Both immediate and extended versions of Adderall contain amphetamine and dextroamphetamine. Thus, the different forms of these drugs have the same potential side effects. The immediate form of Adderall comes in the form of a tablet. On the other hand, Adderall XR comes in a capsule form containing immediate form beads and extended form beads, which is how it gets its long-term effectiveness.
Taking one 20 mg capsule of Adderall XR is comparable to taking one 10 mg of immediate Adderall followed by another 10 mg pill after four hours. Some research suggests that immediate forms of this drug have a high risk of misuse and abuse. Some people report grinding up the pills and snorting the powder to hasten the onset of the medication effects.
