About Adderall Metabolism
Adderall (amphetamine/dextroamphetamine) is a prescription stimulant medication used to treat ADHD and narcolepsy. Understanding its elimination from the body is important for medication management and testing purposes.
Key Facts:
- Average half-life: 10-14 hours (varies by individual)
- Complete elimination: typically 4-5 half-lives (2-3 days)
- Peak urine concentration: 2-8 hours after dose
- Detection window: 1-4 days for most tests
FAQ
- What is a high level of Adderall in urine?
- Adderall is a 3:1 mixture of d- and l-enantiomers of amphetamine salts. Peak amphetamine concentrations in urine have been reported around 2,645–5,948 ng/mL after a single therapeutic dose. Samples at or above 500 ng/mL of amphetamine (a common GC-MS confirmatory cutoff) have been observed up to about 47 hours post dose. Results vary by dose, metabolism, hydration, and urine pH.
