What it is
A mixture of four amphetamine salts (dextroamphetamine and amphetamine) available as immediate-release tablets and extended-release capsules. Schedule II controlled substance.
How it works
Increases synaptic concentrations of dopamine and norepinephrine by promoting their release from presynaptic neurons and inhibiting their reuptake via the dopamine and norepinephrine transporters.
Where it's used
Used in attention-deficit/hyperactivity disorder (ADHD) and narcolepsy.
FDA-approved use
Attention-deficit/hyperactivity disorder (ADHD) and narcolepsy.
Tracking it
Adderall is oral, which makes consistency the whole game — a simple daily check-off with a reminder beats memory every time. with a half-life of about 11 hours, a dose log also lets a tracker model the relative amount still in your system between doses.
