Adderall to completely leave your system.

An 15mg dosage of Adderall XR would last around 12 hours; certain factors can modify this time plus or minus (acidic food, tolerance, amount of fluids).

Is it safe to take adderall when you are taking Xnax?

You really shouldn't be on a prescription for Adderall and Xanax at the same time. It's possible that Adderall could potentiate the effects of the xanax. That means that if you mix them, you normal dose of Xanax could knock you out. It also depends on if you are taking Adderall because you have been diagnosed with ADD. The effects of Adderall are different for people who do not have ADD.
